Compared with the prior art, when the number of devices connected to the electronic device through the Bluetooth physical link is greater than a certain number, since the Bluetooth physical link is occupied, the electronic device cannot provide an idle Bluetooth physical link to establish a new Bluetooth connection. connection, so the electronic device will reject subsequent received Bluetooth connection requests and notify the connection initiator that the connection failed. However, in the Bluetooth connection method provided by this application, when the number of connected devices via the Bluetooth physical link is greater than the first threshold, the first electronic device will pass Reserving the Bluetooth service link of the second target device connected through the Bluetooth physical link and disconnecting the Bluetooth physical link, thus releasing the Bluetooth physical link for the first electronic device and the second electronic device to establish a Bluetooth connection road. The service status of the second target device is kept synchronized, thereby solving the problem that when the number of devices connected to the electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth, thereby improving user experience.

In a possible implementation manner, the method may further include: when the number of connectable devices is less than a second threshold, the first electronic device performs the first operation.

In a possible implementation manner, the converting the first Bluetooth connection with the second target device into a second Bluetooth connection includes: determining the second target device from the first target device ; Disconnect the Bluetooth physical link connection with the second target device.

In another possible implementation manner, the converting the first Bluetooth connection with the second target device into a second Bluetooth connection includes: determining the second target from the first target device device; disconnect the Bluetooth physical link with the second target device and reserve the Bluetooth physical link with the second target device.

Optionally, the second target device is the first target device with the longest idle time among the first target devices or the first target device with the lowest service priority among the first target devices, and the idle time is The time period between the last time when the Bluetooth service interaction with the first electronic device is performed and the current time.

In a possible implementation manner, the determining the second target device from the first target device includes: determining a third target device from the first target device, where the third target device is A device supporting the second Bluetooth connection; determining the second target device from the third target device, the second target device being the third target device with the longest idle time among the third target devices or the For the third target device with the lowest service priority among the third target devices, the idle time is the time between the time when the Bluetooth service interaction with the first electronic device last time and the current time.

In another possible implementation manner, after converting the first Bluetooth connection with the second target device into a second Bluetooth connection, the method further includes: when there is a target service, sending The two target devices send a second Bluetooth connection request, where the second Bluetooth request is used to request establishment of a Bluetooth physical link.

In a possible implementation manner, the performing the first operation on the first electronic device when the number of first target devices is greater than a first threshold includes: when the number of first target devices is greater than the first threshold , and the idle duration of the first target device is not less than a third threshold, the first electronic device performs the first operation; when the number of the first target devices is greater than the first threshold, and the When the idle durations of the first target devices are all less than the third threshold, the first electronic device sends a second indication to the second electronic device, and the second indication is used to instruct the second electronic device to pass through the third threshold. Four target devices establish a first Bluetooth connection with the first electronic device, and the first target device includes the fourth target device.

It can be understood that the number of Bluetooth physical links of the first electronic device is limited and establishing the first Bluetooth connection with the first electronic device needs to occupy the Bluetooth physical link of the first electronic device, so the first electronic device receives the first connection The request needs to determine whether there is currently an idle (unoccupied) Bluetooth physical link for establishing the first Bluetooth connection based on the relationship between the first target device number and the first threshold value.

When there is no idle Bluetooth physical link (that is, the number of the first target device is greater than the first threshold), the second target device is instructed to connect to the fourth target device that has established the first Bluetooth connection with the first electronic device, so that the second target device The second target device establishes a first Bluetooth connection with the first electronic device through the fourth target device as a relay agent. In this way, the second electronic device and the fourth target device share a bluetooth physical link to establish the first bluetooth connection with the first electronic device, no additional bluetooth physical link is needed, and one bluetooth physical link can be used by multiple devices to connect to the first bluetooth connection through bluetooth The electronic device thus solves the problem that when the number of devices connected to the electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth, which improves the user experience.

The motor 191 may also correspond to different vibration feedback effects for touch operations acting on different areas of the display screen 194 . The indicator 192 can be an indicator light, and can be used to indicate charging status, power change, and can also be used to indicate messages, missed calls, notifications, and the like. The SIM card interface 195 is used for connecting a SIM card.

The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the Android system with a layered architecture as an example to illustrate the software structure of the electronic device 100 .

FIG. 2 is a block diagram of the software structure of the electronic device 100 according to the embodiment of the present application. The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, the application program layer, the application program framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

The application layer can consist of a series of application packages. As shown in FIG. 2, the application package may include application programs such as camera, photo album, music, and settings.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions. As shown in Figure 2, the application framework layer can include window managers, content providers, view systems, resource managers, notification managers, etc.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc.

Content providers are used to store and retrieve data and make it accessible to applications. Said data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures.

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages. The notification information displayed in the status bar can disappear automatically after a short stay, such as a message reminder to inform the user that the download is complete. The notification manager can also be a notification that appears on the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, text information is prompted in the status bar, or the notification manager can also emit a prompt sound, such as electronic device vibration, indicator light flashing, and the like.

Android runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system. The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

A system library can include multiple function modules. For example: surface manager (surface manager), media library (media libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of various commonly used audio and video formats, as well as still image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc. 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. Wherein, the kernel layer may include hardware driver modules, such as display drivers, camera drivers, sensor drivers, etc., and the application framework layer may call the hardware driver modules of the kernel layer.

For ease of understanding, the following embodiments of the present application will take the electronic device with the structure shown in FIG. 1 and FIG. 2 as an example to introduce the photographing process of the electronic device.

The technical solutions involved in the following embodiments can all be implemented in the electronic device 100 having the above-mentioned hardware architecture and software architecture.

When a user uses a mobile phone, he often connects to other devices through the Bluetooth of the mobile phone. For example, the mobile phone is connected to the tablet computer for data transmission, the mobile phone is connected to the smart home appliance through Bluetooth, and the mobile phone is connected to the Bluetooth speaker to play music through Bluetooth. However, when the number of devices connected to the mobile phone through Bluetooth reaches a certain number, multiple devices will seize the Bluetooth link of the mobile phone, so that other devices will no longer be able to exchange data with the mobile phone through Bluetooth. For example, when the number of mobile phones connected via Bluetooth reaches 7, when the user operates other devices to connect to the mobile phone via Bluetooth, the screens of other devices will display text prompts such as unable to join the connection, unable to connect to the device, or connection failure, or the mobile phone is connected to other devices. It is displayed as unconnectable in the Bluetooth list. For this reason, the embodiment of the present application provides a Bluetooth connection method, which can solve the problem that when the number of devices connected to an electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth.

The Bluetooth connection method provided by the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. As shown in Figure 3, the Bluetooth connection method provided by the embodiment of the present application includes:

S301. The first electronic device receives a first Bluetooth request sent by the second electronic device.

Wherein, the first connection request is used for requesting establishment of the first Bluetooth connection. The first Bluetooth connection includes a Bluetooth physical link connection and a Bluetooth service link connection.

Exemplarily, the user wants to listen to the music played by the mobile phone (the first electronic device) through the Bluetooth headset (the second electronic device), and the user sends the first Bluetooth request to the mobile phone by operating the Bluetooth headset, and the mobile phone receives the first bluetooth request sent by the Bluetooth headset accordingly. A Bluetooth request.

Optionally, the first connection request may include a first sub-connection request and a second sub-connection request. Wherein, the first sub-connection request is used for requesting establishment of a Bluetooth physical link connection, and the second sub-connection request is used for requesting establishment of a Bluetooth service link connection. For example, the first electronic device may first receive the first sub-connection request sent by the second electronic device, and then receive the second sub-connection request sent by the second electronic device.

S302. The first electronic device judges whether the number of first target devices is greater than a first threshold? If yes, execute S303; if not, execute S304.

Wherein, the first target device is a device that establishes a first Bluetooth connection with the first electronic device.

Optionally, the first threshold may be 6.

It should be noted that the number of Bluetooth physical links of the first electronic device is limited and the establishment of the first Bluetooth connection with the first electronic device needs to occupy the Bluetooth physical link of the first electronic device, so the first electronic device receives the first connection The request needs to determine whether there is currently an idle (unoccupied) Bluetooth physical link for establishing the first Bluetooth connection based on the relationship between the first target device number and the first threshold value.

In the case that there is no idle Bluetooth physical link (that is, the number of the first target device is greater than the first threshold), by converting the first Bluetooth connection with the second target device in the first target device into a second Bluetooth connection The Bluetooth physical link is released for the first electronic device to establish a first Bluetooth connection with the second electronic device.

If there is an idle Bluetooth physical link (that is, the number of first target devices is not greater than the first threshold), the first electronic device establishes a first Bluetooth connection through the second electronic device through the idle Bluetooth physical link.

Exemplarily, the first electronic device may determine whether the number of the first target devices is greater than 6 through the protocol stack. If yes, execute S303; if not, execute S304. That is, the first electronic device executes S303 when the number of first target devices is 0, 1, 2, 3, 4, 5, and 6, and executes S304 when the number of first target devices is other values.

In a possible implementation manner, the first device may also determine whether the number of connectable devices is smaller than the second threshold, and if yes, perform S303, and if not, perform S304.

Exemplarily, the first electronic device can determine whether the number of connectable devices is less than 1 through the protocol stack. If yes, execute S303; if not, execute S304. That is, the first electronic device executes S303 when the number of connectable devices is 0, and executes S304 when the number of connectable devices is not 0.

In another possible implementation manner, the first electronic device may determine whether the number of currently available channels (that is, the number of currently available physical channels or the number of current idle channels) is 0? If yes, execute S303; if not, execute S304.

In yet another possible implementation manner, the first electronic device may also determine that the number of currently occupied channels is greater than the fourth threshold? If yes, execute S303; if not, execute S304. Wherein, the fourth threshold may be 6.

S303. The first electronic device converts the first Bluetooth connection with the second target device into a second Bluetooth connection.

Wherein, the first target device includes a second target device, and the second Bluetooth connection includes a Bluetooth service link connection.

Exemplarily, the first electronic device may send a Bluetooth low energy (bluetooth low energy, BLE) broadcast packet to the second target device, instructing the second target device to convert the current first Bluetooth connection to the second Bluetooth connection.

Optionally, after the first electronic device and the second target device establish the second Bluetooth connection, the first electronic device and the second target device may broadcast synchronization status and messages through Ble.

In a possible implementation manner, converting the first Bluetooth connection with the second target device to the second Bluetooth connection may include: first determining the second target device from the first target device; Bluetooth physical link connection between two target devices. Wherein, the second target device may be the first target device with the longest idle time (i.e. idle time or service idle time) among the first target devices or the first target device with the lowest service priority among the first target devices, and the idle time is The length of time between the last Bluetooth service interaction with the first electronic device and the current time (for example, the last Bluetooth service interaction with the first electronic device is 14:50:00, and the current time is 14:53:00 , the idle duration is 00:03:00).

In another possible implementation manner, converting the first Bluetooth connection with the second target device to the second Bluetooth connection may include: first determining the second target device from the first target device; The Bluetooth physical link between the second target devices is connected and the Bluetooth service link connection with the second target device is reserved.

It should be noted that the specific method for the first electronic device to determine the second target device from the first target device may be processed by any method conceivable by those skilled in the art, which is not specifically limited in this embodiment of the present application.

For example, the first electronic device may determine the first target device with the longest idle time (ie idle time or business idle time) among the first target devices as the second target device. The idle time is the time between the time when the Bluetooth service was last interacted with the first electronic device and the current time (for example, the time when the first target device interacted with the first electronic device for the Bluetooth service (excluding the keep-alive service) last time 14 :50:00, the current time is 14:53:00, then the idle time is 00:03:00).

For another example, the first electronic device may determine the first target device with the lowest service priority among the first target devices as the second target device.

For another example, the first electronic device may determine the score of the first target device according to various parameters of the first target device (such as the number of connections, connection duration, business priority, etc.), and then assign the first target device with the lowest score among the first target devices. The target device is determined to be the second target device.

Exemplarily, the first electronic device can obtain the priority queue table shown in Table 1 according to the order of the idle time of the first target device from small to large, and then assign the first target device ( That is, the device 7) is determined as the second target device, and then the Bluetooth physical link connection with the device 7 is disconnected.

Table 1

equipment idle time equipment 1 00:00:30 device 2 00:00:50 device 3 00:01:00 device 4 00:01:10 device 5 00:03:00 device 6 00:05:00 equipment 7 00:12:00

In a possible implementation manner, determining the second target device from the first target device may include: determining a third target device from the first target device, where the third target device is a device that supports the second Bluetooth connection; The second target device is determined in the third target device. Wherein, the second target device may be the third target device with the longest idle time among the third target devices or the third target device with the lowest service priority among the third target devices.

It should be noted that the specific method for the first electronic device to determine the third target device from the first target device may be processed by any method conceivable by those skilled in the art, which is not specifically limited in this embodiment of the present application.

For example, the first electronic device may determine whether the first target device supports the second Bluetooth connection according to parameters such as the model and brand of the first target device.

For another example, the first electronic device may send a test signaling for testing whether the device supports the second Bluetooth connection to the first target device to determine whether the first target device supports the second Bluetooth connection.

Compared with the prior art, when the number of devices connected to the electronic device through the Bluetooth physical link is greater than a certain number, since the Bluetooth physical link is occupied, the electronic device cannot provide an idle Bluetooth physical link to establish a new Bluetooth connection. connection, so the electronic device will reject subsequent received Bluetooth connection requests and notify the connection initiator that the connection failed. However, in the Bluetooth connection method provided by the embodiment of the present application, when the number of connected devices through the Bluetooth physical link is greater than the first threshold, the first electronic device subsequently receives the Bluetooth connection request sent by the second electronic device, By reserving the Bluetooth service link of the second target device connected through the Bluetooth physical link and disconnecting the Bluetooth physical link, the Bluetooth connection for the first electronic device and the second electronic device to establish a Bluetooth connection is released. physical link. The service status of the second target device is kept synchronized, thereby solving the problem that when the number of devices connected to the electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth, thereby improving user experience.

S304. The first electronic device establishes a first Bluetooth connection with the second electronic device.

In a possible implementation manner, if there is a target service, the first electronic device sends the first indication to the second target device. Wherein, the target service is a Bluetooth service related to the second target device, and the first indication is used to instruct the second target device to establish a Bluetooth physical link connection with the first electronic device.

In another possible implementation manner, if there is a target service, the first electronic device may also send a second Bluetooth connection request to the second target device. Wherein, the second Bluetooth request is used to request to establish a Bluetooth physical link.

As shown in (a) of FIG. 4 , the first Bluetooth connection includes a Bluetooth physical link connection and a Bluetooth service link connection. The upper-layer business of the device can exchange service data flow with the Bluetooth physical link port of the device through the Bluetooth service link, and the Bluetooth physical link port of the device passes the Bluetooth physical link and the Bluetooth physical link port service data flow of the peer device. As shown in (b) in Figure 4, when the Bluetooth physical link connection between device 1 and device 2 is disconnected and the Bluetooth service link connection is reserved, since the Bluetooth service link connection is reserved, device 1 or device 2 2's upper-layer services can still exchange service data streams to the Bluetooth physical link port of the device through the Bluetooth service link. Therefore, after the first electronic device converts the first Bluetooth connection with the second target device into the second Bluetooth connection, the upper-layer services of the first electronic device can still communicate with the Bluetooth physical connection of the first electronic device through the Bluetooth service link. The link port exchanges target services (that is, the service data flow of the Bluetooth service related to the second target device), and the first electronic device can judge whether there is a target service through the Bluetooth physical link port of the first electronic device, and if there is a target service , it is necessary to establish a Bluetooth physical link to transmit the data stream of the target service. Therefore, when there is a target service, the first electronic device sends to the second target device a first indication for instructing the second target device to establish a Bluetooth physical link connection with the first electronic device, and instructs the second target device to The first electronic device sends a first Bluetooth request to establish a first Bluetooth connection between the first electronic device and the second target device. Certainly, in the case that the target service exists, the first electronic device may also directly send the first Bluetooth request to the second target device to establish the first Bluetooth connection between the first electronic device and the second target device.

It should be noted that the specific method for the first electronic device to send the first indication to the second target device may be processed by any method conceivable by those skilled in the art, which is not specifically limited in this embodiment of the present application.

For example, when there is a target service, the first electronic device may send a first indication for instructing the second target device to establish a Bluetooth physical link connection with the first electronic device to the second target device through a Ble broadcast, indicating that the second The target device sends a first Bluetooth request to the first electronic device to establish a first Bluetooth connection between the first electronic device and the second target device.

It can be understood that the second target device can also judge whether there is a target service through the Bluetooth physical link port of the second target device, and if there is a target service, send a message indicating to the first electronic device to the first electronic device Establishing a second indication of a Bluetooth physical link connection with the second target device, instructing the first electronic device to send a first Bluetooth request to the first electronic device to establish a first Bluetooth connection between the first electronic device and the second target device, Alternatively, if there is a target service, the second target device may also directly send a first Bluetooth request to the first electronic device to establish a first Bluetooth connection between the first electronic device and the second target device.

When a user uses a mobile phone, he often connects to other devices through the Bluetooth of the mobile phone. However, when the number of devices connected to the mobile phone through Bluetooth reaches a certain number, multiple devices will seize the Bluetooth link of the mobile phone, so that other devices will no longer be able to exchange data with the mobile phone through Bluetooth. For example, when the number of mobile phones connected via Bluetooth reaches 7, when the user operates other devices to connect to the mobile phone via Bluetooth, the screens of other devices will display text prompts such as unable to join the connection, unable to connect to the device, or connection failure, or the mobile phone is connected to other devices. It is displayed as unconnectable in the Bluetooth list. For this reason, the embodiment of the present application provides another Bluetooth connection method, which can solve the problem that when the number of devices connected to an electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth.

Another Bluetooth connection method provided by the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. As shown in Figure 5, another Bluetooth connection method provided by the embodiment of the present application includes:

S501. The first electronic device receives a first Bluetooth request sent by the second electronic device.

Wherein, the first connection request is used for requesting establishment of the first Bluetooth connection. The first Bluetooth connection includes a Bluetooth physical link connection and a Bluetooth service link connection.

Exemplarily, the user wants to connect the Bluetooth of the air conditioner through the Bluetooth of the mobile phone (second electronic device) to adjust the temperature of the air conditioner, and the user sends a first Bluetooth request to the air conditioner by operating the mobile phone, and the air conditioner receives the sent first Bluetooth request accordingly.

Optionally, the first connection request may include a first sub-connection request and a second sub-connection request. Wherein, the first sub-connection request is used for requesting establishment of a Bluetooth physical link connection, and the second sub-connection request is used for requesting establishment of a Bluetooth service link connection. For example, the first electronic device may first receive the first sub-connection request sent by the second electronic device, and then receive the second sub-connection request sent by the second electronic device.

S502. The first electronic device judges whether the number of first target devices is greater than a first threshold? If yes, execute S503; if not, execute S504.

Wherein, the first target device is a device that establishes a first Bluetooth connection with the first electronic device.

Optionally, the first threshold may be 6.

It should be noted that the number of Bluetooth physical links of the first electronic device is limited and the establishment of the first Bluetooth connection with the first electronic device needs to occupy the Bluetooth physical link of the first electronic device, so the first electronic device receives the first connection The request needs to determine whether there is currently an idle (unoccupied) Bluetooth physical link for establishing the first Bluetooth connection based on the relationship between the first target device number and the first threshold value.

When there is no idle Bluetooth physical link (that is, the number of the first target device is greater than the first threshold), the second target device is instructed to connect to the fourth target device that has established the first Bluetooth connection with the first electronic device, so that the second target device The second target device establishes a first Bluetooth connection with the first electronic device through the fourth target device as a relay agent. In this way, the second electronic device and the fourth target device share a bluetooth physical link to establish the first bluetooth connection with the first electronic device, no additional bluetooth physical link is needed, and one bluetooth physical link can be used by multiple devices to connect to the first bluetooth connection through bluetooth The electronic device thus solves the problem that when the number of devices connected to the electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth, which improves the user experience.

If there is an idle Bluetooth physical link (that is, the number of first target devices is not greater than the first threshold), the first electronic device establishes a first Bluetooth connection through the second electronic device through the idle Bluetooth physical link.

Exemplarily, the first electronic device may determine whether the number of the first target devices is greater than 6 through the protocol stack. If yes, execute S503; if not, execute S504. That is, the first electronic device executes S503 when the number of first target devices is 0, 1, 2, 3, 4, 5, and 6, and executes S504 when the number of first target devices is other values.

In a possible implementation manner, the first device may also determine whether the number of connectable devices is smaller than the second threshold, and if yes, perform S503, and if not, perform S504.

Exemplarily, the first electronic device can determine whether the number of connectable devices is less than 1 through the protocol stack. If yes, execute S503; if not, execute S504. That is, the first electronic device executes S503 when the number of connectable devices is 0, and executes S504 when the number of connectable devices is not 0.

In a possible implementation manner, the first electronic device may determine whether the number of currently available channels (that is, the number of currently available physical channels or the number of current idle channels) is 0? If yes, execute S503; if not, execute S50.

In another possible implementation manner, the first electronic device may also determine that the number of currently occupied channels is greater than the fourth threshold? If yes, execute S503; if not, execute S504. Wherein, the fourth threshold may be 6.

S503. The first electronic device sends a second instruction to the second electronic device to instruct the second electronic device to establish a first Bluetooth connection with the first electronic device through a fourth target device in the first target device.

In a possible implementation manner, the first electronic device sending the second indication to the second electronic device may include: the first electronic device first determines the fourth target device from the first target device, and then sends the second electronic device The device sends a second indication.

It should be noted that the specific method for the first electronic device to first determine the fourth target device from the first target device can be processed by any method conceivable by those skilled in the art, which is not specifically limited in this embodiment of the present application. .

For example, the first electronic device may first obtain the number of connected devices of each first target device (the number of connected devices via Bluetooth), and then determine the device with the smallest number of connected devices among the first target devices as the fourth target device.

Exemplarily, the first electronic device may acquire the number of connected devices of each first target device by sending an acquisition instruction to each first target device, and then obtain the number of connected devices of each first target device according to the number of connected devices of the first target device The first target device information table shown in Table 2 is sequentially obtained, and then the first target device (ie, device 4 ) of the number of connected devices in Table 2 is determined as the fourth target device. Of course, the first electronic device may also determine any first target device whose number of connected devices is less than the first threshold as the fourth target device.

Table 2

Optionally, the obtaining instruction for obtaining the number of connected devices may be a hiecho instruction. Table 3 shows the format of the hiech o command. As shown in Table 3, the command id field of the hiecho command can be used to add and define the command type, and the payload field of the hiecho command can be used to store data.

table 3

header service id command id payload mic

In a possible implementation manner, the first electronic device may also send a third indication to the fourth target device to instruct the fourth target device to establish the first Bluetooth connection with the second electronic device as a relay agent.

Compared with the prior art, when the number of devices connected to the electronic device through the Bluetooth physical link is greater than a certain number, since the Bluetooth physical link is occupied, the electronic device cannot provide an idle Bluetooth physical link to establish a new Bluetooth connection. connection, so the electronic device will reject subsequent received Bluetooth connection requests and notify the connection initiator that the connection failed. However, in the Bluetooth connection method provided by the embodiment of the present application, when the number of connected devices through the Bluetooth physical link is greater than the first threshold, the first electronic device subsequently receives the Bluetooth connection request sent by the second electronic device, Instructing the second target device to connect to the fourth target device that has established the first Bluetooth connection with the first electronic device, so that the second target device establishes the first Bluetooth connection with the first electronic device through the fourth target device as a relay agent. In this way, the second electronic device and the fourth target device share a bluetooth physical link to establish the first bluetooth connection with the first electronic device, no additional bluetooth physical link is needed, and one bluetooth physical link can be used by multiple devices to connect to the first bluetooth connection through bluetooth The electronic device thus solves the problem that when the number of devices connected to the electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth, which improves the user experience.

It should be noted that the Bluetooth protocol supports different service interactions through different DLCs on the same Bluetooth physical link, so the second electronic device and the fourth target device can use the same Bluetooth physical link and the fourth target device through different DLCs. An electronic device performs service interaction.

For example, if the first electronic device sends a service data stream to the second electronic device, the first electronic device can obtain the information of the connected devices of each first target device, and then obtain the connected device information table shown in Table 4, and then according to The connected device information table determines that the DLC used by the second electronic device is B_4, and then sends the service data stream with the DLC of B_4 to the fourth target device, and the fourth target device receives the service data stream according to the DLC or DLC of the service data stream. The MAC and DLC lookup table 4 of the service data flow determines that the DLC of the data flow is not A_B used for interaction between the first electronic device and the fourth target device, but B_4 used by the first electronic device and the second electronic device , and then transmit the data stream to the second electronic device through the Bluetooth physical link between the fourth target device and the second electronic device.

Table 4

It can be understood that, after receiving the service data flow sent by the fourth target device, the first electronic device may also determine the sender of the data flow through the DLC of the service data flow or the MAC and DLC lookup table 4 of the service data flow.

When a user uses a mobile phone, he often connects to other devices through the Bluetooth of the mobile phone. However, when the number of devices connected to the mobile phone through Bluetooth reaches a certain number, multiple devices will seize the Bluetooth link of the mobile phone, so that other devices will no longer be able to exchange data with the mobile phone through Bluetooth. For example, when the number of mobile phones connected via Bluetooth reaches 7, when the user operates other devices to connect to the mobile phone via Bluetooth, the screens of other devices will display text prompts such as unable to join the connection, unable to connect to the device, or connection failure, or the mobile phone is connected to other devices. It is displayed as unconnectable in the Bluetooth list. For this reason, the embodiment of the present application provides another Bluetooth connection method, which can solve the problem that when the number of devices connected to an electronic device through Bluetooth reaches a certain number, other devices will no longer be able to perform data interaction with the electronic device through Bluetooth.

Another Bluetooth connection method provided by the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. As shown in FIG. 6, another Bluetooth connection method provided by the embodiment of the present application includes:

S601. The first electronic device receives a first Bluetooth request sent by the second electronic device.

Wherein, the first connection request is used for requesting establishment of the first Bluetooth connection. The first Bluetooth connection includes a Bluetooth physical link connection and a Bluetooth service link connection.

Optionally, the first connection request may include a first sub-connection request and a second sub-connection request. Wherein, the first sub-connection request is used for requesting establishment of a Bluetooth physical link connection, and the second sub-connection request is used for requesting establishment of a Bluetooth service link connection. For example, the first electronic device may first receive the first sub-connection request sent by the second electronic device, and then receive the second sub-connection request sent by the second electronic device.

S602. The first electronic device judges whether the number of first target devices is greater than a first threshold? If yes, execute S603; if not, execute S605.

S603. The first electronic device judges whether the idle duration of the first target device is less than a third threshold, and if yes, executes S606, and if not, executes S604.

It should be noted that whether the service interaction between the first target device and the first electronic device is frequent can be determined according to the relationship between the idle duration of the first target device and the magnitude of the third threshold. When the idle duration of the first target device is less than the third threshold, it means that each first target device frequently interacts with the first electronic device. At this time, if S604 is executed to convert the first Bluetooth connection of a first target device The second Bluetooth connection will affect the business interaction between the first target device and the first electronic device, and by executing S606 to select a certain first target device as a relay agent, the relationship between the first electronic device and the second electronic device can be established. The first Bluetooth in between does not affect the service interaction between the first target device and the first electronic device.

When the idle duration of the first target device is not less than the third threshold, it means that there is a first target device in the first target device that does not frequently interact with the first electronic device. By performing S604, the first Bluetooth The connection conversion is converted into a second Bluetooth connection conversion to release the Bluetooth physical connection occupied by the first target device for the first electronic device to establish a first Bluetooth connection with the second electronic device.

It can be understood that, in the case of whether the number of the first target devices is greater than the first threshold, the first electronic device may also judge whether to execute S604 or 606 through other judgment conditions, which is not limited in this embodiment of the present application.

For example, the first electronic device may determine whether to perform S604 or S606 according to the priority of the second electronic device. When the priority of the second electronic device is higher (that is, greater than the priority threshold), execute S604 so that the second electronic device establishes a first Bluetooth connection with the first electronic device through a separate Bluetooth physical link. When the priority of the second electronic device is low (that is, less than the priority threshold), execute S606 so that the second electronic device shares the Bluetooth physical link with the fourth target device to establish a first Bluetooth connection with the first electronic device.
