This application claims priority to the Chinese patent application filed with the China Patent Office on August 23, 2023, with application number 202311069946.9 and application name “Device connection method, device, electronic device and computer storage medium”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the technical field of Bluetooth connection, and in particular to a device connection method, apparatus, electronic device and computer storage medium.

Background Art

For another example, a mobile phone and a TV can establish a Bluetooth connection, and the mobile phone can send audio and video to the TV for playback through the Bluetooth connection.

After the speaker and the TV establish a Bluetooth connection, the speaker can control the playback, pause, etc. of the audio in the TV according to the audio and video remote control protocol (Audio Video Remote Control Profile, Avrcp) in Bluetooth. At this time, the speaker acts as the control device (Controller, CT) in the audio and video remote control protocol, and the TV acts as the controlled device (Target, TG) in the audio and video remote control protocol. After the mobile phone and the TV establish a Bluetooth connection, the TV can control the playback, pause, etc. of the audio and video in the mobile phone according to the audio and video remote control protocol (Audio Video Remote Control Profile, Avrcp) in Bluetooth. At this time, the TV acts as the control device (Controller, CT) in the audio and video remote control protocol, and the mobile phone acts as the controlled device (Target, TG) in the audio and video remote control protocol.

Currently, the TV can only be used as a controlled device in the audio and video remote control protocol, and cannot be used as a controlling device.

In order to facilitate the description of the device connection method of the present application, the device connection device will be integrated in the terminal for detailed description, that is, the terminal will be taken as an example of an electronic device and the terminal will be used as the execution subject for detailed description.

Please refer to FIG1 , which is a flow chart of a device connection method provided by an embodiment of the present application. The device connection method is applied to an electronic device, and the electronic device supports a controlled service and a control service. The device connection method may include:

S101, obtaining a Bluetooth initialization instruction, and registering a callback function of the controlled service and a callback function of the control service with an audio and video remote control protocol according to the Bluetooth initialization instruction.

The electronic device supports controlled services, which means that the electronic device stores programs that allow the electronic device to act as a controlled device (Television, TG) in the connection of an audio and video remote control protocol. The electronic device supports control services, which means that the electronic device stores programs that allow the electronic device to act as a controlling device (Controller, CT) in the connection of an audio and video remote control protocol.

In an embodiment of the present application, after obtaining the Bluetooth initialization instruction, the terminal performs Bluetooth initialization according to the Bluetooth initialization instruction. During the Bluetooth initialization process, the controlled service and the control service are initialized. During the initialization of the controlled service and the control service, the callback function of the controlled service and the callback function of the control service are registered for the audio and video remote control protocol.

Among them, registering the callback function of the controlled service and the callback function of the control service with the audio and video remote control protocol can be understood as registering the callback function of the controlled service and the callback function of the control service to the application layer where the audio and video remote control protocol is located, so that the connection of the audio and video remote control protocol can be established subsequently according to the registered callback function.

Optionally, in order to facilitate calling the registered callback function when establishing a connection of the audio and video remote control protocol, the process of registering the callback function of the controlled service and the callback function of the control service for the audio and video remote control protocol according to the Bluetooth initialization instruction can be:

According to the Bluetooth initialization instruction, the callback function of the controlled service and the callback function of the control service are registered with the audio and video remote control protocol, and the first identifier corresponding to the callback function of the control service and the second identifier corresponding to the callback function of the controlled service are obtained.

For example, as shown in FIG. 2 , the first identifier may be 1, the second identifier may be 2, the AvrcpCT service refers to the control service, and the AvrcpTG service refers to the controlled service.

Optionally, the terminal can obtain the Bluetooth initialization instruction in response to the user's operation, or the terminal can also generate the Bluetooth initialization instruction according to the Bluetooth startup instruction, or the terminal can also receive the Bluetooth initialization instruction sent by other terminals. The way in which the terminal obtains the Bluetooth initialization instruction can be selected according to actual conditions, and the embodiments of the present application are not limited here.

Optionally, after the Bluetooth initialization is completed, the terminal can establish a Bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2DP) connection with the target device, so that multimedia can be transmitted between the target device and the terminal through the Bluetooth audio transmission model protocol connection.

Multimedia is a combination of various media, which may include at least one of text, sound, image and video.

When the terminal and the target device establish a connection based on the Bluetooth audio transmission model protocol, the target device can be the source device (Audio Source) and the terminal can be the receiving device (Audio Sink), or the target device can be the receiving device and the terminal can be the source device.

When the target device acts as a source device and the terminal acts as a receiving device, the multimedia transmission direction is from the target device to the terminal. When the target device acts as a receiving device and the terminal acts as a source device, the multimedia transmission direction is from the terminal to the target device.

For example, when the target device is a speaker and the terminal is a TV, the speaker is the receiving device and the TV is the source device, and the multimedia transmission direction is from the TV to the speaker. For another example, when the target device is a mobile phone and the terminal is a TV, the TV is the receiving device and the mobile phone is the source device, and the multimedia transmission direction is from the mobile phone to the TV.

S102: Obtain a control connection request sent by a target device for an audio and video remote control protocol, and obtain a first target service supported by the target device according to the control connection request.

The control connection request sent by the target device for the audio and video remote control protocol refers to a control connection request used to establish a connection for the audio and video remote control protocol.

After obtaining the control connection request, the terminal obtains a first target service supported by the target device. The first target service includes at least one of a first controlled service and a first control service.

When the first target service includes the first controlled service, it means that the target device can be used as a controlled device (TG) in the connection of the audio and video remote control protocol. When the first target service includes the first control service, it means that the target device can be used as a control device (CT) in the connection of the audio and video remote control protocol.

Optionally, the terminal may obtain the first target service supported by the target device from the target device according to the control connection request, or the terminal may obtain the first target service supported by the target device from the server according to the control connection request. Alternatively, the terminal may also obtain the first target service supported by the target device from the local storage space according to the control connection request.

The method for obtaining the first target service supported by the target device can be selected according to actual conditions, and the embodiment of the present application does not limit this.

In some embodiments, the electronic device establishes a connection with the first target device using an audio and video remote control protocol; and according to the control connection request, obtains a first target service supported by the target device, including:

According to the control connection request, obtaining the priority of the target device and the priority of the first target device;

If the priority of the target device is higher than the priority of the first target device, disconnecting the audio and video remote control protocol connection with the first target device;

Gets the first target service supported by the target device.

Since the terminal can establish audio and video remote control protocol connections with multiple devices, the priority of each device can be set to determine which device to establish the audio and video remote control protocol connection with according to the priority of each device.

If the priority of the target device is lower than the priority of the first target device, the connection of the audio and video remote control protocol with the target device is not disconnected.

In an embodiment of the present application, a controlled service and a control service coexist in a terminal, and during the Bluetooth initialization process, the callback function of the controlled service and the callback function of the control service are registered for the audio and video remote control protocol, so that even if the role played by the terminal in the connection with the audio and video remote control protocol of the target device and the role played by the terminal in the connection with the audio and video remote control protocol of the first target device are different, there is no need to restart the controlled service or the control service.

For example, in the connection of the audio and video remote control protocol with the target device, the role of the terminal is the control device, and in the connection of the audio and video remote control protocol with the first target device, the role of the terminal is the controlled device. Even if the terminal first establishes a connection of the audio and video remote control protocol with the first target device, there is no need to restart the control service when establishing a connection of the audio and video remote control protocol with the target device.

S103: Filter out services matching the first target service from the controlled services and the control services, and obtain a second target service for the control connection request.

The service matching the first target service refers to a service that is complementary to the first target service. For example, when the first target service is the first controlled service, the target device is the controlled device, the second target service is the control service, and the terminal is the control device. For another example, when the first target service is the first control service, the target device is the control device, the second target service is the controlled service, and the terminal is the controlled device.

Optionally, when the first target service includes a first controlled service and a first control service, the process of filtering out a service matching the first target service from the controlled service and the control service to obtain a second target service for the control connection request is:

Obtain target screening strategies;

Filter services matching the target screening policy from the first controlled service and the first control service to obtain a third target service;

A service matching the third target service is screened out from the controlled service and the control service to obtain a second target service for the control connection request.

For example, when the third target service is the first controlled service, the second target service is the controlling service. For another example, when the third target service is the first controlling service, the second target service is the controlled service.

The target screening strategy can be set according to the actual situation, and the present application embodiment does not limit it here. For example, the process of obtaining the target screening strategy can be:

Obtaining the transmission direction of multimedia between the target device and the electronic device;

Determine the target screening strategy based on the transmission direction.

Since the target device and the terminal have transmitted multimedia via the connection of the Bluetooth audio transmission model protocol, the target screening strategy can be determined according to the transmission direction of the multimedia between the target device and the electronic device.

If the transmission direction is from the target device to the terminal, at this time, the target device is the source device and the terminal is the receiving device, then the target screening strategy is to screen out the first controlled service, the third target service is the first controlled service, and the second target service is the control service. If the transmission direction is from the terminal to the target device, at this time, the terminal is the source device and the target device is the receiving device, then the target screening strategy is to screen out the first control service, the third target service is the first control service, and the second target service is the controlled service.

For example, the target device is a speaker, the terminal is a TV, and the transmission direction is from the TV to the speaker. The speaker serves as a control device, the service used by the speaker is the first control service, and the target screening strategy is to screen out the first control service.

For another example, the target device is a mobile phone, the terminal is a TV, and the transmission direction is from the mobile phone to the TV. The mobile phone is the controlled device, the service used by the mobile phone is the first controlled service, and the target screening strategy is to screen out the first controlled service.

For another example, the process of obtaining the target screening strategy can also be:

Get the startup status of the target application;

Determine the target screening strategy based on the startup status.

In an embodiment of the present application, a target application can be set separately, and then when the startup state of the target application is started, the first control service is used as the third target service, and when the startup state of the target application is closed, the first controlled service is used as the third target service.

It should be noted that, when the startup state is startup, the first controlling service can be used as the third target service, and the first controlled service can also be used as the third target service, which is not limited in the embodiment of the present application.

For another example, the process of obtaining the target screening strategy can also be:

Get the historical target service of the target device;

Determine target screening strategy based on historical target services.

In an embodiment of the present application, if the target device and the terminal establish a connection via an audio and video remote control protocol, a target screening strategy may be determined based on the historical target services of the target device.

For example, the historical target service is the first controlled service, and the target device established an audio and video remote control protocol connection with the terminal through the first controlled service at time A in the past. Then the target screening strategy is to screen out the first controlled service.

For another example, the historical target service is the first control service, and the target device established an audio and video remote control protocol connection with the terminal through the first control service at time A in the past, then the target screening strategy is to screen out the first control service.

Optionally, if there are multiple historical target services and the multiple historical target services are different, the target filtering strategy can be determined based on the historical target service corresponding to the time closest to the current time, or, the target filtering strategy can be determined based on the historical target service that appears the most times, or, the target filtering strategy can be determined based on the historical target service corresponding to the time that matches the current time.

For example, there are 10 historical target services, including a first controlled service and a first controlling service, and the historical target service corresponding to the time closest to the current time is the first controlling service. Then, the target screening strategy is determined according to the first controlling service.

For another example, there are 10 historical target services, including a first controlled service and a first controlling service. The first controlled service appears 7 times, and the first controlling service appears 3 times. Then, the target screening strategy is determined according to the first controlled service.

For another example, there are 10 historical target services, including the first controlled service and the first controlling service. The current time is A time a, and the historical target service corresponding to A time b is the first controlled service. B is before a. Then, the target screening strategy is determined based on the first controlled service.

S104: Establishing an audio and video remote control protocol connection with the target device according to the callback function after the second target service is registered.

If the first target service is a controlled service, then according to the callback function registered by the controlled service, a connection of the audio and video remote control protocol is established with the target device; if the first target service is a control service, then according to the callback function registered by the control service, a connection of the audio and video remote control protocol is established with the target device.

After the callback function of the controlled service and the callback function of the control service are registered, the first identifier corresponding to the callback function of the control service and the second identifier corresponding to the callback function of the controlled service can be obtained. According to the callback function after the second target service is registered, the process of establishing a connection of the audio and video remote control protocol with the target device can be:

If the second target service is a control service, establishing a connection of an audio and video remote control protocol with the target device according to the callback function corresponding to the first identifier;

If the second target service is a controlled service, a connection of an audio and video remote control protocol is established with the target device according to the callback function corresponding to the second identifier.

When the terminal establishes an audio and video remote control protocol connection with the target device according to the callback function registered by the controlled service, after the terminal establishes the audio and video remote control protocol connection with the target device, it can receive control instructions of the target device to control the multimedia in the terminal through the audio and video remote control protocol connection with the target device, and then control the multimedia according to the control instructions.

When the terminal establishes an audio and video remote control protocol connection with the target device according to the callback function registered with the control service, the terminal can control the multimedia in the target device through the audio and video remote control protocol connection with the target device.

Among them, the terminal controls the multimedia in the target device by connecting to the audio and video remote control protocol of the target device. The method can be selected according to actual conditions. For example, the multimedia in the target device can be controlled to pause, play, play the previous song or the next song, etc. The embodiment of the present application is not limited here.

In an embodiment of the present application, a controlled service and a control service coexist in a terminal, and the role of the terminal is determined according to the role of the target device. When the role of the target device is a controlled device, the role of the terminal is a control device, and when the role of the target device is a control device, the role of the terminal is a controlled device, so that when the terminal is connected to the audio and video remote control protocol of the target device, there will be no role errors, so that when the terminal acts as a control device and controls the multimedia in the target device through the connection with the audio and video remote control protocol of the target device, there will be no errors in the control of the multimedia, thereby improving the user experience and thus improving the utilization rate of the terminal.

As can be seen from the above, in the embodiment of the present application, a Bluetooth initialization instruction is obtained, and according to the Bluetooth initialization instruction, the callback function of the controlled service and the callback function of the control service are registered with the audio and video remote control protocol; a control connection request sent by the target device according to the audio and video remote control protocol is obtained, and according to the control connection request, the audio and video remote control protocol supported by the target device is obtained. A first target service; filtering out services matching the first target service from the controlled service and the control service to obtain a second target service for the control connection request; establishing an audio and video remote control protocol connection with the target device according to the callback function after the second target service is registered, thereby realizing the coexistence of the controlled service and the control service in the electronic device, and then deciding whether to establish an audio and video remote control protocol connection with the target device according to the callback function of the controlled service or to establish an audio and video remote control protocol connection with the target device according to the callback function of the control service according to the first target service supported by the target device, so that the electronic device can be used as both a controlled device and a control device in the audio and video remote control protocol, thereby improving the utilization rate of the electronic device.

The process of Bluetooth initialization provided in the embodiment of the present application is further described below with reference to FIG. 3 .

The terminal obtains a Bluetooth startup instruction, and performs Bluetooth service initialization according to the Bluetooth startup instruction. During the Bluetooth initialization process, the controlled service initialization and the control service initialization are performed.

During the process of initializing the control service, the terminal registers the callback function of the control service with the audio and video remote control protocol to obtain a first identifier corresponding to the callback function of the control service.

During the initialization of the controlled service, the terminal registers the callback function of the controlled service with the audio and video remote control protocol to obtain a second identifier corresponding to the callback function of the controlled service.

After the registration of the callback function is completed, the terminal will connect the audio and video remote control protocol.

The device connection process provided in the embodiment of the present application is further described below with reference to FIG. 4 and FIG. 5 .

The terminal obtains a control connection request sent by the target device for the audio and video remote control protocol, and obtains a first target service supported by the target device according to the control connection request.

If the first target service is the first controlled service, the terminal determines the control service as the second target service, and establishes a connection of an audio and video remote control protocol with the target device according to a callback function corresponding to the first identifier.

If the first target service is the first control service, the terminal determines the controlled service as the second target service, and establishes a connection of the audio and video remote control protocol with the target device according to the callback function corresponding to the second identifier.

If the first target service includes the first controlled service and the first control service, the startup state of the target application is determined. If the startup state of the target application is startup, the control service is determined as the second target service, and a connection of the audio and video remote control protocol is established with the target device according to the callback function corresponding to the first identifier. If the startup state of the target application is shutdown, the page displayed by the terminal at this time can be any interface or the default interface, and the transmission direction of the multimedia can be determined.

If the transmission direction is from the target device to the terminal, the terminal determines the control service as the second target service, and establishes an audio and video remote control protocol connection with the target device according to the callback function corresponding to the first identifier. If the transmission direction is from the terminal to the target device, the terminal determines the controlled service as the second target service, and establishes an audio and video remote control protocol connection with the target device according to the callback function corresponding to the second identifier.
