Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, in the first embodiment of a Bluetooth one-to-many data transmission method of the present invention, the following steps are included: S1. Obtain the available Bluetooth devices corresponding to the master Bluetooth device, with the goal of obtaining multiple available Bluetooth devices bluetooth device. Specifically, when the Bluetooth device serves as the master Bluetooth device, it searches for all Bluetooth devices that currently meet the distance requirement, that is, are within the effective range according to the trigger instruction. All the bluetooth devices can be understood as available bluetooth devices corresponding to the master bluetooth device. That is, the available Bluetooth device can meet the connection requirements of the main Bluetooth device, such as signal strength, communication protocol, etc., can meet the connection requirements with the main Bluetooth device. It can be understood that all available Bluetooth devices corresponding to the current master Bluetooth device are not necessarily the devices that the master Bluetooth device needs to connect to. Therefore, the desired Bluetooth device can be selected from the available Bluetooth devices as the target Bluetooth device based on requirements.

S2. Generate a connection list including all target Bluetooth devices, and trigger the master Bluetooth device to sequentially establish connections with the target Bluetooth devices based on the connection list to obtain the slave Bluetooth devices corresponding to the master Bluetooth device. Specifically, a corresponding connection list is generated based on the obtained target Bluetooth devices, that is, all target Bluetooth devices that need to be connected can be obtained from the connection list. Based on the connection list, one-click triggering can be triggered to establish a connection between the master Bluetooth device and the target Bluetooth device. Wherein, when the target Bluetooth device establishes a connection with the master Bluetooth device, the target Bluetooth device corresponds to the slave Bluetooth device of the master Bluetooth device. In an embodiment, the specific bluetooth connection process may be that the master bluetooth device actively sends the key to the slave bluetooth device, and if the slave bluetooth device receives the key and resolves successfully and calls back to the master bluetooth device, the master bluetooth device actively sends the key to the slave bluetooth device. The bluetooth device sends the command to open the high-speed communication channel, and after receiving the command to open the high-speed communication channel from the master bluetooth device, the bluetooth device opens the high-speed communication channel according to the preset bluetooth communication protocol, and the master bluetooth device receives the high-speed communication channel fed back from the bluetooth device After opening the message, the connection step is officially completed. In an embodiment, the connection status of each target Bluetooth device can be reflected by the status of the connection list.

S3. Obtain the device attributes of the slave Bluetooth devices respectively, so as to obtain all executable jobs of the slave Bluetooth devices according to the device attributes of the slave Bluetooth devices. Specifically, after obtaining the slave bluetooth devices that establish a connection with the master bluetooth device, each slave bluetooth device is confirmed. Obtain the device attribute of each slave Bluetooth device, and determine the job tasks that the Bluetooth device can perform according to the device attribute to execute the job. That is to confirm what kind of device the connected slave Bluetooth device is and what kind of tasks it can be used to perform. For example, when the obtained slave bluetooth device is a printing device, then the executable jobs corresponding to the slave bluetooth device can be obtained as jobs such as copying and printing. When the obtained slave bluetooth device is an air conditioner, then it can be obtained that the executable tasks corresponding to the slave bluetooth device are temperature adjustment, wind speed adjustment and other tasks.

S4. Obtain the job instruction generated by the master Bluetooth device, identify the target job of the job instruction, and obtain the corresponding slave Bluetooth device as the target job device based on the target job and all executable jobs of the slave Bluetooth device, so that the target job device responds to the job command. Specifically, a job instruction is generated by the master Bluetooth device. The operation instruction is a control instruction used to control the action of the slave Bluetooth device, and the operation instruction can be identified to obtain what operation it is used to perform. For example, if the master Bluetooth device generates a print instruction, then the target job corresponding to the print instruction is a print job. The print job can be executed from all the bluetooth devices that can perform printing by searching for them. Through this process, the automatic identification of the master bluetooth device's operation instruction and corresponding data transmission can be realized, and the fast and accurate data transmission can be realized during the one-to-many bluetooth connection.

Optionally, in step S1, obtaining available Bluetooth devices corresponding to the master Bluetooth device; including: triggering the master Bluetooth device to start scanning to obtain Bluetooth broadcast data, and sending a scan request to the Bluetooth device corresponding to the Bluetooth broadcast data to The corresponding response data is obtained, and the bluetooth device that generates the response data is obtained as the available bluetooth device. Specifically, the master device starts scanning first, and the slave device continuously sends broadcasts to the surroundings. When the master device turns on the scan function, the master device can receive the broadcast sent by the slave device, and then the master device receives the broadcast sent by the slave device. The slave device sends a scan request. After the slave device receives the scan request sent by the master device, the slave device sends a scan response to the master device (including uuid, mac, name and other information of the slave device), and the master device receives the scan request sent by the slave device. After scanning the response, get the slave device information and display it in the list.

Optionally, in the inventive bluetooth one-to-many data transmission method, further comprising: acquiring the slave bluetooth device based on historical connection information of the master bluetooth device. Specifically, after the master bluetooth device is disconnected from the slave bluetooth device, it can save all the previously connected information to the built-in storage of each slave bluetooth device, and the master bluetooth device also records the information of all the slave bluetooth devices connected before . When the master bluetooth device enters the effective range covered by the signal of the slave bluetooth device again, the master bluetooth device actively sends broadcast data, and after the slave bluetooth device receives the broadcast data sent by the master bluetooth device, it feeds back the connection-related information previously stored by the slave bluetooth device to Master Bluetooth device, the master Bluetooth device automatically takes the slave Bluetooth device as the current target Bluetooth device according to the previously connected relevant information fed back from the slave Bluetooth device and parses the previously saved slave Bluetooth device connection information, and automatically completes the target Bluetooth device. Connect to get the slave Bluetooth device corresponding to the current master Bluetooth device. For example, automatically through the system algorithm, the connected Bluetooth device is automatically connected by default, the check box is checked by default, and the subsequent status is displayed as connected. If the check box of the new device that is not connected is not checked, the status shows that it is not connected. That is, in the connection list, for the slave Bluetooth devices that have been connected in history, it can directly modify the state of the connection list as the connection state.

Optionally, in step S2, obtaining the slave Bluetooth device corresponding to the master Bluetooth device includes: obtaining the connection status between the master Bluetooth device and the target Bluetooth device, and using the target Bluetooth device as the master Bluetooth device when the target Bluetooth device is successfully connected to the master Bluetooth device from the Bluetooth device. Specifically, not every selected target Bluetooth device can realize the connection with the main Bluetooth device, that is, the connection status between the target Bluetooth device and the main Bluetooth device can be judged, that is, only when the selected target Bluetooth device and the main Bluetooth device After the connection is established, the target Bluetooth device can be used as the slave Bluetooth device of the master Bluetooth device.

Optionally, as shown in Figure 2, in the inventive Bluetooth one-to-many data transmission method, it also includes: S21, monitoring the connection status between the slave Bluetooth device and the master Bluetooth device, and disconnecting the slave Bluetooth device from the master Bluetooth device , remove the slave bluetooth device, and execute step S3. Specifically, in the work of the master bluetooth device, monitor the connection status between the master bluetooth device and each slave bluetooth device. removed from the device. At this time, the executable job corresponding to the master Bluetooth device will also change, so as to avoid that some job instructions cannot reach the actual slave Bluetooth device, so that the task cannot actually be completed.

Optionally, in step S4, acquiring the corresponding slave Bluetooth device as the target job device based on the target job and all executable jobs of the slave Bluetooth device, further includes: when multiple corresponding slave Bluetooth devices are obtained based on the job instruction, According to the device information of multiple corresponding slave bluetooth devices, the best slave bluetooth device is obtained as the target operation device. Specifically, when one job instruction can correspond to multiple slave bluetooth devices, the device information of the multiple slave bluetooth devices can be judged, and the best slave bluetooth device can be selected to respond. For example, when the user terminal is connected to each printer, it first obtains the transmission characteristics of each slave Bluetooth device, and records and saves the information. Before the user terminal sends the data to be printed to the printer through the APP, it first matches the data information to be printed according to the previously saved transmission characteristics of the Bluetooth device, and selects the printer that meets the requirements as the best printer. For example, there are three slave device printers, which are used to print photos (A), documents (B), and receipts (C). The user terminal sends an instruction to print the document to A, B, and C. When A, B, and C receive the printing instruction, A and C feedback information to the user terminal that it is not suitable for printing the document, and do not proceed to the next step. up. The feedback information of the B command is sent to the user terminal to feedback that it is suitable for printing the document. After receiving the request from B, the user terminal takes the high-speed channel and sends the document to B in the form of a byte array. After B completely receives the document data, the printer prints out document.

In one embodiment, when the slave equipment includes air conditioners and refrigerators, the jobs executed by the corresponding job instructions are all temperature adjustment functions. At this time, the executable jobs are similar. Therefore, when generating executable jobs, it adds For equipment information, the generation of operation instructions also increases the instruction type corresponding to equipment information. When the mobile phone sends an instruction to adjust the temperature of the device to be controlled to both the air conditioner and the refrigerator, the Bluetooth slave modules in the air conditioner and refrigerator actively identify the type of the instruction. If it is an air conditioner, the air conditioner responds to the operation instruction. However, the refrigerator does not respond to the operation instruction because the instruction type identification does not correspond. For example, when the mobile phone is connected to air conditioner 1 (A), air conditioner 2 (B), refrigerator 3 (C) and refrigerator 4 (D), first obtain the types of A, B, C and D, for example, A returns Type=1 ,B returns Type=1, C returns Type=2, D returns Type=2 and saves it in the phone. When the user wants to control the temperature of the air conditioner in the shopping mall, he selects an instruction of Type=1 to control the air conditioner from the instruction set and sends the instruction to A, B, C, and D. After receiving the instruction, A and B judge whether to send it to Adjust the temperature for your own. After C and D receive the command, they judge that it is not sent to them, so they don’t process it.

Optionally, as shown in FIG. 3, the method in the inventive Bluetooth one-to-many data transmission method further includes: A1, obtaining historical connection information of the master Bluetooth device and currently available Bluetooth devices; Information and the currently available Bluetooth device to obtain the unavailable Bluetooth device corresponding to the historical connection information; A2. Obtain the relationship between the unavailable Bluetooth device and the available Bluetooth device, so as to obtain the The transfer device corresponding to the unavailable Bluetooth device; A3. The transfer device and the unavailable Bluetooth device are the slave Bluetooth devices of the master Bluetooth device, so that the unavailable Bluetooth device receives the corresponding Bluetooth device through the transfer device. job order. Specifically, if some historically connected devices, that is, some devices in the list of operating devices are not currently within the control range of the mobile phone, then these devices can be defined as unavailable Bluetooth devices.

For example, A (air conditioner 1), B (air conditioner 2), C (air conditioner 3), D (air conditioner 4), E (air conditioner 5), and F (air conditioner 6) have all been connected to mobile phones before, and their device attributes have been changed. Saved to the phone. When the mobile phone can only scan A (air conditioner 1), B (air conditioner 2), and C (air conditioner 3), then D (air conditioner 4), E (air conditioner 5), and F (air conditioner 6) are defined as the main For the unavailable device corresponding to the Bluetooth device, at this time, the available Bluetooth device such as A (air conditioner 1) can be used as the master device to start the scanning function, and after receiving the broadcast of the surrounding unavailable Bluetooth slave device, a scanning request is initiated, and the surrounding Bluetooth slave device is unavailable Give the scan response (including uuid, mac, name, rssi value, etc.)" to obtain the corresponding unavailable device, and use the signal strength of the RSSI value to determine whether it is the proxy of the unavailable device, that is, the transit device and establish a connection. For example, A The RSSI value of searching D is -45, the RSSI value of A searching E is -80, and the RSSI value of A searching F is -100, then A (air conditioner 1) is used as the agent of D (air conditioner 4), that is, the transit device. A( Air conditioner 1) establishes a connection with D (air conditioner 4). When A (air conditioner 1) receives the operation command, it forwards the command, such as turning off the air conditioner, to D (air conditioner 4). After receiving the command, D (air conditioner 4) Complete the action of turning off the air conditioner. B (air conditioner 2) starts the scanning function as the master device, and initiates a scan request after receiving the broadcast from the surrounding unavailable Bluetooth slave devices, and the surrounding unavailable Bluetooth slave devices give a scan response (including uuid, mac, name , rssi value, etc.)", and finally obtain the above-mentioned unavailable Bluetooth device, obtain the corresponding unavailable device through the signal strength of the RSSI value and act as the proxy of the unavailable device, that is, the transit device. For example (the RSSI value of B searching E is -45, the RSSI value of B searching D is -80, and the RSSI value of B searching F is -100), then B (air conditioner 2) acts as the agent of E (air conditioner 5), and B ( Air conditioner 2) establishes a connection with E (air conditioner 5), and when B (air conditioner 2) receives the operation command, it forwards the operation command to turn off the air conditioner sent by the mobile phone to E (air conditioner 5), and E (air conditioner 5) receives the command Complete the action of closing the air conditioner. C (air conditioner 3) starts the scan function as the master device, and initiates a scan request after receiving the broadcast from the surrounding unavailable Bluetooth slave devices, and the surrounding unavailable Bluetooth slave devices give a scan response (including uuid, mac, name, rssi value, etc.) "Finally get the above-mentioned unavailable Bluetooth device, obtain the corresponding unavailable device through the signal strength of the RSSI value and act as the proxy of the unavailable device, that is, the transit device. For example, C searches for the RSSI value of F -45, and C searches for D The RSSI value of C (air conditioner 3) is -80, the RSSI value of C searches for E is -100, then C (air conditioner 3) acts as the agent of F (air conditioner 6), C (air conditioner 3) and F (air conditioner 6) establish a connection, and forward the mobile phone The sent operation instruction to turn off the air conditioner is given to F (air conditioner 6), and F (air conditioner 6) completes the action of turning off the air conditioner after receiving the instruction.

It can be understood that when it is possible to obtain unavailable Bluetooth devices based on historical connection information and currently available Bluetooth devices, all currently available Bluetooth devices can be set to start the scanning function to scan their respective RSSI values relative to the part of the target operating device , and then transmit all the RSSI values back to the mobile phone for statistical analysis, and finally obtain the optimal transfer device corresponding to each unavailable Bluetooth device according to the signal strength of the RSSI value.

Optionally, if some unavailable Bluetooth devices cannot find the corresponding transfer device, you can define all the slave Bluetooth devices of the current master Bluetooth device as the currently available Bluetooth devices of the master Bluetooth device, and continue based on the new currently available Bluetooth devices Get the relay device for remaining unavailable bluetooth devices. Through this process, the search range can be expanded and the scanning function can be enhanced. That is, each time a new transfer device is obtained, it is judged whether there is still an unavailable Bluetooth device, and based on the judgment result, it is determined whether the transfer device needs to be acquired again until there is no unavailable Bluetooth device. The specific process can be as follows: the available Bluetooth devices within the effective scanning range of the mobile phone are used as the first-order scanning master device, so that all the first-order scanning master devices start the scanning function, and all devices scanned by the first-order scanning master device are called second-order scanning. Scan the main device, if there are still some target operating devices that are not in the list of the main devices of the second-level scan, let all the main devices of the second-level scan start the scanning function, and all the devices scanned by the main device of the second-level scan are called the master of the third-level scan If there are still some target operation devices that are not in the three-level scanning main device list, let all three-level scanning main devices start the scanning function, so as to exhaust the devices that can be scanned, and connect all target jobs as much as possible in this way equipment.

For example, the target operating equipment includes A, D, E, K, and M, and the available Bluetooth devices of the mobile phone are A, B, and C. According to the above, A, B, and C are the first-order scanning master devices, because D, E, and K , M is not in the first-order scanning master device, let the first-order scanning master device start the scanning function, the RSSI value when A scans to D is -70, the RSSI value when B scans to D is -40, and the RSSI value when B scans to E The RSSI value is -80, and the RSSI value from C to E is -30, so D and E devices are the master devices of the second-order scan. Because K and M are not in the second-order scanning master device, let the second-order scanning master device start the scanning function. When D scans to F, the RSSI value is -60, and when D scans to G, the RSSI value is -75. Therefore, F, G The device is a three-stage scanning master device. Because K and M are not in the third-order scanning master device, let the third-order scanning master device start the scanning function, the RSSI value from F scanning to H is -70, and the RSSI value from G scanning to H is -80, so H is fourth-order Scan for master devices. Because K and M are not in the fourth-order scanning master device, let the fourth-order scanning master device start the scanning function, and the RSSI value of K scanned by H is -45, so K device is the fifth-order scanning master device. Because M is not in the fifth-level scanning master device, let the fifth-level scanning master device start the scanning function, and the RSSI value of L scanned by K is -60, so L is the sixth-level scanning master device. Because M is not in the sixth-level scanning master device, the sixth-level scanning master device is allowed to start the scanning function, and because no connectable Bluetooth device is found within the effective scanning range of L, the execution of the enhanced scanning function is terminated. Return all the useful data obtained during the execution of the enhanced scan function to the mobile phone for processing. Valid data such as: (A->D:-70) means that A scans to D, and the RSSI value returned by D to A is -70 , the same as above. (B->D:-40), (B->E:-80), (C->E:-30), (D->F:-60), (D->G:-75), (F->H:-70), (H->K:-45), (K->L:-60), (L->M: cannot be scanned). After returning the above data to the mobile phone for processing, the optimal links of the target Bluetooth devices (D, E, K) that are not within the effective range of mobile phone scanning are obtained: (1) mobile phone -> B -> D, ( 2) mobile phone->C->E, (3) mobile phone->B->D->F->H->K, but since L cannot search for the target operating device M, even though M is the target operating device, the final The job instructions issued by the mobile phone cannot be executed, so (4) the link of mobile phone->B->D->F->H->K->L->M does not exist.

In the above (2), it can be obtained that C acts as the proxy of E's target operation device, that is, the transfer device, establishes a connection and forwards the operation instructions issued by the mobile phone to E, and E performs the actions related to the instructions as the target operation device.

In the above (1), it can be obtained that B acts as the agent of D’s target operation equipment, that is, the transfer equipment, establishes a connection and forwards the operation instructions issued by the mobile phone to D, and D performs the actions related to the instructions as the target operation equipment. According to the above (3 ), it can be known that B, D, F, H, as the agent of the K target operation equipment, that is, the transfer equipment, establish connections in turn, and forward the operation instructions issued by the mobile phone to the layer-by-layer transmission and finally reach the target operation equipment K, K as the target operation After the device receives the job instruction, it executes the actions related to the instruction. Finally, it is ensured that all unavailable Bluetooth devices within the effective connection range of the available Bluetooth devices find the corresponding available Bluetooth devices as agents, that is, the transfer device, and receive the job instructions that should be processed through the transfer device.

Optionally, as shown in FIG. 4 , in the Bluetooth one-to-many data transmission method of the present invention, it also includes: S5. Receive feedback information generated by the target operation device based on the operation instruction, so as to determine whether the target operation device is compatible with the operation according to the feedback information. The execution status of the instruction. Specifically, in order to ensure that the command set can be safely, quickly and accurately transmitted to the slave Bluetooth device, the command is passed through a special channel, which includes data encryption and decryption, and the fast channel protocol mechanism. In order to ensure that all executed slave Bluetooth devices can accurately execute the instructions issued by the master Bluetooth device, there is an error correction mechanism. When the slave bluetooth device receives an instruction from the master bluetooth device but fails to execute the corresponding action, it feeds back the execution failure result to the master bluetooth device. The master bluetooth device receives the failed result returned from the bluetooth device, and re-issues the command set to the slave bluetooth device, and so on. If the slave bluetooth device executes successfully within the specified number of times, it will feed back this message to the master bluetooth device. This operation is not complete until the device is installed. Otherwise, after exceeding the specified number of times, the master bluetooth device sends a restart command to the slave bluetooth device and saves the information in the database. After receiving the restart command from the Bluetooth device and restarting, disconnect. After the slave Bluetooth device restarts and connects to the master Bluetooth device, the master Bluetooth device sends the previous command again. If the message returned from the slave Bluetooth device to the master Bluetooth device still fails, the master Bluetooth device will display that the device is faulty and needs to be repaired. Such a reciprocating cycle, until all the slave Bluetooth devices have executed the instructions issued by the master Bluetooth device, the action is considered to be completed.

In a specific embodiment, the Bluetooth multi-connection application is opened in the mobile phone, referred to as A, and A is used to replace the Bluetooth multi-connection application in the following. Conditions: The master Bluetooth device is within the effective range of the signal coverage of the slave Bluetooth device, and the Bluetooth speaker, Bluetooth printer, Bluetooth curtain, Bluetooth access control, Bluetooth air conditioner, and Bluetooth ambient light are all powered on. Open the A application, and the A interface is based on the filter conditions , only scan the above six slave bluetooth devices that need to be displayed and check the slave bluetooth devices to be selected, and click one-click connection. After the selected slave Bluetooth device is successfully connected and the connected status information is displayed on the A interface, at this time, the A application in the master Bluetooth device can issue an instruction set to the slave Bluetooth device at the same time to control the Bluetooth speaker to start playing and pause Play, previous track, next track, etc. At the same time, send an instruction set to the slave Bluetooth device to control the Bluetooth printer to print documents, photos, etc. At the same time, the instruction set is sent to the slave Bluetooth device to control the opening and closing of the Bluetooth curtain. At the same time, the instruction set is issued to the slave Bluetooth device to control the opening and closing of the Bluetooth access control device. At the same time, the command set is issued to the slave Bluetooth device to control the Bluetooth air conditioner on and off, temperature adjustment, wind speed, scanning mode, etc. At the same time, the instruction set is sent to the slave Bluetooth device to control the Bluetooth ambient light on, off, color temperature adjustment, etc. If the A application of the master Bluetooth device sends corresponding instructions to the slave Bluetooth device, and the slave Bluetooth device returns an incorrect command, an error correction mechanism is triggered to ensure that the slave Bluetooth device can correctly execute the control command set issued by the master Bluetooth device. When the master bluetooth device leaves the effective range covered by the signal of the slave bluetooth device, it will automatically disconnect.

When the master bluetooth device reappears in the valid range covered by the slave bluetooth device information, it will automatically connect to the previously connected slave bluetooth device. In this way, the realization of Bluetooth one-to-many connection is realized, which greatly improves the quality of life of users. In a real sense, it realizes the automation function of one master Bluetooth device controlling multiple slave Bluetooth devices at the same time, which is more convenient.

In addition, as shown in 5, a Bluetooth one-to-many data transmission device of the present invention includes:
