Detailed Description

Before describing the embodiments of the present application, a description will be given first of the related art.

Along with the gradual maturity of bluetooth technology, bluetooth equipment's kind is more and more including bluetooth headset, bluetooth speaker, on-vehicle bluetooth etc. simultaneously, user connects and uses bluetooth equipment to carry out the scene of media service also more and more abundant, like connect the phone call, use all kinds of video applications to watch the video, use all kinds of audio applications to listen to music, use all kinds of social applications to play voice message, use navigation application to accomplish route navigation etc.. In the above usage scenario, the user often finds that after the main device establishes a bluetooth connection with the bluetooth device, when the audio/video in the main device starts playing, the bluetooth device cannot sound synchronously, but has a delay of several seconds. This results in an inferior user experience.

The present application has been made to solve the above-mentioned problems.

Through the research on the above problems, in the bluetooth technical field, there are four connection modes of the main device and the bluetooth device in the bluetooth connection state, including an active mode (active mode), a breathing mode (sniff mode), a hold mode (hold mode), and a sleep mode (park mode).

In the active mode, the bluetooth device monitors the data packet sent from the main device side at all times. The data transmission efficiency is highest and the power consumption is also highest in the connection mode.

In the breathing mode, the master device negotiates a data transmission time slot with the Bluetooth device, and the Bluetooth device monitors a data packet sent from the master device side according to the time slot which is well in protocol with the master device. The data transmission efficiency in the connection mode is lower, but the power consumption of the device can be reduced.

In the hold mode, the master device negotiates the hold period with the Bluetooth device, and the data packet receiving and transmitting is not supported in the hold mode, so that the power consumption is saved.

In the sleep mode, data transmission and reception are stopped between the main equipment and the Bluetooth equipment, so that the power consumption can be saved to the greatest extent.

In the prior art, after the main device is connected with the bluetooth device, if the user does not play audio and video for a long time, the main device does not need to send a media stream to the bluetooth device, so as to save the power consumption of the device, and the main device enters a breathing mode. In the breathing mode, if the user resumes playing the audio-visual data, the master device detects that a corresponding media stream is generated and exits the breathing mode. Therefore, in the current technical scheme, when the user at the main equipment side resumes playing the audio and video, the main equipment and the bluetooth equipment are still in the breathing mode. However, because the response speed of the bluetooth device side to the media data packet of the main device side is slower in the breathing mode, the problem that the audio and video of the main device starts to play and the sound of the bluetooth device side is slow can occur.

In the application, a first Bluetooth device and a first electronic device can be provided. The first bluetooth device may be any bluetooth device, such as a bluetooth headset, a bluetooth speaker, and an onboard bluetooth device. The first electronic device may be any electronic device capable of establishing a bluetooth connection with a bluetooth device. The first electronic device may be, for example, a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), or the like, and the specific type of the first electronic device is not limited in the embodiments of the present application.

The application provides a Bluetooth control method which is applied to first electronic equipment, and particularly can be applied to a Bluetooth module of the first electronic equipment. The first electronic equipment provided by the application can monitor the foreground application switching condition of the local equipment under the condition that Bluetooth connection is established with the first Bluetooth equipment and the first electronic equipment is in a breathing mode. And when the foreground application is detected to be switched into the pre-designated target playing application, the breathing mode is exited, and the activation mode is entered. Based on the technical scheme of the application, when a user enters the target playing application interface and playing of the audio and video is not started, the user immediately exits from the breathing mode and enters into the activation mode. After entering the active mode, the first bluetooth device may high-frequency monitor the media stream sent by the first electronic device. Based on the above, when the user starts to play the audio and video on the first electronic equipment side, the first Bluetooth equipment can realize synchronous play, thereby preventing the play delay of the first Bluetooth equipment side and improving the user experience.

For easy understanding, the following embodiment of the present application will take a first electronic device having a structure shown in fig. 1 as an example, and describes a bluetooth control method provided by the embodiment of the present application. The bluetooth control method provided by the embodiment of the application can be executed in the first electronic device, and can be specifically executed in a bluetooth module of the first electronic device.

Fig. 2 is a schematic flowchart of a bluetooth control method according to an embodiment of the present application. As shown in fig. 2, the bluetooth control method provided by the embodiment of the application includes:

101, a first electronic device establishes a bluetooth connection with a first bluetooth device.

102, the first electronic device determines that it is currently in a first connection mode.

103, the first electronic device monitors the switching condition of the foreground application.

104, the first electronic device detects that the foreground application is switched to the target application.

105, the first electronic device enters a second connection mode.

In the embodiment of the application, when the first electronic device and the first Bluetooth device are in the Bluetooth connection state and in the first connection mode, the Bluetooth module of the first electronic device can monitor the switching condition of the foreground application. Wherein the first connection mode may be a breathing mode. The switching condition of the foreground application may specifically include whether the foreground application is switched or not, and the foreground application after the switching. The switching condition of the foreground application can reflect the application interface where the user is currently staying. For example, if the foreground application switches to the first application, then it may be determined that the user is currently staying at the application interface of the first application.

Based on the above description, when the bluetooth module of the first electronic device detects that the foreground application is switched to the target application, it may be determined that the user is currently staying at the application interface of the target application, and at this time, the first electronic device may exit the first connection mode and may enter the second connection mode.

In the application, the target application is at least one pre-designated application with an audio/video playing function. Examples may include, but are not limited to: various video applications, various short video applications, various audio applications, various social applications, various navigation applications, conversation applications, and the like. The second connection mode may be an active mode. In the second connection mode, the response frequency of the first Bluetooth device to the data packet sent by the first electronic device is higher than that of the first connection mode.

When the user switches to the application interface of the target application, the user can be considered to have a high probability of playing the audio and video immediately, and the user exits the first connection mode and enters the second connection mode, so that the response speed of the first Bluetooth device side to the media stream is improved after the user starts playing the audio and video, the playing time delay of the first Bluetooth device is reduced, the slow sounding condition is improved, and the user experience is improved.

It will be appreciated that in the second connection mode, the data transfer between the first electronic device and the first bluetooth device is more efficient, but the device power consumption is greater. Therefore, after the data transmission requirement disappears, the first electronic device needs to timely exit the second connection mode and reenter the first connection mode.

In another embodiment of the present application, an implementation manner of the first electronic device reentering the first connection mode in the second connection mode is described.

Fig. 3 is another schematic flowchart of a bluetooth control method according to an embodiment of the present application. As shown in fig. 3, after the first electronic device enters the second connection mode, the bluetooth control method provided in the embodiment of the present application may further include:

the first electronic device detects 201 whether there is a media stream to be transmitted. If not, then step 202 is performed; otherwise, step 201 is continued.

202, the first electronic device determines whether to reproduce the media stream to be transmitted within a preset duration. If not, execute step 203; otherwise, step 201 is continued.

203, the first electronic device exits the second connection mode and reenters the first connection mode.

In the embodiment of the application, after entering the second connection mode, the first electronic device can detect whether the media stream to be sent is generated or not according to the set period. In an embodiment of the present application, the media stream to be transmitted may be a media stream based on a high quality audio distribution protocol (Advanced Audio Distribution Profile, A2 DP). If the media stream to be transmitted is detected, the current second connection mode is kept unchanged, and the media stream generation state is continuously detected. When a media stream is detected to be free of transmission, step 202 is performed to further determine the duration of the no media stream state.

Specifically, in step 202, the first electronic device may start a target Timer, where the timing duration of the target Timer may be set according to the requirement, for example, may be X seconds. Furthermore, the first electronic device may detect whether a media stream to be transmitted is generated within a time duration of the target timer. If the media stream to be transmitted is not generated all the time, the user can be considered to have no requirement of playing the audio and video by using the Bluetooth device, so that the first electronic device can exit the second connection mode and reenter the first connection mode, and the power consumption of the device can be saved.

In yet another embodiment of the present application, another implementation manner of the first electronic device reentering the first connection mode in the second connection mode is described.

Fig. 4 is another schematic flowchart of a bluetooth control method according to an embodiment of the present application. As shown in fig. 4, after the first electronic device enters the second connection mode, the bluetooth control method provided in the embodiment of the present application may further include:

301, the first electronic device detects a use state of a target application.

302, the first electronic device detects that a target application exits the foreground.

303, the first electronic device detects whether there is a media stream to be transmitted. If not, then step 304 is performed; otherwise, step 303 is continued.

304, the first electronic device exits the second connection mode and reenters the first connection mode.

In the embodiment of the application, after the first electronic device enters the second connection mode, the first electronic device can monitor the service condition of the foreground target application. If the target application is detected to exit the foreground, the user may be considered to have exited the application interface of the target application at this time. Then it can be immediately detected whether there is still a media stream to be sent.

If the media stream to be sent is detected to still exist, the background still plays the audio and video although the user exits the application interface of the target application. At this point, the current second connection mode may be maintained and the media stream state continues to be detected. And when the fact that the media stream to be sent does not exist is detected, the fact that the user exits the application interface of the target application and the playing of the audio and video by using the target application is stopped is indicated. At this time, the second connection mode may be exited and the first connection mode may be re-entered, thereby saving power consumption of the device.

According to the technical scheme, under the second connection mode, the first electronic equipment is controlled to reenter the first connection mode from the second connection mode based on the triggering conditions of the application state and the media stream state, so that the equipment power consumption can be better saved.

Fig. 5 shows another schematic structural diagram of the first electronic device 100 according to an embodiment of the present application. As shown in fig. 5, the first electronic device 100 provided in the embodiment of the present application may include a listening module 1001, a bluetooth module 1002, and a bluetooth chip 1003. The listening module 1001 may be located in an application framework layer of the first electronic device 100, the bluetooth module 1002 may be located in a system library of the first electronic device 100, and the bluetooth chip 1003 may be a hardware entity.

Based on the block diagram shown in fig. 5, fig. 6 shows another schematic flowchart of the bluetooth control method according to the embodiment of the present application. As shown in fig. 6, the bluetooth control method provided by the embodiment of the application includes:

the bluetooth module determines 401 that it is in a first connection mode with a first bluetooth device.

The listening module identifies 402 whether a foreground application is switched. If a handoff occurs, go to step 403; otherwise, step 402 is continued.

403, the monitoring module sends a first notification message to the bluetooth module.

And 404, the Bluetooth module determines the switched foreground application as the target application according to the first notification message.

In the embodiment of the application, the monitoring module can monitor the use condition of each application in the first electronic equipment. When the monitoring module recognizes that the foreground application is switched, the switching condition of the foreground application can be pushed to the Bluetooth module. Specifically, the monitoring module may send a first notification message to the bluetooth module, so as to push the switching condition of the foreground application to the bluetooth module.

In one possible implementation manner, the first notification message may carry a prompt message for switching the foreground application and identification information of the foreground application after switching. The identification information may be, for example, an application name, or any identification code or the like having a mapping relation with the application name in advance.

In this implementation, after the bluetooth module receives the first notification message, the bluetooth module may acquire the first identification information of the foreground application after the handover. Further, the bluetooth module may identify the first identification information to determine whether the switched foreground application is the target application.

In the embodiment of the present application, the target application may be any one or more applications with audio/video playing functions, and the types of the target application may include, but are not limited to: video applications, audio applications, social applications, navigation applications, conversation applications, etc. Specifically, the configuration file configuration can be preset. Specifically, a configuration file may be pre-established, and identification information of at least one target application may be stored in the configuration file. The identification information may be, for example, an application name, or an identification code associated with the application name, or the like.

Based on the above description, after the bluetooth module obtains the first identification information, the bluetooth module may obtain the configuration file, and compare the first identification information with the identification information of each target application pre-stored in the configuration file. And under the condition that the first identification information is consistent with the identification information of any target application in the configuration file, determining the switched foreground application as the target application.

In another possible implementation manner, the first notification message may carry a prompt message that the foreground application is switched to the target application.

In this implementation manner, when the monitoring module monitors that the foreground application is switched, the monitoring module may determine first identification information of the foreground application after the switching. Then, the monitoring module can acquire the configuration file, and compares the first identification information with the identification information of each target application pre-stored in the configuration file. And under the condition that the first identification information is consistent with the identification information of any target application in the configuration file, the monitoring module can determine that the switched foreground application is the target application. At this time, the listening module may send a first notification message to the bluetooth module, where the first notification message may be used to instruct the foreground application to switch to the target application.

Based on this implementation, the bluetooth module may directly determine the switched foreground application as the target application after receiving the first notification message, without having to perform more operations.

And 405, the Bluetooth module sends a first indication message to the Bluetooth chip.

406, the bluetooth chip exits the first connection mode and enters the second connection mode in response to the first indication message.

In the case that the switched foreground application is the target application, the user can be considered to be currently browsing the application interface of the target application. Because the target application belongs to the playing application, the user can be judged that the playing of the audio and video is about to occur in the subsequent use process. Therefore, the bluetooth module may send a first indication message to the bluetooth chip, where the first indication message may be used to instruct the bluetooth chip to exit the current first connection mode and enter the second connection mode. The specific manner and process of the bluetooth chip exiting the first connection mode and entering the second connection mode may refer to the prior art, and the disclosure is not repeated herein.

In contrast, in the case that the switched foreground application is a non-target application, it can be judged that the user has a high probability of not playing audio and video in the subsequent use process, and then the current first connection mode can be kept unchanged, so that the power consumption of the device is saved. Meanwhile, the monitoring module can continuously identify the switching condition of the foreground application.

According to the technical scheme, the Bluetooth module can monitor the switching condition of the foreground application through the monitoring module, and after the foreground application is identified to be switched into the target playing application, the Bluetooth chip is informed to exit the first connection mode and enter the second connection mode. Because the data transmission frequency between the first electronic equipment and the first Bluetooth equipment in the second connection mode is higher than that in the first connection mode, after the second connection mode is switched, the first Bluetooth equipment can quickly respond to the media stream subsequently sent by the first electronic equipment, so that the playing time delay of the Bluetooth equipment is reduced, and the problem that the Bluetooth equipment sounds slowly is solved.

Further, as shown in fig. 6, after the bluetooth module controls the bluetooth chip to exit the first connection mode and enter the second connection mode, the bluetooth control method provided by the embodiment of the application further includes:

407, the listening module identifies whether the target application exits the foreground. If the target application exits the foreground, execute step 408; otherwise, execution continues 407.

408, the listening module sends a second notification message to the bluetooth module.

409, the bluetooth module determines, according to the second notification message, that the target application exits the foreground.

The bluetooth module detects 410 whether a media stream is currently still to be transmitted. If there is no media stream to be transmitted, step 414 is performed; otherwise, step 410 is continued.

In a possible implementation manner, the first electronic device may further include an audio module, and the bluetooth module may implement monitoring of the media stream based on the audio module. Specifically, the audio module may detect whether a media stream to be transmitted is currently generated, and after determining that there is a media stream to be transmitted, the audio module may transmit a third notification message to the bluetooth module.

414, the bluetooth module sends the second indication information to the bluetooth chip.

415, the bluetooth chip exits the second connection mode according to the second indication information and reenters the first connection mode.

In the above implementation scheme, the current service state of the target application can be detected, and if the target application exits the foreground, whether a media stream to be sent exists currently can be detected, and if the media stream to be sent does not exist currently, the switching from the second connection mode to the first connection mode can be immediately performed. Based on the implementation manner, the scene that the user exits from the application interface of the target application and stops playing the audio and video by using the target application can be identified, and the first connection mode is cut in time under the scene, so that the power consumption of the equipment is saved.

In parallel with the implementation manners of the steps 407 to 410, after the bluetooth module controls the bluetooth chip to exit the first connection mode and enter the second connection mode, the bluetooth control method provided by the embodiment of the application further includes:

411, the bluetooth module detects whether there is a media stream to be transmitted. If there is no media stream to be transmitted, step 412 is performed; otherwise, execution continues with step 411.

412, the bluetooth module starts a target timer.

413, the bluetooth module detects whether a media stream to be transmitted is generated within the timing duration of the target timer. If there is no media stream to be transmitted, step 414 is performed; otherwise, execution continues with step 411.

In this implementation, the state of the media stream may be detected, and after the media stream to be sent is detected and the duration of such state reaches the preset duration threshold, the switching from the second connection mode to the first connection mode may be performed. The value of the preset duration threshold can be flexibly set based on scene requirements. Based on the implementation manner, a scene that the user does not exit the application interface of the target application but stops playing the audio and video by using the target application can be identified, and the first connection mode is cut in time under the scene, so that the power consumption of the equipment is saved.
