Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.
The technical conception of the application is as follows: and the working state of the Bluetooth playing device before disconnection is recorded, so that whether the Bluetooth playing device plays music before disconnection is known, if yes, the Bluetooth playing device is controlled to continuously play the previous music by sending a playing command, and the problem of audio playing interruption caused by abnormal restarting and disconnection is solved.
Fig. 1 is a schematic flowchart of a method for restarting a bluetooth playback device according to an embodiment of the present application. As shown in fig. 1, a method for restarting a bluetooth playback device includes:
step S110, according to the working state of the Bluetooth playing device, setting the value of the state flag bit and storing. The status flag bit does not disappear in the restarting process so as to record the working status of the Bluetooth playing device before playing.
Step S120, after the Bluetooth playing device is restarted to establish the Bluetooth connection, the stored state flag bit is detected, and the working state of the Bluetooth playing device before disconnection is judged, so that the follow-up playing control processing is facilitated.
Step S130, if the blue tooth earphone is in the audio playing state before being disconnected, a playing command is sent to enable the Bluetooth playing device to continue playing the previous audio.
Therefore, the working state of the Bluetooth playing device before disconnection is recorded through the state flag bit, and after the Bluetooth connection is restarted, the music playing function of the Bluetooth playing device is controlled according to the state information, so that the automatic continuous playing of music after restarting and reconnecting can be realized, the manual playing operation of a user under the abnormal restarting condition of the device is omitted, the automatic recovery of the music function of the Bluetooth playing device is realized, and the use experience of the user is effectively improved.
In an embodiment of the present application, in the step 130, the sent play command is an AVRCP play command, or may be another custom type play command, so as to inform the audio source end (such as the mobile phone end) to resume playing music.
Taking AVRCP playing command as an example, AVRCP (Audio/Video Remote Control Profile), i.e. Audio/video remote control specification, can realize control of media playing, and in a connection state, the bluetooth playing device can send AVRCP command to an Audio source end (such as a mobile phone) to control music playing and pausing. However, in the existing video or game scenario, after the bluetooth playback device is restarted and connected back, the A2DP (Advanced Audio Distribution Profile, bluetooth audio transmission model protocol) service is re-established, so that the audio playback is switched from the source device side to the bluetooth playback device side. Therefore, if the bluetooth playing device is in a video or game scene, sending a playing command triggers some source device terminals to synchronously play music, so that the sound of the video or game is mixed with the sound of the music, and the use experience of a user is affected.
Thus, in step S130, after determining that the blue tooth earphone is in the audio playing state before being disconnected, the present embodiment further includes the following steps: further judging whether the Bluetooth playing device is in a service state of the music player before disconnection, if yes, sending a playing command, otherwise, not sending the playing command.
In one embodiment of the present application, further determining whether the bluetooth playing device is in a service state of the music player before disconnection includes:
detecting whether the Bluetooth playing device generates an A2DP audio stream after restarting to establish Bluetooth connection, if the A2DP audio stream does not generate, judging that the Bluetooth playing device is in a service state of a music player before disconnection, and if the A2DP audio stream generates, judging that the Bluetooth playing device is in a service state of a non-music player before disconnection.
Because the Bluetooth playing device is restarted to be connected back after being disconnected in the prior video or game scene, the A2DP service can be re-established, so that the Bluetooth playing device generates an A2DP audio stream, and whether the Bluetooth playing device is in a service state of a music player for simply playing music before being disconnected can be judged by detecting whether the Bluetooth playing device A2DP audio stream is connected back or not, thereby avoiding the situation that the music playing is triggered by mistake due to the fact that a playing command is sent, and affecting the video watching and game experience of a user.
In an embodiment of the present application, in the step 110, setting and saving the value of the status flag according to the working state of the bluetooth playing device includes: when the Bluetooth playing device plays the sound, the sound playing time is timed, if the playing time exceeds the preset duration, the state flag bit is set, and when the sound playing is stopped, the state flag bit is reset. According to the sound playing duration, the working state of the Bluetooth playing device is judged, so that the fact that prompt tones such as short messages, apps (Application programs) and the like are mistakenly considered to be music playing can be avoided.
In one embodiment of the present application, the status flag is an A2DP flag newly written into the bluetooth playing device, and the A2DP flag is not reset in the process of restarting without power failure, so that the status flag can be used continuously after abnormal restarting.
Fig. 2 shows a workflow of restarting a bluetooth playback apparatus according to an embodiment of the present application, where the bluetooth playback device is a bluetooth headset.
As shown in the left side of fig. 2, in the normal playing state, the status flag bit A2DP bootmode is set according to the duration of playing sound, when the playing duration exceeds the preset duration (for example, 2 seconds), it is determined that music playing exists at this time, the flag bit of the A2DP bootmode is set, and if the playing duration does not exceed the preset duration (for example, 2 seconds), the flag bit of the A2DP bootmode is reset when the playing of the sound is stopped. The A2DP bootmode flag bit is restarted without resetting, so that the Bluetooth headset can be reserved for use after restarting when the Bluetooth headset is abnormally restarted.
As shown in the right side of fig. 2, after the earphone is restarted and connected back, it is first determined whether the A2DP bootmode flag bit is in a set state. If not, the earphone is considered to play no audio before being disconnected, and processing is not needed. If yes, continuing to judge whether the A2DP audio stream exists after the earphone is connected back. If yes, the earphone is indicated to be in a non-music player service before disconnection, for example, in a service such as a video service, a game service and the like, at this time, recovery control of music playing is not needed, if no A2DP audio stream exists after the earphone is connected back, the earphone is indicated to be in a music player service before disconnection, at this time, a playing command is sent, and an accurate music continuous playing function can be achieved.
By integrating the description of fig. 2, the embodiment realizes the reply of the music playing service after the bluetooth playing device is restarted and is connected, and filters the interference of short-time sound playing such as prompt tone and the interference of multimedia services such as video, games and the like, thereby obviously improving the user experience.
