Android 10 Compatibility

Start by reproducing the BlueVoice audio-streaming issue on Android 10 with the BVBNRG board, then inspect logcat around the descriptor-write error and repeated Bluetooth reconnection. Done means audio and waveform plotting continue without the connection entering the Dead state.

Hello,

I am running the ST BLE Sensor app V 4.7.1 on a Motorola Moto g7 Power that runs Android 10 (API 29). I am using the BVBNRG board.

I am having trouble using the BlueVoice portion of the app. After a few seconds, the audio data stops streaming and the waveform graph stops plotting. If I wait a few more seconds, the Bluetooth connection between the phone and BVBNRG board disconnects and reconnects (see log below). Upon reconnection, the audio stream resumes then stops again after a few seconds.

Is the ST BLE Sensor app compatible with Android 10? If so, what changes do I need to make to allow continuous audio stream with the BlueVoice fragment?

Thanks.
