Dear support team,
I’d like to use the BC127 (Melody 6.1.5) in a Bluetooth Headset like application and need to integrate a Mic Mute function while a call is active.
Of course I could use an external analog switch or something to disconnect the microphone from the analog input. But a nicer way would be to do this directly in the BC127 module.
I already tried to set AUDIO=1 0 to switch temporary the the digital input, which is not used in my application. Also I tried to set AUDIO_ANALOG=0 15 1 OFF. But changing these parameters seems to be ignored while a call is already active. The changes take effect after the call state is idle again.
Is there a way to mute and unmute the analog input while a call is active?
