BM64 mic sound poor
Good afternoon, engineers :)
In the BT headset based on the module BM64, the sound quality from the microphone of the headset is very poor. Of course I listen to the sound on the phone I'm calling to.
When switching from the headset to the microphone of the phone, the sound is much better.
If connect a microphone to the amplifier and listen to it separately, the sound is also good.
Can anyone come across this problem?
Connection scheme as in a datasheet and microphone too. Something is wrong in the DSP settings.
