I'm trying to use my Bluetooth microphone with Raspberry Pi 3 (using BCM43438), but it seems that the chipset or its firmware are NOK
Using external Bluetooth dongle solve the proble.
so I'm looking for any documentation or driver for BCM4343B to test it.
We don't support Raspberry Pi,
We request you to move to raspberry pi forum as it is custom specific query.
we can provide you datasheet for BCM43438
Thanks & Regards,
