We are working with IMX8QM MEK board, running on Android 9  automotive and interfaced M.2 module which has CYW4356 chipset.  It uses BCM4354A2.1CX.hcd firmware.

After interfacing this module we came to know that HFP audio is not working , we could only hear the noise. But A2DP and AVRCP, PBAP are working fine.

We want to know default I2C and PCM settings which are done as the part of this firmware.

1) Could you please let us know these parameters ?

2) Also we would like to know if there are any commands or tool which we use to change bluetooth PCM settings.

 

We would like to generate CYW4356 BT firmware for IMX*QM MEK board. Please help here
