Hi,

We are using M66 module for audio transfer with PCM module. M66 was set as master and stm32 was set as slave for PCM our system. And the system is working well.

We want using anymore BG95-M3 Module for audio transfer. But it is not explained well enough in your document. is it possible to use Bg95-M3 like M66? Or else what is the best way to use PCM with STM32 or other mcu types?

sorry ，
I have to say ， the PCM interface used for volte only ， it can not be used to connect MCU PCM
interface as Audio channel

When the BG95 channel has been use ， it can be used to connect codec only for volte functions。
