B-L462E-CELL1 Audio

[TLans.1]

I want to build an IoT audio device and I am trying to operate the audio option on the B-L462E-CELL1. Unfortunately, there is a note saying that audio option is not available on the LBAD0ZZ1SE module on that board.

Is there a way to work with the audio codec on that board?

p.s. I also tried to contact Murata with this question. Still didn't get an answer.

Thanks.

Hello,

The Audio codec on this board is mainly used for Voice communication over cellular such as VoLTE or VoIP. The audio codec is controlled by the Modem FW. The default Modem FW does not support any voice feature that's it is said that audio is not supported.
If your goal is to enable the voice feature there is a need to setup dedicated project.

Thanks

We want to write our own code on the MCU (STM32L462REY6TR) to read data from the audio codec (the on board MAX9867). Is that possible?

It seems that we can't access I2C0 which is the port that is connected to the MAX9867. According to the LBAD0ZZ1SE datasheet, I2C0 and PCM pins are not implemented. Is that so?

You wrote that we need to 'setup dedicated project'. Can you please explain?

Thanks in advance.
