HL8548 Send pre-generated .wav file and Record it

Hi Everyone,

I need to send a pre-generated .wav file (or any format, I will convert it) from one module and record it on another module (into some file format) in order to see how the GSM channel reacts to the pre-generated audio.

Is there any way to get this done.
