I’m trying to transfer data using voice call. I would like to send ascii char (mapped into
PCM sample) from one modem to another.
Therefore, I need to record PCM stream using adl_audiostreamlisten function.
I started from pcm_record_play sample but I noted that Low Irq handler is not called
(where the receiving buffer is written).
Only High Irq handler is called and the resulting buffer is empty.
I search in the forum and some guys seem to success in recording PCM stream but I
can’t understand how this function and irq work.
Does anyone has expirence on this matter?
