'Raspberry Pi to SIM8200EA-M2_5G_HAT with audio jack
I am trying to make python based phone calls, using a raspberry pi (4) and a waveshare SIM8200EA-M2_5G_HAT. The first part was easy: find the AT commands to send over serial interface to start/stop the call.
Next step was supposed to be playing an audio file. Python to play an audio file was easy peasy. Sound came out to the audio jack of the pie. Before I think about the final solution to wire pi to HAT, I used the same earphone (phones and mic) to directly connect to the HAT. A started call (using minicom) did not provide any sound. Neither could I use the microphone nor did I hear anything from the call.
Is anyone familiar with this setup - or at least the HAT - and know about the pain to make the audio jack working?
