i already showed it in another topic but thought this is worth its own

I built a SIM800L module (incl speaker and mic) into the OGA. Thanks to the plenty of space inside the case it was pretty easy. In theorie i would have an Odroid Go Advance cell phone now


I have troubles talking to it.
It is connected to the UART2 CON3 port on the right side.
As image i use debian buster
Can someone help me how to talk to the port? I tried with minicom on address ttyFIQ0 (thanks to mad_ady i know the address

I would really appreciate any help to get a first „OK“ from the module after sending „AT“ to it


Thanks so much and i hope we get that cell phone working
