Hi ninora !, thanks for your help. Yes, I had being reading those ones and others...but sincerely I can't find something specific for that board.
I'm trying different setups...using FONA Library examples, now I can read board information, but RSSI shows
RSSI = 99: -115 dBm
and
Network status "n" shows
---> AT+CREG?
<--- +CREG: 0,0
-> Network status 0: Not registered
Kind regards,
Ed.
