I have two issues with testing BG95-M3 (Eval board).
First problem I have with CMW 500, I cannot connect with CMW with any service (GSM 900, 1800 (CS, PS-EGPRS, LTE CatM1, NB-IoT). Configuration must be correct because I can connect with another Mobile Stations (various mobile phones, I don’t have IoT device). CMWs SIM card is read correctly but if I request AT+COPS I cannot see any operator.
Is there any white paper or application note for CMW500 testing?
Another problem I have with commercial polish operators. With some SIM cards I’m able connect to BTS with GSM-CS, with some I’m not. Does anyone report similar problem?
