Hi,
Using a 2G Sim (Orange operator, in France), I succeeded calling the EG915U module (I saw the “RING” pin changing).
But with a 4G SIM (also Orange operator), the “RING” pin does not change (neither after AT+QCFG=“nwscanmode”,1,1 nor after AT+QCFG=“nwscanmode”,3,1) .
Nevertheless,
- Putting the 4G SIM in a phone, I can call it : the phone rings.
- From the EG915U module, using this 4G SIM, I can send data using GPRS ; I can also send SMS.
Module firmware is: EG915UEUABR02A04M08
Any idea ?
Thanks.
