I am using EP06-A (version: EP06ALAR02A08M4G).
I am having issues with ‘AT+COPS=?’ failing after successful registration/connection/activation with a returned ‘CME ERROR: 3’ even though other network cmds like ‘AT+COPS?’, ‘AT+QNWINFO’, ‘AT+CREG?’, ‘AT+CEREG?’, ‘AT+CGREG?’, ‘AT+QENG=“servingcell”’, ‘AT+CGATT?’, etc. all return responses that show a successful network connection and activated PDP session.
I’ve tried to use qmicli -d <path to device> --nas-network-scan
and that eventually fails with an abort
message.
Are there any known issues with this AT command on this firmware version?
