When I set the operator with AT+COPS=1 (manual operator selection), CME ERROR: 30 is returned.
The NETLIGHT LED is off longer than it is on, so it is not connected to a carrier (network searching).
When I send AT+COPS?, I cannot get the operator.
However, when I send AT+QNWINFO, the specified operator with AT+COPS=1 is returned.
Question:
Are there differences between the operators that can be obtained with AT+COPS? and AT+QNWINFO?
I have checked the operation of each, and it seems to work as follows.
- With AT+COPS?, you can get the operator only if BG96 is connected.
- With AT+QNWINFO, you can get the operator that is trying to connect, regardless of whether BG96 is connected or not.
