When trying to resolve a domain name with AT#QDNS I keep getting the error “operation not supported”.
If I use the domain name with AT#SD it will get resolved while opening the socket.
Below is the log of how I get to calling AT#QDNS. Do I have to set up anything else before being able to use this command?
at+cmee=2
OK
at+cpin=0000

at+creg?

There is a note at the #QDNS command description, are the conditions fulfilled?
This command is available only on the first AT instance (see AT#PORTCFG) or on the first virtual port of CMUX and works on the PDP context 1 and on the first ConnId ( see AT#SCFG ).
Ah yes, in my case PORTCFG=0. I switched to the UART interface and it worked.
Hi,
I am using a HE910-DG at firmware 12.00.006.
