However I try, I cannot set the AT Run config command, keep getting "operation not allowed". Is there something that I’m missing? AT Command Reference doesn’t say anything about it.
AT#TCPATRUNCFG=2,3,1024,1024,""+CME ERROR: operation not allowed
Is the context opened prior to do the configuration? You have to configure the firewall and auth params as well for server mode.
I need to close AT Run itself to change these parameters.
Now it works. But these pre-conditions could be more clearly stated in the AT Reference.
