I am testing with SL8084T module, when I type in AT+WDSC or AT+WDSS, I am getting Error.
I want to check whether AirVantage is enabled on this module, it is my first time of using this feature. I am sure it may not be enabled.
How do I enable it?
Thanks in advance
If you send at+cmee=1 to the unit prior to sending the other commands then it will give you a cause value back, if you get 655 then the credentials on the unit are broken/not present and the AV server will not be able to authenticate with it. There is no way to load new ones on (even with SWI it is next to impossible) this can only be done at the factory so the best way is to get a new unit.
If it’s authentication failed, is there a way to use AT command to get it right?
No effectively there is no way to resolve this through AT commands, the only solution is to get a new unit.
