Is there anyone who has actualy connected with an IoT network? I'm trying to follow the steps for the R410M (T-Mobile commands for SARA R410M) but I'm not sure if that's working.
There also seems to be no new firmware for the R412M?
Commands from AT commands like:
All return with ERROR
When I follow the commands from the T-Mobile example all is going well till:
AT+COPS=1,2,"20416" Sometimes CME ERROR: SIM failure
AT+CGPADDR (I never get an address)
