Automatic RRC connection request

IoT Modules MC/EM Series
1

Is there any way to configure the RRC Connection request behavior on EM7455?
I am able to query the status via “AT!GSTATUS?” but unable to find any configuration option.
How do I make sure that EM7455 sends RRC Connection request automatically?

AT!GSTATUS?

Whenever there is a data traffic coming or from the cellular interface through the module, RRC connection will be established automatically.

RRC Connection is not getting established automatically in one of the setup with Verizon Sim.
Is there any way to debug this?

Do you know if you have the correct APN for data connection for the given Verizon SIM? What do you get from the following AT command?

  • ATI
  • AT!GSTATUS?
  • AT+CGDCONT?
  • AT+CGCONTRDP
