HE910 transmit during network registration

2 thoughts on “HE910 transmit during network registration

  1. After the HE910 module is powered on and AT+COPS is 0, does the module transmit anything if no suitable cell is found?

    When does the module transmit when it is searching for an operator to register to?

    1. If the module can’t find a suitable PLMN, it camps on one cell in emergency mode, and it doesn’t transmit anything.

      When it founds a suitable PLMN, it starts the registration procedure -> it sends a location update request to the network.
