Unresponsive cellular component in Bypass mode

When in Bypass mode, the XBee 3 Cellular LTE-M/NB-IoT does not automatically reset or reboot the cellular component if it becomes unresponsive.

Condition

In Bypass mode, the XBee 3 Cellular LTE-M/NB-IoT does not respond to commands.

Solution

  1. Query the AI (Association Indication) parameter to determine whether the cellular component is connected to the XBee 3 Cellular LTE-M/NB-IoT software. If AI is 0x2F, Bypass mode should work. If not, look at the status codes in AI (Association Indication) for guidance.
  2. Ensure that you set DO (Device Options) bit 3 to 0 before entering Bypass mode.
  3. You can send the !R (Modem Reset) command to reset only the cellular component.
