BM (Bandmask) (LTE-M)

Note This command is for use with only LTE-M.

Configures the enabled 4G LTE bands for LTE-M when CP is set to 1 (No Profile).

Changes to the value only take effect on boot so a reboot or power cycle is required for any changes to become active.

Initial setup can take several minutes to complete, as the search for NB-IoT bands can take up to 210 seconds per band. Once made, the connections are remembered by the device, making subsequent startup times shorter.

Note The actual set of enabled bands will be a subset of this bit field, depending on the limitations of the cellular component.

WARNING! If this value is configured incorrectly, the XBee module may be unable to locate a tower and join the network.
