Digi XBee® 3 Cellular LTE-M/NB-IoT Global Smart Modem User Guide 189
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.
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.
Parameter range
0 - 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF (bit field)
Example: 0x080080 (bits 7 and 19) enable LTE Bands 8 and 20.

BN (Bandmask) (NB-IoT)
Note This command is for use with only NB-IoT.
Configures the enabled 4G LTE bands for NB-IoT when the CP command is set to 1 (No Profile). If CP is
not set to 1 , the BN command value is ignored.
Changes to the value only take effect on boot so a reboot or power cycle is required for any changes
to become active.
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
