Bm (Bandmask) (Lte-M); Bn (Bandmask) (Nb-Iot) - Digi XBee 3 Cellular LTE-M User Manual

AT commands

BM (Bandmask) (LTE-M)

Note This command is for use with only LTE-M.
Configures the enabled 4G LTE bands for LTE-M when
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.
