Load 802.15.4 firmware on ZB devices
Background
Our XBee/XBee-PRO ZB RF modules are built on the same hardware as the XBee/XBee-PRO S2C
802.15.4 RF Module. It is possible to load 802.15.4 firmware on existing ZB modules. The table below
shows which part numbers are compatible with 802.15.4 firmware.
Note
Currently the 802.15.4 firmware is approved for use only in the United States, Canada, Europe,
Australia and Japan. You can find region-specific regulatory information for the firmware in
information.
CAUTION! The antenna cable loss requirements for the 802.15.4 firmware are different than
the ZB firmware for gain antennas exceeding 2.1 dBi. If you migrate a ZB device to 802.15.4
firmware, and are using gain antennas, you must adhere to the cable loss requirements
found in

In addition to the differences between the 802.15.4 and Zigbee protocols, some of the operational
features are different between the two firmware versions. For example, the XBee-PRO 802.15.4
supports fewer channels than the Zigbee firmware. It is important that you read and understand this
user guide before developing with the 802.15.4 firmware.
Load 802.15.4 firmware
To load 802.15.4 firmware on an existing ZB module, use the following instructions. You must use the
serial interface to perform this update. The device does not support OTA updates for changing
802.15.4 to ZB firmware or vice versa.
1. Verify that your device's part number (listed on the label) is included in the list shown in
Background.
2. Install the device in a Digi development board and connect it to your PC.
3. The next steps involve loading firmware using XCTU. To download XCTU and read detailed
instructions about it, go to:
