Serial firmware updates

You can update firmware on the XBee/XBee-PRO Zigbee RF Module serially.

Serial firmware updates use the XBee custom bootloader which ships in all units. This bootloader is based on Ember's standalone bootloader, but with a modified entry mechanism. The modified entry mechanism uses device pins 4, 10, and 29 (DIN, DTR, and RTS respectively) on the SMT, and pins 3, 9, 16 on the TH.

XCTU can update firmware serially on the XBee/XBee-PRO Zigbee RF Module. Contact Digi support for details.

If an application requires custom firmware to update the XBee firmware serially, proceed to Invoke the XBee bootloader.
