Digi XBee 3 ZigBee User Manual

Over-the-air firmware/file system upgrade process
for Zigbee 3.0
The FOTA upgrade process is based on the Zigbee Cluster Library specifications; ZCL messages are
exchanged between the server and the client using 0x11 explicit addressing API frames with a cluster
ID of 0x0019. All multiple byte values in the ZCL command in the payload must be sent in little endian
byte order for the command to be executed correctly on the remote device.
For the server to receive the required ZDO responses from the client, set AO (API Options) to 1 to
enable the Explicit Rx Indicator frame - 0x91. The client automatically generates the necessary
responses regardless of its serial configuration.
