Determine the 64-bit address of the “Target” device (device whose firmware will be updated).To update ‘n’ remotes at once, ‘n’ different Updater devices would be required.Īt a high level, the OTA firmware update algorithm consists of 4 steps: Each Updater can only update one Target at a time.

The Source device must operate in API mode. The Updater and Source can be the same device when the source is 1-hop away from a Target.

Source: This device receives the firmware image serially and transmits it to the Updater.

The Updater can be multiple hops away from the Source. The Updater receives the firmware image, either serially or over-the-air in the mesh network, and sends the image to the Target.

Updater: This device is 1-hop away from the Target device.Target: Device in the network whose firmware image is being updated.In this document, these devices are named as follows: Over-the-air updates require 2 or 3 devices to perform the update. This feature allows a single device to update firmware on all other devices in the network. ZigBee for S2C firmware includes support to update module firmware over-the-air.
