LoRaWAN FUOTA

Overview

An application to demonstrate firmware-upgrade over the air (FUOTA) over LoRaWAN.

The following services specified by the LoRa Alliance are used:

• Application Layer Clock Synchronization (TS003-2.0.0)

• Remote Multicast Setup (TS005-1.0.0)

• Fragmented Data Block Transport (TS004-1.0.0)

The FUOTA process is started by the application and afterwards runs in the background in its own work queue thread. After a firmware upgrade is successfully received, the application is notified via a callback and can reboot the device into MCUboot to apply the upgrade.

A LoRaWAN Application Server implementing the relevant services is required for this sample to work.
