FUOTA Using LORAWAN and Zephyr: DFU in the 'Real' World

on YouTube ↗42m

" summary

Claims a practical FUOTA path for Zephyr devices sending >500 kB artifacts by treating LoRaWAN as SMP over LoRaWAN and extending intercreate’s smpclient plus Semtech’s LBM. Implements a ChirpStack-based application server, chops images into 4KB block chunks, uses LoRaWAN FEC/multicast and Zephyr MCU manager, and runs end-to-end on an nRF5340 DK. Demonstration shows resumable uploads and mid-update transport switch; notes high FEC overhead and incompatible spec versions in current FUOTA.
