Device Firmware Upgrade Sample with Zephyr & MCUboot

Exploring zephyr's device firmware update capabilities - zephyr, mcuboot, mcumgr, stm32, esp32

A real-time PC system monitor running on a Black F407VE (STM32F407VET6) board with Zephyr RTOS

Over-the-air firmware updates over bluetooth using MUCmgr's SMP procotol

Pure-Dart client for the SMP / MCUmgr protocol (OS, Image/DFU, Filesystem) on Zephyr & MCUboot devices — all platforms, bring your own transport (BLE/serial/TCP).

Battery-powered in-hive sensor for climate, vibration and acoustic monitoring. Built on XIAO nRF54LM20A Sense with Zephyr, BLE beaconing, FFT analysis and MCUboot OTA, designed to integrate wirelessly with HiveHub.

Host CPU load on the Arduino UNO Q's LED matrix, built with stock Zephyr/west/OpenOCD instead of the Arduino App framework

Reliable LoRaWAN Class-C FUOTA on Zephyr RTOS for ESP32-S3 + SX1262, with the out-of-tree patches that make multicast firmware download work

A/B updates with automatic rollback for constrained edge fleets: silence is a rollback, and the fleet halts itself. Digest-bound manifests, SBOM diffing, reproducible-build checking, and waved rollouts whose halt has no override.

A tool in development used for doing device firmware updates (DFU) over Bluetooth LE. All in your browser.

Open-source release assurance for secure, auditable Zephyr firmware.

Secure A/B OTA bootloader for nRF52840 using MCUboot, ECDSA-P256 signing, and BLE SMP firmware delivery

Secure IoT firmware update mechanism with secure boot, cryptographic signing, firmware verification, rollback protection, TLS, RBAC, and device-side trust validation.
