WebSerial Firmware Updater

in progress

Browser-based OTA firmware update tool for Nordic nRF54 devices. Uses the WebSerial API to communicate with the device over UART, sending firmware images using the MCUMGR SMP protocol to the MCUBoot bootloader — no native app or driver installation required.

WebBluetooth DFU

planned

Extension of the firmware updater using the WebBluetooth API instead of serial. Communicates with Nordic's BLE DFU service (or a custom SMP-over-BLE GATT service) to deliver firmware images wirelessly from the browser.
