XIAO nRF52840 & Wio-SX1262 Kit for Meshtastic & LoRa

Hello,
I’d like to assemble the kit product from the single components (XIAO nRF52840 and the XI-SX1262), since I have them already ordered and delivered… I’m looking for the Meshtastic firmware .uf2 file to program the XIAO nRF52840. I had no luck with the Meshtastic web flasher to program my device. Is there already a downloadable firmware .uf2 file available somewhere?

G’Day!
I was able to flash the Meshtastic firmware to the device via the Meshtastic Web Flasher. The trick is to use the (latest) unstable (ALPHA) firmware. The Bluetooth pairing Pin then is 123456.

You can build the firmware yourself using the Meshtastic firmware source:

  1. Clone the Meshtastic firmware repo.
  2. Follow the Meshtastic build instructions using PlatformIO.
  3. Use the adafruit-nrfutil tool to convert the resulting .hex file to .uf2.

You can convert .hex to .uf2 with this Python tool:

git clone https://github.com/microsoft/uf2
cd uf2/utils
python3 uf2conv.py path/to/your/firmware.hex -c -o firmware.uf2
