Troubleshooting
- Windows: Install WinUSB driver via Zadig if the device doesn't appear.
- Browser: Must use Chrome or Edge on desktop over HTTPS. Safari & Firefox are not supported.
- Cable: Use a direct USB port and a data-capable (not charge-only) cable.
- Stuck in DFU? Power-cycle the module and retry from step one.
Something Go Wrong When Flashing?
You may need to reflash the bootloader (then flash your firmware again) if:
- Your boot light isn't blinking the way it should.
- You can't get it to say Daisy Bootloader when connecting.
- You flashed and the module won't turn on now.
