I have just setup a Rak4630 with a mini base board, I a have installed platform.io and have meshtastic compiling for the board, I can’t program the device.
I get this error:
Starting DFU upgrade of type 3, SoftDevice size: 151016, bootloader size: 39000, application size: 0
Sending DFU start packet
Timed out waiting for acknowledgement from device.
I tried updating the bootloader using the adafruit-nrfutil.exe tool I also get the same error.
Looks like the new RUI firmware has a different bootloader, How do get the old bootloader on so I can flash custom firmware for platform.io?
