I apologize in advance if this the wrong forum/Topic area. This is about a bootloader for the RAK4630 WisDuo module. I can’t seem to locate one that works with this module.
Background: I recently purchased two WisMesh Pocket radios from Rokland, they have a RAK4630 WisDuo module+ RAK19026 WisMesh BaseBoard, preprogrammed with Meshtastic firmware (2.5.20.4c97351). I used Platform IO to recompile Meshtastic, selected a target as Rak4631, flashed the firmware via the Web interface with the UF2 file, and then the device serial port would no longer appear when connected via USB.
I purchased a nanoDap and then tried uploading new bootloader, I tried the wiscore_rak4631_board_bootloader-0.4.3 file found on the RakWireless github repo. This did not restore serial port on USB connection. I tried other various bootloader files I found via web searches and no success.
I finally used the nanoDap to dump the memory of the working radio, then flashed this into the bricked radio, and it worked. I can continue doing this if I kill the serial port soft-device again, but I would like to just have a bootloader bin file that has the bootloader + serial port + UF2 interface if possible.
Or else, I would just like to understand why my previous effort using the wiscore_rak4631_board_bootloader-0.4.3 did not work. I assume this is the wrong bootloader and I need one for this particular module, but I could not find it. I am new to this and am just trying to learn.
Thanks.
