Issues Launching Wio LTE Cat M1/NB-IoT Tracker in Bootloader Mode

[ian183]

I recently received a Wio LTE Cat M1/NB-IoT Tracker and have done a few code uploads to the board without issue.

I have since updated my code and would like to deploy it to the board, but I'm now unable to get the board into Bootloader mode using the standard procedure (Hold BOOT0, hit RST, release RST, release BOOT0). Standard RESET works to restart the board, but I just cannot get Bootloader mode going.

Is there another way to force Bootloader mode? If not, is there a way to do a full reset of the board to the factory state?

Thanks for your help!
