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

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!

Hi there~

Please press and hold BOOT button at back side of the Wio LTE Cat NB1 and plug the USB to PC. It shall be able to enter bootloader mode. Hope it helps. thanks.

Hello Ian, did you solve your problem? I’ve been experiencing the same problem, I can’t get the WIO in DFU mode neither
