Hi again @Carsten4207
I have an update. There’s a new version of reset.bin on the release page
Please download it, and flash to your device:
dfu-util -d 2b04:d006 -a 0 -s 0x8020000 -D reset.bin
When the device reboots, and flashes green, hold SETUP for 10 seconds to clear wifi credentials.
On reset, the device should enter setup mode (slow flashing blue) automatically.
I haven’t gotten to the root of the problem, but some corruption in the DCT area is preventing it from being rewritten normally. The new reset code fully erases the DCT area which should get you out of the problem.
There will be more steps needed to get on the cloud, but go ahead and fill in your wifi credentials. You should see the device flash green, then cyan…and cyan with intermediate blips of red.
