Hi, 

   I encounter a issue with my printed broad that mainly copy the thingy52.  I download the thingyv210HW10.hex into my hardware. And then I debug the code (thingysdkv210) which downloaded form your network.  but it can not be debugged , it run into the bootloader DFU, at this time I can scan my device with the nRF Connect , it shows "ThingyDfu".  Does any body have the problem? please help me out. Thank u.  My device also has the LEDs, they breathe in green color.

Hi.

Did you flash the device with the pre-compiled hex file from our website?

How to you debug the code?

Did you press the button when restarting the device?

Best regards,
Joakim

Yes I flash the device from your website.

I use the keil and jlink debug the code.

No, I do not press the button. In fact my board does not have button, I test the pin that connects the button in your board , it show high level. 

thank you.

Ok, that might be the issue. When starting the device with the button pressed, it will start as ThingyDFU and be ready for a DFU.
