Hi Jin,

Did you choose the correct serial port for this device?

Best regards,

Charlie

Yes, and the LOG information shows that the device has been successfully connected.

Hi Jin,

I tried one nRF52840DK and one nRF52840 dongle on my hand, both of them have no issue. My computer runs Win10.

Did you erase the chip before programming it?

Have you tried with another computer and another nRF52840 device?

Best regards,

Charlie
