HI Nagesh,

Reporting "Nordic DFU Trigger Interface was not found. Please physically reset device." is not a problem. This just means that the device is no longer in DFU mode, and hence, it is not responding to the USB as a DFU device, which is what nRF Connect is looking for. As long as you see "DFU for application completed successfully!" from the log, your application program should be programmed through DFU.

Best regards,

Charlie

Yes, i did. I tried multiple times by making sure the dongle enters DFU mode with red led blinking. but still i am facing same issue.

i even had an alternative dongle and facing the same problem with another dongle as well.

Hi Nagesh,

Did you push the reset button to let nRF52840 Dongle enter DFU mode?
You can find how to program nRF52840 Dongle from Nordic Semiconductor Infocenter.

Best regards,
