Can't flash firmware on nrf52840 dongle, the error is "Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device. "

Hi,

I had used nRF Connect Programmer to flash nRF Sniffer firmware on my nRF52840 Dongle, but after that, when I tried to flash the firmware again, I found that there was always an error, "Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device" when I tried to connect with my dongle via nRF Connect Programmer. 

nRF connect is v3.6.1

programmer, v1.4.8

Jlink, v6.96

    Hi

    Can you show me the log output by nRFConnect when you try flashing the sniffer firmware onto it? A common "issue" is that nRFConnect won't recognize the Dongle after the Sniffer firmware has been flashed onto it. If you open Wireshark however, you should see that it is available as a COM port that can be used as a Sniffer as intended. 

    This is because the new firmware won't use the bootloader to get recognized by the computer, so for most firmware for the Dongle, the nRFConnect programmer log will end in "Device not found", but before that you should see something like this in the log.
