Sniffer is not listed in the Wireshark interface

Check the following:

1. Ensure that the Development Kit (DK) or dongle has been enumerated on Universal Serial Bus (USB) and that the drivers are loaded.
2. Ensure that the firmware HEX file has been programmed.
3. Reset the hardware by unplugging it, waiting 5 seconds, and plugging it back in.
4. Check the sniffer log file log.txt for error messages. You can find the file in the /logs directory at the nRF Util's installation location.

If these steps do not resolve the issue, verify that you have installed the nRF Sniffer capture tool correctly.
