802.15.4 nRF Sniffer Option not Showing up in Wireshark

[jgw_sw_eng]

Hello,

I have followed these instructions, but the nRF sniffer option does not show up as an option in the Wireshark GUI, https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.0.0%2Fnrf802154_sniffer.html

I am using a Windows machine. I have tried to start up wireshark via desktop icon and command line. In both cases, I don't see any errors, but there is no nRF interface option.

I was able to successfully flash the firmware to my nRF52840 DK (PCA10056), but nothing comes in that GUI. I have made sure that I am connected to the correct USB port, and that all the switches are in the correct position, but regardless of what I do, nothing shows up. I have copied both .py and .bat files to the extcap folder.

Anything else I can try on the wireshark side to figure out the problem? Also, is there a way I can connect to the Nordic DK by RTT or serial to view logs and see if the FW is uploaded correctly?

Thanks!

Marjeris,

Thank you for the information. When I leave SW9 on VDD, the LED1 will blink even with the USB cable attached to the port on the long side of the DK (as pictured). It also blinks correctly with the cable in the port. However, in the picture, it appears SW9 is on USB - when I use that position, LED1 does not blink, event with the USB cabled plugged into the long side.

Either way, I still don't see the interface appear in Wireshark, even after copying the bat and py files. Anything else I can try?

Hi, I am sorry I haven't come back to you on this. Are you still having trouble? Perhaps you can check if the sniffer firmware is flashed correctly on the DK? Or test with another  DK or the dongle?

What does the output log looks like when you used the 'nrfjprog' command to flash the sniffer firmware to the DK?

Best regards,

Marjeris
