The nRF sniffer - Wireshark not listing the Interface

[Dil]

Hi,

I'm using Windows 10, Wireshark 3.2.17, python 3.9,   pyserial 3.5.

I see this question has been asked before but the solutions did not work for me.

I get the following output to verify the extcap.

I only have one python version (3.9) installed and pyserial is installed for that.

From wireshark I can enable, View -> Interface toolsbars-> nRF sniffer for 802.15.4. 

Still I do not get the interface listed in Wireshark to capture. Wireshark can capture packets from other interfaces.

I use the nRF52840-DK board programmed with .hex file via nRF Connect.

Next, I also tried to see with ble sniffer, but the interface does not get listed for that either.

What am I missing?

Hi

And you can confirm that the nRF Sniffer capture plugin has been installed as described here? Have you checked that the nRF Sniffer files run correctly as described in step 3 as well? 

Best regards,

Simon

Hi,

I attached the output when I asked this question. Please see the attachment in my first message in this thread.

Yes, sorry about that. After a second look at it, I see that it can't recognize a COM port either. Have you connected the correct USB port? The nRF Sniffer for 802.15.4 uses the J3 connector and USB peripheral instead of J2. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.1.0%2Fnrf802154_sniffer.html&anchor=nrf802154_sniffer_connect

Hi,

Thanks a lot! This indeed was the issue. It was confusing with the two ports and I was using the same port I used to flash since that port was detected properly by Windows.

I think it would help, if the link you have above was added to the nRF sniffer documentation section.

Thanks a lot again for your time!

Hi

Great to hear. Indeed, I reviewed the official guide myself and it is somewhat poorly communicated which USB port the sniffer uses. I have reported this internally, and we will look at making a new revision of the sniffer documentation.

Best regards,

Simon
