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

    Please try closing Wireshark, then do an full erase of the nRF52840 DK before flashing the sniffer firmware onto the nRF52840 DK. After flashing the device with sniffer firmware, try opening Wireshark, and the interface should appear with the correct COM port.

    If this does not make the DK show up as a sniffer interface, please make sure you've gone through the "Installing nRF Sniffer for 802.15.4" and Configuring Wireshark for Thread (or for Zigbee, depending on what you want to do sniffing actions of.

    Best regards,

    Simon

    Hi Simon,

    I have done the configuration for Zigbee and adding keys. I had followed the instructions before. 

    This time I did the 'Erase all' -> 'Erase & Write' and then opened wireshark but still the interface is not listed. I refreshed the interfaces as well but still it did not get listed.

    Is there any way I can debug what is wrong?

    Can you show me a screenshot of how your Wireshark "main window" looks like? The interface I showed you in my previous reply only seems to be for the nRF Sniffer for BLE, as the Zigbee and Thread sniffer is a bit more "basic".

    Best regards,

    Simon

    Hi,

    I have attached a screenshot of the wireshark window, after doing the following.

    1. Capture -> Refresh Interfaces

    2. Enabling View -> Interface Toolbars -> nRF sniffer for 802.15.4

    At this point a full erase and write was done to the DK board. Other configurations such as keys in wireshark is also done. As in the image, the interface is not listed.

    Thanks in advance!
