nRF Sniffer for 802.15.4 doesn't appear on Wireshark interface

I am struggling to see nRF Sniffer for 802.15.4 as an interface in the Wireshark interface list under the startup welcome screen. I am using nRF62840-Dongle and flashed it by utilizing the nrf802154_sniffer_dongle.hex available under the GitHub nRF-Sniffer-for-802.15.4 repository. I didn't find a specific binary for nRF62840-Dongle device there.

  • Since I flashed the nRF62840-Dongle device using a mismatched binary nrf802154_sniffer_dongle.hex, is it the main cause of the issue? If so, where do I get the correct binary for the nRF62840-Dongle device?

I have Python 3 installation with Homebrew including Pip 3. I have listed the relevant installation path in the following:

  • which pythonpython not found
  • which pip/usr/local/bin/pip
  • which python3/usr/local/bin/python3
  • which pip3: /usr/local/bin/pip3

I installed pyserial using pip3 install pyserial. I copied the file under the ~/.config/wireshark/extcap location which is a Personal Extcap path.

When running the python3 --extcap-interfaces command, it outputs the following valid confirmation:

extcap {version=0.7.2}{help=}{display=nRF Sniffer for 802.15.4}
interface {value=/dev/cu.usbmodemF1BD057D01BB1}{display=nRF Sniffer for 802.15.4}
control {number=6}{type=button}{role=logger}{display=Log}{tooltip=Show capture log}

So, what am I missing? Why nRF Sniffer for 802.15.4 interface isn't appearing on the Wireshark Custom Interface list?
