Hi all, I am trying to use the nrf52840 dongle with wireshark, I was having permission errors trying to open the device in the program section of the nrf desktop suite running on Ubuntu 20 and followed the suggestions found at https://devzone.nordicsemi.com/f/nordic-q-a/52546/nrf-connect-linux/211625#211625 , adding the user to the dialout group did not do anything, the method using https://github.com/NordicSemiconductor/nrf-udev and https://github.com/NordicSemiconductor/nrf-udev/releases made the dongle visible and readable. In the program section of the desktop suite I selected to add the hex nrf802154_sniffer_dongle.hex and ran the 'write' option. During or after it ran the write option i recieved the following log

After this I had to press the reset button on the dongle for it to be recognized, but it did appear to show the hex in the dongles memory. However, I cannot find any protocol in wireshark despite having added the appropriate python script to the wireshark extcap directory (I have wireshark working successfully with the nrf BLE protocol using a dongle from Adafruit, so the pyserial and all that is in order) and wireshark does not see the dongle.
I'm very new to working with the wireless protocols and wireshark and the associated hardware so I'm not really sure where the real issue lies in this, if I've overlooked any imortant information please let me know.
Thanks,
David
