Wireshark not recognising nRF52840 Dongle as an interface.

[hevii]

My nrf52840 dongle isn't being recognised as an interface on Wireshark 4.0.4 running on Mac OS 11.7.2

• The "nRF Sniffer for Bluetooth LE" toolbar is loaded and visible in Wireshark but is empty.
• I can run the ./nrf_sniffer_ble.sh --extcap-interfaces command from within the Wireshark extcap folder.

Based on the number of other similar posts, this seems to be a common probem. Assistance will be appreciated.

HI Bubba, 
Could you let me know what's the log when you call  ./nrf_sniffer_ble.sh --extcap-interfaces ? 
I assume you have flashed sniffer firmware on the nRF52840 dongle. Do you see a new COMPORT opened on the computer ?
Which Python version do you have ? Do you have multiple python instances ?

The dongle is fuctional. It works as intended in "nRF Connect for Desktop Bluetooth Low Energy".

The dongle is recognised by the Mac:

Hi Bubba, 
Have you performed this step: 

https://infocenter.nordicsemi.com/topic/ug_sniffer_ble/UG/sniffer_ble/programming_firmware.html?cp=11_5_2_0

The connectivity firmware won't work as the sniffer. You need to flash the sniffer firmware as instructed in the page.

Upon first start-up of  "nRF Connect for Desktop Bluetooth Low Energy", the dongle flashed itself. Subsequent output in this program showed (copied above in my earlier post) shows that it works. Am I missing something?

[Hung Bui]

Hi Bubba, 

They are not related. The nRF Connect for Desktop Bluetooth Low Energy is a different application, it's not the sniffer.

If you want to use the dongle as the sniffer, please flash the hex file for the sniffer.

I clearly missed something. Thank-you for pointing this out and correcting my mistake, Hung.

After flashing as instructed, it all works now. This case can be closed.
