nRF52840 dongle issue as BLE sniffer

[Launix]

Hello,

I use Programmer tool in nRF Connect for Desktop (v4.2.0) to programm sniffer_nrf52840dongle_nrf52840_4.1.1.hex firmware.

I have no problem to upgrade via bootloader using Reset button.

But i can't detect the dongle on Wireshark. It looks not working too on nRF.Connect for Desktop:

Thanks

Hello,

Have you completed the steps I pointed out in the tutorial? Your BLE device won't be visible as a sniffer unless you finish adding a wireshark profile for the nRF sniffer. See the steps mentioned here. Could you share a screenshot if you have already finished with this?

Kind Regards,

Abhijith

Hello Abhijith,

I had been already able to sniff BLE trace on Wireshark with this dongle. I managed to add a profile as described in document. 

Tonight, the dongle is detected by Wireshark:

I have no idea why i was not able to have a hardware detection on Wireshark previously. (I updated nrfConnect Desktop on 4.2.1 tonight).

I expect i will have no more kind of problem. I can catch BLE frames now.

Thanks a lot for your help.
