nRF Sniffer : no packets captured

[QuentinFarizon]

I'm using the nRF 52840 Dongle, flashed with nRF Sniffer 3.1.0.
I have installed Wireshark version 3.0.7, and configured extcap and profile according to documentation. 
I am on Ubuntu 20.04.

"nRF Sniffer for Bluetooth LE: /dev/ttyACM0" is displayed on the Wireshark interface, and I have the NRF Sniffer toolbar (with only the "All advertising devices" option)

When capturing, I get no packets (though I have dozens of advertising BLE devices around).

What am I missing ?

Hi QuentinFarizon,

Have you checked the solution mentioned on this ticket?

Best regards,

I'm not sure to understand the phrase "after wireshark indentifies the inferface, I disconnect the Dongle and start capturing."

I have tried to plug it off and on again before capturing, and also after capturing, but it didn't work (it's not blinking when plugged back)

Hi Quentin,

I set up a similar environment to try, everything seems working fine. 

Do you have another nRF52840 Dongle or DK to try? Or just reprogram the one in your hand and try it on Windows version Wireshark just in case it is a Ubuntu permission issue?

Best regards,
Charlie
