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 ?
