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
