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,

After successfully flashing the hex file, the device will get closed and will be visible as an nRF sniffer Bluetooth inside the programmer app. I can see the same inside your first screenshot, so I guess the dongle is running with sniffer firmware. To make the dongle visible inside the wireshark, you need to follow the steps mentioned in the tutorial (in my first response). You can also refer to this page. Not sure on this, but the programmer will not be able to detect the dongle after rebooting with sniffer firmware. I think the error you are seeing from the programmer is because of this.

Kind Regards,

Abhijith
