FAILED: Cannot connect to J-Link via USB

[EliasAd]

Hi,

I try to use the nRF52840 as a sniffer. I tried to follow (https://infocenter.nordicsemi.com/pdf/nRF_Sniffer_UG_v2.2.pdf) but I block in the 2.2.5 part.

When I run jlink.exe, I get a pop-up where it's tell me that "No emulators connected via USB" but I can see my dongle in the peripheral manager.

If someone have some issues.

Thanks you in advance.

That would be as a COM port - not as a J-Link.

The Dongle does not have a J-Link on it.

It's not an "issue" - it is expected behaviour!

The sniffer isn't intended to work on the Dongle:

So is there any tutorial hat it available and can show me how to set the nRF52840-Dongle as a sniffer ?

Again, the sniffer is not intended to work on the Dongle!
