Hi,

I installed mint in a VM, and noticed that when I ran wireshark as root, it started sniffing as expected.

Can you try to add your user to the wireshark and dialout group?

sudo usermod -a -G wireshark youruser
sudo usermod -a -G dialout youruser

Then reboot and see if it starts to sniff as expected.

This allowed my user to run wireshark properly:

Kind regards,

Håkon

Hi,

[quote user="rdmeneze"]One thing that I noticed is that on the wireshark is appearing the device as /dev/ttyACM0-3.6 [/quote]

Similar on my end:

but at my end it starts up as expected:

I also have the similar config profiles as you have:

Kind regards,

Håkon

Yes, I can see the /dev/ttyACM0 on the terminal.

One thing that I noticed is that on the wireshark is appearing the device as /dev/ttyACM0-3.6

this afternoon I'll try to update the udev rules

Hi,

I have the same version of wireshark installed, running on ubuntu, but I do not have this problem at my end.

Do you have access to the /dev/ttyACM0 device from your user?

If not, you can install the udev rules for all nrf devices and reboot (or reload udev):
