Can't capture CANopen packets
Hello Community, I'd like to capture some data on a CANopen Network with a Raspberry Pi 4B. If i run Wireshark, without allowing non root users to capture pakets, my "can0" interface appears but, as expected, I'm not able to capture anything from it.
So I reconfigured the installation with "sudo dpkg-reconfigure wireshark-common" and answered the question with "yes". I also run "sudo usermod -a -G wireshark {username}". Now I still see interfaces, but fewer then before. Especially my "can0" interface doesn't appear. I spent the past 3 days to find a solution but unfortunately I still stuck to add my right interface in the list.
Linux Kernel 5.10.11-v7l
Using CAN Module: https://joy-it.net/en/products/SBC-CAN01
//EDIT: Found the solution to see amd choose my "can0". I also need to add my user to "gpio" group with "gpasswd -a {username} gpio". Now I can start the capture but can't see any traffic.
