SavvyCAN on Linux with PeakCAN device

[pogwizd]

Hi,

I installed SavvyCAN (Qt6) on my PC (Linux base), an try to add my device in it (a PeakCAN USB adaptor).
Unfortunetely, it is not recognize by the application.

The device driver is in-build within my kernel, and well detected by the system (lsusb result)

When I open the "Connection Settings" window, I click the "Add New Device Connection".
In there, I select of course the "QT SerialBus..." type, and select "peakcan" in the dropdown list.
Unfortunetely, the port is not detected automatically, so I enter manually the path to the device. In my case, the is "/dev/PeakCAN", since I have added a dbus rule to link it to the proper USB port on connection.

Once the connection added, I can see that the status is always "Not Connected".

Does anyone has any clue to what I am missing?
Thanks

Have you followed the instructions? The PCAN Adapter ist a Linux SocketCAN device. https://www.peak-system.com/fileadmin/media/linux/index.php

Yes, I did follow it.
I've also noticed one thing this morning, that is when I try to select in the new connection window the PeakCAN device, I have the following error message:

qt.canbus.plugins.peakcan: Cannot load library: Cannot load the pcanbasic library: pcanbasic: cannot open shared object file: No such file or directory

Maybe I am missing something on my system?

Try this: #786

Tried it, and I have the following result:

1. When selecting "socketcan" in the "SerialBus Device Type" list, the "port" list is still empty.
2. When manually entering the "Port", I see the connection status being "Connected", but it changes to "Not Connected" after roughly 1.5s

The error messages are different though, and to be franc, I do not know why they are like those, since the driver is in-built within my kernel, and when I check in "/sys/class/net/can1/", I have all the device info.

qt.canbus.plugins.socketcan: Cannot load library socketcan: socketcan: cannot open a shared object file: No such file or folder
qt.canbus.plugins.socketcan: Cannot load library libsocketcan, some functionality will not be available.

Before that you have to init the interfaces. Then you will see them in the Savvycan socket can device list.
ip link set can0 up type can bitrate 250000
ip link set can1 up type can bitrate 250000

Yeah, that did the trick.
Thanks,
