VESC 6+ CAN bus

I am trying to connect my VESC 6+ to a PiXtend (Raspberry Pi Extension - industrialish) via CAN bus, and struggle to recieve packages from the vesc.

Unfortunately I have not been able to find the technical data for CAN bus for the VESC 6+, so I am not sure wether they are supposed to be able to communicate.

Here is the technical data for PiXtend-V2-L CAN bus

Using the VESC tool I have full controll over my bldc motor with hall sensors, but I am not sure wether the signals are being broadcasted on the can bus. 

I went to connection -> can forward -> assign vesc adress manually -> forward communication over CAN bus

 This should in my understanding make the VESC 6+ send communication over the can bus, even tho it is not connected to another VESC (since the "Forward communication over CAN-bus icon is green).

No signals are sent on the bus at all.

Is there some kind of settings in VESC tool or connection errors I am having? 

Also tried scouring the internet for information, like a usermanual about CAN bus on VESC, with no luck.

Any kind of help would be dearly appreciated :)
