How to connect SignalK Server to vcan interface?
Hi. I am setting up a new pi to replace the old one on boat. For testing and configuration, I routed the physical can0 interface on the boat to vcan0 on the new pi at home using canneloni (https://github.com/mguentner/cannelloni). That works great--I can candump vcan0 successfully--but the vcan0 interface, set up as a data source, is not read by the server. Error message from the server log below. I would be grateful for any advice to resolve this issue.
