CAN channel stopped unexpectedly, retrying... - sjoman - 2026-04-05
Hi,
Bookworm, rpi4, Pican-M, Signal K Server version 2.24.0, Can Bus 4.1.0
When I add the mcp2515 connection to signalK for the Pican-M from Can Bus 4.1.0, Can Bus creates a connection for the mcp251fxd as well (see attatchments).
I then get "CAN channel stopped unexpectedly, retrying..." in the signalK server log basically every minute. It restarts and it works fine for a minute again. I suspect it has to do with the double connection of 2515 and 251fxd, but I am not sure.
The config file of the rpi just states the MCP2515 and no MCP251fxd. From what I understand the Pican-M uses the 2515.
Any thought or inputs on the topic?
Best regards
Henrik
