Reading and Interpreting CAN data

However when I call the candump command nothing is displayed. The bus is properly terminated with 120ohm resistors.

I’m reading can data into a mono application, but my interface to the canbus itself is based on the candump code, which is then piped to my main program. I’m thinking that until/unless you can see the data with candump there’s not much point in fiddling with any other code. Are you able to view data in candump when sent via cansend?

Just saw your previous post. You may need to do something like:

ip link set can0 type can bitrate 20000 triple-sampling on restart-ms 100

ip link set can0 up

and set the bitrate etc appropriately before candump cooperates.
