Detecting and recovering from CAN errors

[kevinlieb]

I am using the built-in CAN support on esp32-S3.

I am looking for a way to detect when CAN has "gone bad" or just stopped working. My symptom is I am getting and sending messages just fine and sporadically it stops. The rest of the program is functioning but no CAN is received. I suspect noise or something has caused a failure but i don't see a way to detect via event or something else. In this scenario power-cycle seems to bring it back but then it'll fail without notice again.

Thanks in Advance!
