CAN sniffer stopping

Post by Gauner »

I use the can sniffer example firmware_v5/can_sniffer/can_sniffer.ino
with PROTO_CAN_29B_500K and

Code: Select all

obd.setHeaderFilter(0x00000000);
obd.setHeaderMask(0x00000000);
I want to see all messages. I receive quickly the first around 20 messages, then the program seems to stop.
If I tighten the filter on the messages, it shows the filtered messages and runs forever, as expected.
But I want to view ALL messages (to later make a negative filter, i.e. exclude messages by header... ist this already implemented?)

How can this problem be tracked down?
