Hello,
Anyone have any examples on how to sniff CAN bus using 'OBD-II UART Adapter V2.1 (for Arduino)' and OBD2UART.h lib?

I'm trying to figure out if I can sniff out broadcast PIDs with this HW/SW. Has anyone had any success?


Thanks,

Paul

PID can be read on demand such as RPM, speed, temperature. But it is not possible to sniff the entire CAN bus freely with this hardware
