    Monitoring CAN Data filters and mask

    Hi

    I want to monitor CANID So I using special filter and mask But then I want to get data using standard PIDS. The problem is when I send after following commands for example "0100" response is always "NO DATA" How could I fix that?

    Unfortunately, ELM327 has only one filter/mask pair. It's a limitation of its hardware. You can tweak the filter/mask bits to try to capture the traffic you want. Or can buy OBDLink, which has more flexible CAN filters.
