We have full support for CAN dumping.

Two options:

  1. To an SD card

    can log crtd /sd/file.crtd
    can log off

    Usage: can log crtd <path> [filter1] [filter2] [filter3]
    Filter: <bus> / <id>[-<id>] / <bus>:<id>[-<id>]
    Example: 2:2a0-37f

  2. Over WiFi

    re start
    re move serve
    re serve format crtd|pcap

    Then, on workstation:

      nc vehicleid.local 3000 | tee file.crtd

I personally use the wifi mode. You can output to crtd format (an ascii readable format), or pcap (for loading into wireshark). With wifi, you can also ‘re serve mode simulate’ and then replay CAN bus dumps back in (nc vehicleid.local 3000 <file.crtd).

If you want to test transmission, you can either do it over wifi (re serve mode transmit), or use the ‘can canX tx …’ command to directly transmit a frame.

Regards, Mark.

I'm starting to look at adding support for my Cadillac but it's not clear to me that I can use a ovms module to capture can frames? Do I need another device to do it?
