We have full support for CAN dumping.
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>]
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.
