hey @rhys_m, have a question. Any tips on how I can probe for canbus messages on button presses if cansniffer isn't picking them up? I have a mazda, and I'm on the ms_can network. When I run cansniffer, I can certainly see information coming through, but when I do button presses, cansniffer isn't picking them up at all.
What I'm wondering is that maybe in some systems, you need to send some sort of request message before buttons are then read? I know for a fact my buttons can be mapped via canbus, because I previously had an android head unit that had a canbus "black box" that tapped into the ms_can network and could pick up all of my steering wheel controls as key presses over can, as well as reverse signal, etc.
Just wondering what I can try if cansniffer isn't getting the job done.
Thanks again!
