I'm using socketcan on my 2017 honda civic, and I've managed to get to the point where I can see the output of candump and cansniffer.
My goal is to send a command via cansend to unlock the car. From perusing the forum, I know that honda typically uses B-CAN with 29 bit IDs. However, it's still unclear to me whether those 29 bit IDs should be readable via cansniffer. When I toggle lock/unlock, I don't see any new messages pop up in my cansniffer feed. Is this because cansniffer isn't showing extended messages? If so, is there a way to see these messages without investing in additional hardware?
I'm guessing my path of least resistance might be trying a different car. I'm hoping to demo the unlock mechanism at a hackathon in 2 days.
Any tips and guidance are welcome!! What would you do in my shoes? Find a different car to tinker with? Or how would you advise proceeding with the Honda?
Thanks so much!! I'm very excited to have made it this far, I feel like the end goal is within arm's reach!
