CAN transmitting
Posted: Mon Oct 26, 2020 10:27 pm
Hello,
I am investigating to replace my current SKODA Connect service with one of my own, DIY. I came across the freematics devices which are perfect for my project, however, there is something missing, CAN bus transmission.
Sorry if I do not fully understand how car buses work, my though are: Sniff the CAN bus for door lock/unlock messages and then re-transmit them to perform the action myself.
Just sniffing CAN bus is enough to know if the car is locked and will fullfil 99% of my requirements but what about retransmitting those messages? Is that even possible? How? Are these devices capable? Maybe with some work in the library?
Thanks
