CAN bus reverse-engineering with Arduino and iOS
Alexandre Blin

Hello. I’ve tried to reproduce your experiment, but it failed on CAN BUS communication. I’ve bought CAN BUS shield, connected it with Arduino UNO but I’m recieving nothing from cars CAN BUS. Did you plug in anything else? Like external power supply? I have just connected CANH, CANL and USB cable into the Arduino. It will connect with CAN, because initialization will pass without error, but I’m recieving no data.
