Short version:
Peuget partner: RX OK
BMW X3: NO RX LED
Hello! I am using a arduino Seeduino CAN bus shield V1.2. + OBDII-DB9 cable + BMW x3 2005 e83
I am getting data from my peugeot, but not from my bmw. I've tried both the 8Mhz and 16Mhz libraries, and measured the voltage in the bmw and peugeot, which seems normal, around 2.5V, and I'm pretty sure the bmw can bus should be working. (Going to test this more thoroughly)
Given that the RX led on the shield is lighting up when it receives data without any programming on the arduino board, leads me to believe the problem is not in my code or wiring. (Given that i have 2,5V on the can bus terminals on the shield)
So i am left wondering if there could be some incompatibility between the MCP2515 and the can bus in the bmw? Anyone experienced not getting any RX light?
