Anyone interested in an iDrive Arduino project I'm working on?

I was trying to retrofit idrive in other car, but i am little bit stuck.
I bought USB-CAN Analyzer from Seedstudio to send/receive can messages on desktop.
By sending 0x130 45 40 21 8F FE with 100kbps baud rate and with interval of 100ms, i can see the lights shows up on controller, but its cycling on and off.
I was trying to send 0x273 1D E1 00 F0 FF 7F DE 04 but i didnt get x277 reply from idrive.
Maybe you can help me with some hint at where i am stuck. Should be CANL pulled to gnd?

Edit: i pulled canl to ground and i can see response messages. but i am always getting 0x5E7 99E1FE0006FFFFFF 0X4E7 6702FEFFFFFFFFFF
as well as response and then shuts down, what are they? Unit is waiting for some response message?

Use 0x501 for wake up, and 0x273 for init (and should respond with 0x277)

0x5E7 is a counter, Example: 5E7 8 99 01 0A 05 01 00 00 00 | Data 0: Can ID, Data 1: Data Length, Data 5: Counter, Data 6: Rotary Init-State (6 false, 1 true)

hello IAmOrion, I am massively interested in your project. I want to be able to use the idrive touch controller with my android head unit...which is installed over a ccc unit. Where I start please?

Does your vehicle already have an iDrive controller?

I am wanting use of the touch controller to use as a mouse for the android screen. and you're from England which is great.

Yes I’m from England lol.

The problem with my implementation, is it’s specifically designed to work “standalone”. That doesn’t mean it won’t work for you, it just means I have no experience of trying it like that if that makes sense

Hi
I'm using a seed studio canbus adaptor to try and get a Idrive controller to work. Been looking at the code Iamorion used..
Can't seem to get it to work at the moment

Seed studio adaptor has a 120 ohm termination resistor - is this needed?

Yes, the 120ohm resistor is needed
