BMW R1200GS CAN-Bus Sniffer
Create a device capable of sniffing the CAN Bus of a 2010 BMW R1200 GS motorcycle. This will be accomplished using an Arduino and CAN Bus shield and appending the sniffer to the motorcycle's CAN Bus.
This will be the main application for driving the LED auxiliary light and heated jacket implementation.
Prints out all known events to either the TFT display or the serial terminal. This is mostly used for debugging, demos, and new message discovery.
Prints all the messages raw to the terminal in a rough CSV form. This is useful for finding new messages.
Connecting to the Alarm wiring harness
The extremely overpriced BMW repair plug and wiring harness can be purchased here.
Pinout on the Alarm harness

- 5: CAN Low
- 6: CAN High
There is a group of people working on reverse engineering the CAN bus messages in a Google Spreadsheet. I've used this as the basis for my parsing, but have found some of the information to be incorrect.
One of the more "whiz-bang" features I added was a TFT display that allows me to see the status of the bike without staring at the computer screen. It most likely won't be used in the final implementation but I thought it was a cool demo.
