Hello! I had a 2004 E46 325i and was able to connect with the I-Bus (through wiretapping the OEM head unit connection). The Raspberry Pi was connected and over a serial connection I could read from and write to the bus -- roll down the windows, lock or unlock the vehicle, flash the hazard lights, control the volume, pop the trunk, etc.

I recently got a 2016 F30 328i and would like to accomplish something similar, however it appears I-Bus may no longer be used.

I understand there may be some limited functionality that can be accomplished strictly through the BMW ConnectedDrive APIs (such as lock / unlock).

Is it possible to hardwire a device into an F30 (such as a raspberry pi) and interact with devices in the vehicle such as windows, locks, volume, etc? Does a F30 have an alternative bus system that can be tapped/accessed for this purpose? Is a MOST bus system employed?

I am interested in what your are actual use cases are?

The objective is to create an Android app (with an accompanying Android Wear app for a smart watch) that accepts voice commands to perform the following tasks:

Use Cases:
- Roll down/up windows
- Lock/unlock vehicle
- Increase/decrease volume
- Go to next/previous track
- Toggle mode between radio, bluetooth, aux
- Open/close sunroof
- Flash the hazard lights
- Pop the trunk

For reference here's what I did in my E46: p1, p2, p3

For the E46 I replaced the OEM headunit with a 7" tablet, running the custom Android app. For the F30 I'd like to get the mobile app/wearable working and will likely leave the OEM display as is.

This is so cool! But would you leave the raspberry always powered, even when the car is parked? Aren't you worried about finding the car with a low battery charge?

An external power supply would solve that issue.

Could remote start be a use case?

Very interesting.

I know there's a CNX Connected Car server thread over on spool street that might be relevant. There should be a way to accomplish what you're looking with with rPi and OBD to Ethernet adapter. I'm pretty sure most of that stuff works with canbus commands.

~~~Do you have a link? I'd be interested in following it.~~~

I think Spool Street has private posts which make it hard to link to.

tcanuck42 and others: curious if you've found a way? I can help with the Android side, but lack knowledge on BMW's protocol.

Also, would it be possible to use this protocol to code the vehicle?
