My current car has a small Bluetooth Adapter for playing music though my cars AUX port, but its not great. I am currently looking at the idea of building a Raspberry Pi based version of this. I found the following instructables article showing how to get the Pi to act as a Bluetooth audio device, but i have a question:
- Has anyone done anything similar and have suggestions?
- Can the Pi send "messages" back to the phone?
For the second question, if i hook up a small keyboard or mouse to the Pi, hitting a particular button would be the equivalent of sending play/pause, back, forward, etc, to the phone. the current in car system has a small remote on the steering wheel, which is based on RF, and unless it can be hacked, i don't think this can be used. I would like to be able to use some sort of remote, not necessarily the one that i currently have, to control the phone.
