I've been thinking of a new project for a while. I want to use a bluetooth module to play audio from my phone in my car. I'm thinking of this module. I'll connect the module to one of the AUX inputs of my headunit.
The following functionality should be provided by an arduino:
- Receive CAN bus signals from the steering wheel controls and send these to the bluetooth module for next track, etc. I'm already working on the CAN bus connection of an arduino to my car (in another project)
- Read metadata (AVRCP) from the track and show it on a display. Maybe it's even possible to show it on the MFD in the car (via CAN bus)
Is this feasible with that bluetooth module? Wiring the buttons should be possible, but displaying the metadata might be hard? Would I need a serial connection to the bluetooth chip?
Does anybody have experience with that module? Or would another (low cost) module be better?
