This is my first post here so bear with me. Here is what I'm trying to do:
I am making an audio box that receives a Bluetooth audio signal from a mobile device and can rewind or fast forward that audio track you are playing through the box. This is the same concept as having Bluetooth headphones that let you play/pause/fast-forward/rewind. I have searched high and low on the internet to learn how a Bluetooth audio remote works and I have come up with nothing. I researched AVRCP and I think that is what I need to use to accomplish this but I don't know how to implement it and take an electrical signal from a switch and turn it into an AVRCP signal to rewind the song on my phone. Let alone how an AVCRP signal works and how it can specify volume up or down or play or pause.
I hope I explained this well enough. If not I can explain more. Thanks for listening an I hope someone can help me solve this or at least tell me if it's possible or not and then point me down an alternate path.
