there. Since I recently just started on my first projekt with the Rpi, Iam a noob when it comes to figuring solutions out..
I successfully connected my iPhone with the Raspy (Model 3, B+) and it is possible to "stream" music and other audio sources from the phone to the Raspy and than to the 3,5mm jack.
I followed this tutorial: Bluetooth audio streaming.
But now I have got the problem that I can not change the volume via my phones buttons (neither physical nor "software-based").
Can somebody help me to figure out how to change the volume via bluetooth connection from my phone?
Would be great to see a tutorial that shows all the single steps I have to do.
