Ultimately I'm looking to be able to connect to and intercept a button press on any bluetooth headset from within my app. Ideally disabling any other functioanlity.
I've tried a few devices and they connect in settings but my app does not find them using CoreBluetooth. I've worked with my own version of and the standard example code etc from Apple but none of my bluetooth devices are being discovered.
Is there certain hardware that is compatible and not compatible for me doing this from within my app, and if so where can I see what headsets will give me this connectivity?
