Monitor the unfiltered logs (required USB debug mode) and see which intent is sent when you press on the buttons.

Search community for "headset" and you will find some solutions. For me, for example, work very well.

I have do but i find no useful info! Anyone else?

 

[appie21]

Hoe van i work with The state of The pressed button. Anyone?

 

[appie21]

I have try hard to get this fixed.

How can I work with the data of the log file?

I not need to connect the bluetooth device with a function it is already connected to the device!

 

[Erel]

No intent is sent based on these logs.

What does the state mean? (state12newState0) it happend when i press button

 

[Troberg]

I have a similar problem. Got a bunch of bluetooth earpieces, which I want to use as push-to-talk walkie talkies. Basically, push the button in your ear, and everything you say will be sent by your phone to the other users.

I get no keypress, but the music player on the phon toggles play/pause. Is there a way to get that click?

If anyone is interested, it's this one (very nice, recommended): http://www.aliexpress.com/item/Smal...th-Mini-Earphone-Headset-YKS/32318905350.html

The unfiltered logs show all the output of all programs. It is hard to say what is the meaning of this message.

It will not work. You cannot connect to a headset with SPP (serial profile). The connection is handled by the OS.
