How do Bluetooth Headsets work?

[rowanbradley]

I'm trying to connect my Bluetooth headset to a Windows 7 PC so that I can receive and make Skype calls. The headset seems to have successfully paired with and connected with the PC, but I can't get anything to play through it.
How do I check what is going wrong?
If I look in Devices and Printers, I can see the headset there.
If I right click on it and select Properties, and then look in the Services tab, it says that the headset is enabled for Audio Sink, Handsfree Telephony and Headset.
If I look under the Hardware tab, I see Bluetooth AV, Bluetooth hands-free and Bluetooth Headset.
If I look in the Sound control panel, under the Playback tab, the only device I see is Speakers. Should I see the headset here, if it's connected properly?
If I look in Sounds under the Recording tab I see Microphone (default device), Line in (currently unavailable) and Stereo Mix (currently unavailable). Is this correct, or should I see the headset here too?
How do I tell Skype to use the headset and not the speakers or the built in microphone? If I plug in a wired headset, it automatically switches off the built in speakers and microphone, and any phone calls that I then make will use the headset - why doesn't this happen with the Bluetooth device?

How do I debug all this stuff? How do I see how the headset is connected? How do I see what profile the sound applications (Skype, Lync, Media Player etc.) are using? How do I see what messages the answer button on the headset is sending?

I just need to understand this stuff better so I can have a chance of getting it all working...

I searched your question ( How do Bluetooth Headsets work? - YouTube ) You just need to find your bluetooth headset there

Thanks for your suggestion. Actually my "headset" is a Nokia LPS-5 which links to my hearing aids, so nothing here is precisely relevant. I imagine that the LPS-5 works exactly like a normal bluetooth headset, and in any case many of my questions are about Windows and my phone, not about the headset itself.
