Android: how to get information about connected bluetooth headset?

Question

Android

Good afternoon.
A bluetooth headset is connected to the phone. There are two questions:
1) How to get information about the headset: name, mac-address and signal status (to estimate the distance between the phone and the headset) (somehow it is possible through RSSI). I found a similar question on the overflow stack ( stackoverflow.com/questions/7169653/android-rssi-v... but there the answer concerns the devices found.
2) How to track the moment the headset is turned off (for example, the headset is in the room, and the user with the phone left to the street, that is, how to track that the signal is gone)?

Answer 1

Why didn't you turn to the official documentation ? As I understand it, to answer both the first and second questions, you need a BluetoothAdapter .
