title: Connect to any bluetooth device which is already paired
body: <p>I was trying to create a personal app that easily toggles any bluetooth device that I am paired to. I was able to get <code>BluetoothDevice</code> set from <code>BluetoothAdapter</code>. I can't find a way to connect to the device. None of the existing solutions worked. Most of them are for creating a socket and communicating with it. I just want to connect to the device. Is it even possible? It's a bit frustrating to go to Settings -> Bluetooth -> Previous Devices -> Click on the device -> Connect or disconnect. Is there no method that gives us this functionality?</p>
