Connect Bluetooth devices

hi,
I'd like to know what happens if I have numerous Bluetooth devices in a certain area and what I'd like to happen is that anytime I'm near any Bluetooth device that is close to my pad, it will instantly connect to that device.

Is it possible? and How

You would need to pair to each device. After that (generally speaking), you will only connect to one at a time. If you come into range of a second device while still within range of the first, it will not switch over.
