Bluetooth v4

[Sid]

I looked at it again.

The Bluetooth LE (which is only available for versions 4 and 5) idea is perfect as is. Versions 1.1 and 1.2 drivers should be left as is.

If there is going to be any reverse compatibility drivers for traditional data rate protocols, it should be for version 4 (and when 5 becomes mainstream) dongles down to version 2.1. 2.1 has better device pairing and security than previous Bluetooth versions.
