Bluetooth adapters v 4

Bluetooth 4 adapters

The Bluetooth 4 family includes several revisions of the standard, so the capabilities of a specific adapter depend on the indicated subversion. Bluetooth Low Energy technology was introduced in Bluetooth 4.0, while Bluetooth 4.2 brought improvements to data transfer, security, and privacy for LE connections. Supported profiles, drivers, and the operating system are also important for practical compatibility.
