Bluetooth Low Energy Questions

Hi all,

I would like to know if someone could say me what's the current state of the Bluetooth Low Energy standard within the BlueZ stack, like implementations in progress, etc. Any information is welcome.

On the other hand, I have been consulting the following Bluetooth Low Energy Dongle [1]. Does anyone have used this dongle? Is it a good option to start working?

Regards.

Jorge.
