Yes, that was the point. And those devices are already connected.
You will not see in HAL any BT device until is connected.

Well, for now I think that exporting the adapter and some attributes is
enough.
We will see in time what else might be needed.
So for start I think of the following keys for bluetooth namespace:

mandatory bluetooth.address		string (ex: 00:0d:33:44:33:c6) 
mandatory bluetooth.interface		string  (ex: hci0) 
mandatory bluetooth.interface_up	int
mandatory bluetooth.linux.driver	string   (ex: hci_usb) 
mandatory bluetooth.linux.sysfs_path	string (ex:/sys/class/bluetooth/hci0) 
optional bluetooth.HCI_version		int
optional bluetooth.HCI_revision		int
optional bluetooth.LMP_version		int
optional bluetooth.LMP_version		int
optional bluetooth.Manufacturer		string

What do you think of them ?

This will be something for future.


P.S.
I saw that in HAL 4.6 you have some bluetooth functions.
What are they for ?
