hello,
I want to write a small app wherein am able to broadcast a message to a
piconet. However to start of with, i found that bluetooth version
1.2doesn't have mutlicast support[1].

However a little of googling and i found that bluetooth version2.0 supports
multicasting :) [2]

So now here's a question [might be stupid for some but am stuck :( ]. How do
i find out whether a given bluetooth adapter adheres to version 2.0 ? .

hciconfig -a on current adapter shows the following output.

hci0: Type: USB

Is the HCI Ver. the one i should look out for ?
Any help on this would be greatly appreciated.
