How to find out if I'm using Bluetooth 3.0 + HS
I recently bought a Hama bluetooth 3.0+HS dongle. I'm using it with my Ubuntu 10.04. Ubuntu recognizes the dongle and I am able to set up BT devices. But how can I check whether it is actually using version 3.0 rather than 2.1?
Run the hciconfig -a
command, it'll list all Bluetooth devices and the supported versions
