I am using 12.04 on my machine. I want to check which version of Bluez right now my machine using. How to check that.


BlueZ has a daemon process named 'bluetoothd'
Issue command: bluetoothd -v to get the active or working version of BlueZ.


Open a terminal and enter

dpkg --status bluez | grep '^Version:'

or the slightly more obscure

dpkg-query -Wf '${Version}\n' bluez

You could go to the Software Center, search for “BlueZ” and click on the first entry. The version number is given below the description.

As for reference, on Ubuntu 13.04, I have bluez 4.101-0ubuntu8b1.
