BlueZ is the official Bluetooth software stack for Linux. BlueZ is usually preinstalled in the Linux operating system across most of the variants. When using our Host Controller Interface (HCI) adapters or modules with Linux a Bluetooth driver such as BlueZ is required.
To find out the what BlueZ version your distribution of Linux is running, use the following command in the command line: bluetoothd -v
Please visit the BlueZ website for documentation and downloadable drivers: www.bluez.org/
