-
-    The Bluetooth Tennis example shows how to use the Qt Connectivity Bluetooth API
-    to implement real-time data transfer for interactive applications. The example
-    establishes a \l {QBluetoothServiceInfo::L2capProtocol}{L2CP} socket connection.
-    Since this protocol type is not supported on Android and BlackBerry the example
-    does not work on those platforms.
