+    \class BtDeviceModel
+    \brief The data model provided to Bluetooth UIs in QT
+
+    BtDeviceModel provides APIs for accessing the data of remote devices. 
+    In addition, signals from this
+    model are provided for being informed of data update. 
+    
+    This model is in one dimension (n rows * 1 columns), i.e.,
+    
+          row 0 ( a remote device)
+          row 1 ( another device)
+          ...
+    
+    The data in this model is non-modifiable from the user interface (except device
+    search may add a number of in-range devices temporarily) , 
+    determined by the characteristics of Bluetooth, the underline BT software 
+    services and the BT application requirements. 
+    
+    Whenever feasible, the detailed description should contain a simple
+    example code example:
+    \code
+    // ...
+    \endcode
