    30     \brief The data model provided to Bluetooth UIs in QT

    31 

    32     BtSettingModel provides APIs for accessing BT local Bluetooth

    33     settings. In addition, signals from this

    34     model are provided for being informed of data update. 

    35     

    36     This model is in one dimension (n rows * 1 column), i.e.,

    37 

    38           row 0 (local device name)

    39           row 1 (power state)

    40           ...

    41     

    42     The data in this model is non-modifiable from the user interface, 

    43     determined by the characteristics of Bluetooth, the underline BT software 

    44     services and the BT application requirements.
