    \brief
    This class provides a wrapper for the core advertising parameters,
    including the advertising type (Connectable Undirected,
    Non Connectable Undirected, etc.), as well as the advertising and
    timeout intervals.

    See the following for more information on advertising types:

    \li \c Bluetooth Core Specification 4.0 (Vol. 6), Part B, Section 2.3.1
    \li \c Bluetooth Core Specification 4.0 (Vol. 3), Part C, Section 9.3
