    \brief
    Instantiates a new GapAdvertisingParams instance

    \param[in]  advType
                The GAP advertising mode to use for this device. Valid
                values are defined in AdvertisingType:

                \par ADV_NON_CONNECTABLE_UNDIRECTED
                All connections to the peripheral device will be refused.
                
                \par ADV_CONNECTABLE_DIRECTED
                Only connections from a pre-defined central device will be
                accepted.
                
                \par ADV_CONNECTABLE_UNDIRECTED
                Any central device can connect to this peripheral.

                \par ADV_SCANNABLE_UNDIRECTED
                Any central device can connect to this peripheral, and
                the secondary Scan Response payload will be included or
                available to central devices.
                
                \par
                See Bluetooth Core Specification 4.0 (Vol. 3), Part C,
                Section 9.3 and Core Specification 4.0 (Vol. 6), Part B,
                Section 2.3.1 for further information on GAP connection
                modes

    \param[in]  interval
                Advertising interval between 0x0020 and 0x4000 in 0.625ms
                units (20ms to 10.24s).  If using non-connectable mode
                (ADV_NON_CONNECTABLE_UNDIRECTED) this min value is
                0x00A0 (100ms).

                \par
                Increasing this value will allow central devices to detect
                your peripheral faster at the expense of more power being
                used by the radio due to the higher data transmit rate.
                
                \par
                This field must be set to 0 if connectionMode is equal
                to ADV_CONNECTABLE_DIRECTED
                
                \par
                See Bluetooth Core Specification, Vol 3., Part C,
                Appendix A for suggested advertising intervals.
                
    \param[in]  timeout
                Advertising timeout between 0x1 and 0x3FFF (1 and 16383)
                in seconds.  Enter 0 to disable the advertising timeout.
