+    \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). To reduce the likelihood of collisions, the link layer
+                perturbs this interval by a pseudo-random delay with a range of
+                0 ms to 10 ms for each advertising event.
+
+                \par
+                Decreasing 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.
