+ *
+ * @param[in]   p_advdata   Structure for specifying the content of the advertising data.
+ *                          Set to NULL if advertising data is not to be set.
+ * @param[in]   p_srdata    Structure for specifying the content of the scan response data.
+ *                          Set to NULL if scan response data is not to be set.
+ *
+ * @return      NRF_SUCCESS on success, NRF_ERROR_DATA_SIZE if not all the requested data could fit
+ *              into the advertising packet. The maximum size of the advertisement packet is @ref
+ *              BLE_GAP_ADV_MAX_SIZE.
+ *
+ * @warning This API may override application's request to use the long name and use a short name
+ * instead. This truncation will occur in case the long name does not fit advertisement data size.
+ * Application is permitted to specify a preferred short name length in case truncation is required.
+ * For example, if the complete device name is ABCD_HRMonitor, application can specify short name 
+ * length to 8 such that short device name appears as ABCD_HRM instead of ABCD_HRMo or ABCD_HRMoni
+ * etc if available size for short name is 9 or 12 respectively to have more apporpriate short name.
+ * However, it should be noted that this is just a preference that application can specify and
+ * if the preference too large to fit in Advertisement Data, this can be further truncated.
