 *          in the supplied structures, and passes the encoded data to the stack.
 *
 * @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.
