定向广播求助？

1、有些资料说定向可连接广播类型分成两种方式（High duty cycle和Low duty cycle）。且在（include/gap.h），具体定义的类型如下：

 GAP_ADTYPE_ADV_IND //!< Connectable undirected advertisement

 GAP_ADTYPE_ADV_HDC_DIRECT_IND //!< Connectable high duty cycle directed advertisement

 GAP_ADTYPE_ADV_SCAN_IND //!< Scannable undirected advertisement

 GAP_ADTYPE_ADV_NONCONN_IND //!< Non-Connectable undirected advertisement

 GAP_ADTYPE_ADV_LDC_DIRECT_IND //!< Connectable low duty cycle directed advertisement

但是，怎么找不到GAP_ADTYPE_ADV_HDC_DIRECT_IND 和GAP_ADTYPE_ADV_LDC_DIRECT_IND ；只有

#define GAP_ADTYPE_ADV_IND                0x00  //!< Connectable undirected advertisement

#define GAP_ADTYPE_ADV_DIRECT_IND         0x01  //!< Connectable directed advertisement

#define GAP_ADTYPE_ADV_DISCOVER_IND       0x02  //!< Discoverable undirected advertisement

#define GAP_ADTYPE_ADV_NONCONN_IND        0x03  //!< Non-Connectable undirected advertisement

#define GAP_ADTYPE_SCAN_RSP_IND           0x04  //!< Only used in gapDeviceInfoEvent_t

这是什么问题？

2、Direct Advertisement Address Type和Direct Advertisement Address.又要怎么配置？有什么作用？

     主机代码：
    static uint8 bdAddress[6] = {0xff,0xff,0xff,0xff,0xff,0x03};
        HCI_EXT_SetBDADDRCmd(bdAddress);
    然后将拨码开关的组号与bdAddress[0]相或

              if ( simpleBLEState == BLE_STATE_IDLE )

                  LCD_WRITE_STRING( "simpleBLEScanIdx = 0;", HAL_LCD_LINE_1 );
                }
                uint8 addrType;
                uint8 *peerAddr;
                // connect to current device in scan result
                peerAddr = simpleBLEDevList[simpleBLEScanIdx].addr;
                addrType = simpleBLEDevList[simpleBLEScanIdx].addrType;
                simpleBLEState = BLE_STATE_CONNECTING;

            }
            // initialize scan index to last device
            simpleBLEScanIdx = simpleBLEScanRes;
