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

case GAP_DEVICE_INFO_EVENT:
{
// if filtering device discovery results based on service UUID
/*
if ( DEFAULT_DEV_DISC_BY_SVC_UUID == TRUE )
{
if ( simpleBLEFindSvcUuid( SIMPLEPROFILE_SERV_UUID,
pEvent->deviceInfo.pEvtData,
pEvent->deviceInfo.dataLen ) )
{
simpleBLEAddDeviceInfo( pEvent->deviceInfo.addr, pEvent->deviceInfo.addrType );
}

simpleBLEAddDeviceInfo( pEvent->deviceInfo.addr, pEvent->deviceInfo.addrType );
}
break;

{
// discovery complete
simpleBLEScanning = FALSE;

simpleBLEScanRes = pEvent->discCmpl.numDevs;
osal_memcpy( simpleBLEDevList, pEvent->discCmpl.pDevList,
(sizeof( gapDevRec_t ) * pEvent->discCmpl.numDevs) );
}
*/
simpleBLEScanRes = pEvent->discCmpl.numDevs;
osal_memcpy( simpleBLEDevList, pEvent->discCmpl.pDevList,
(sizeof( gapDevRec_t ) * pEvent->discCmpl.numDevs) );
LCD_WRITE_STRING_VALUE( "Devices Found", simpleBLEScanRes,
10, HAL_LCD_LINE_1 );
if ( simpleBLEScanRes > 0 )
{
LCD_WRITE_STRING( "<- To Select", HAL_LCD_LINE_2 );
//连接第一个
HalLedSet(HAL_LED_3, HAL_LED_MODE_ON ); //开LED3
if ( simpleBLEState == BLE_STATE_IDLE )
{
simpleBLEScanIdx++;
LCD_WRITE_STRING( "simpleBLEScanIdx++", HAL_LCD_LINE_1 );
if ( simpleBLEScanIdx >= simpleBLEScanRes )
{
simpleBLEScanIdx = 0;
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;
GAPCentralRole_EstablishLink( DEFAULT_LINK_HIGH_DUTY_CYCLE,
DEFAULT_LINK_WHITE_LIST,
addrType, peerAddr );
}
}
// initialize scan index to last device
simpleBLEScanIdx = simpleBLEScanRes;
}
break;
从机：
申明 static uint8 centralAddr[]={0x00,0xFF,0xFF,0xFF,0xFF,0xF1};
void SimpleBLEPeripheral_Init( uint8 task_id )
{
.......................
uint8 gaprole_adv_event_type = GAP_ADTYPE_ADV_LDC_DIRECT_IND;
GAPRole_SetParameter(GAPROLE_ADV_EVENT_TYPE, sizeof( uint8 ), &gaprole_adv_event_type);
GAPRole_SetParameter(GAPROLE_ADV_DIRECT_ADDR,sizeof(centralAddr), centralAddr);
.......................
