【Z-Stack建立绑定关系之二-终端绑定请求方式】一2011-04-02 11:33ZDO终端设备绑定请求:设备能告诉协调器他们想建立绑定表格报告。该协调器将使协调并在这两个设备上创建绑定表格条目。在这里是以SerialApp例子为例。void SerialApp_HandleKeys( uint8 shift, uint8 keys ) zAddrType_t dstAddr; if ( shift ) if ( keys & HAL_KEY_SW_1 ) if ( keys & HAL_KEY_SW_2 ) if ( keys & HAL_KEY_SW_3 ) if ( keys & HAL_KEY_SW_4 ) else if ( keys & HAL_KEY_SW_1 ) if ( keys & HAL_KEY_SW_2 ) HalLedSet ( HAL_LED_4, HAL_LED_MODE_OFF );/终端设备绑定请求 / Initiate an End Device Bind Request for the mandatory endpoint dstAddr.addrMode = Addr16Bit; dstAddr.addr.shortAddr = 0x0000;/ Coordinator ZDP_EndDeviceBindReq( &dstAddr, NLME_GetShortAddr(), SerialApp_epDesc.endPoint, SERIALAPP_PROFID, SERIALAPP_MAX_CLUSTERS, (cId_t *)SerialApp_ClusterList, SERIALAPP_MAX_CLUSTERS, (cId_t *)SerialApp_ClusterList, FALSE ); if ( keys & HAL_KEY_SW_3 ) if ( keys & HAL_KEY_SW_4 ) HalLedSet ( HAL_LED_4, HAL_LED_MODE_OFF );/描述符匹配请求 这也是两不同匹配方式，使用的按键不同 / Initiate a Match Description Request (Service Discovery) dstAddr.addrMode = AddrBroadcast;/广播地址 dstAddr.addr.shortAddr = NWK_BROADCAST_SHORTADDR; ZDP_MatchDescReq( &dstAddr, NWK_BROADCAST_SHORTADDR, SERIALAPP_PROFID, SERIALAPP_MAX_CLUSTERS, (cId_t *)SerialApp_ClusterList, SERIALAPP_MAX_CLUSTERS, (cId_t *)SerialApp_ClusterList, FALSE ); 说明：从上面可以看到，SW2是发送终端设备绑定请求方式，SW4是发送描述符匹配请求方式。如果按下SW1的话，使用终端设备绑定请求方式，这里是要通过终端告诉协调器他们想要建立绑定表格，协调器将协调这两个请求的设备，在两个设备上建立绑定表格条目。(1)终端设备向协调器发送终端设备绑定请求 调用ZDP_EndDeviceBindReq()函数发送绑定请求。 ZDP_EndDeviceBindReq( &dstAddr,/目的地址设为0x0000； NLME_GetShortAddr(), SerialApp_epDesc.endPoint,/EP号 SERIALAPP_PROFID,/Profile ID SERIALAPP_MAX_CLUSTERS, /输入簇的数目 (cId_t *)SerialApp_ClusterList,/输入簇列表 SERIALAPP_MAX_CLUSTERS,/输出簇数目 (cId_t *)SerialApp_ClusterList,/输出簇列表 FALSE ); 该函数实际调用无线发送函数将绑定请求发送给协调器节点：默认clusterID为End_Device_Bind_req，最后通过AF_DataRequest()发送出去.fillAndSend( &ZDP_TransID, dstAddr, End_Device_Bind_req, len );最后通过AF_DataRequest()发送出去.AF_DataRequest( &afAddr, &ZDApp_epDesc, clusterID, (uint16)(len+1), (uint8*)(ZDP_TmpBuf-1), transSeq, ZDP_TxOptions, AF_DEFAULT_RADIUS );(2) 协调器收到终端设备绑定请求End_Device_Bind_req这个信息会传送到ZDO层，在ZDO层的事件处理函数中，调用ZDApp_ProcessOSALMsg( (osal_event_hdr_t *)msg_ptr );UINT16 ZDApp_event_loop( byte task_id, UINT16 events ) uint8 *msg_ptr; if ( events & SYS_EVENT_MSG ) while ( (msg_ptr = osal_msg_receive( ZDAppTaskID ) ) ZDApp_ProcessOSALMsg( (osal_event_hdr_t *)msg_ptr ); / Release the memory osal_msg_deallocate( msg_ptr ); / Return unprocessed eventsreturn (events SYS_EVENT_MSG); void ZDApp_ProcessOSALMsg( osal_event_hdr_t *msgPtr ) / Data Confirmation message fields byte sentEP; / This should always be 0 byte sentStatus; afDataConfirm_t *afDataConfirm; switch ( msgPtr-event ) / Incoming ZDO Messagecase AF_INCOMING_MSG_CMD: ZDP_IncomingData( (afIncomingMSGPacket_t *)msgPtr ); break; 在ZDP_IncomingData( (afIncomingMSGPacket_t *)msgPtr );函数中void ZDP_IncomingData( afIncomingMSGPacket_t *pData ) uint8 x = 0; uint8 handled; zdoIncomingMsg_t inMsg; inMsg.srcAddr.addrMode = Addr16Bit; inMsg.srcAddr.addr.shortAddr = pData-srcAddr.addr.shortAddr; inMsg.wasBroadcast = pData-wasBroadcast; inMsg.clusterID = pData-clusterId; inMsg.SecurityUse = pData-SecurityUse; inMsg.asduLen = pData-cmd.DataLength-1; inMsg.asdu = pData-cmd.Data+1; inMsg.TransSeq = pData-cmd.Data0; handled = ZDO_SendMsgCBs( &inMsg );#if defined( MT_ZDO_FUNC ) MT_ZdoRsp( &inMsg );#endif while ( zdpMsgProcsx.cl
