zigbee单播、组播、广播zigbee单播、组播、广播单播：按照协议栈示例GenericApp中的用法：单播有两种方式一种是绑定传输，一种是直接指定目标地址的单播传输按照如下步骤1.设定发送的目标地址GenericApp_DstAddr.addrMode=(afAddrMode_t)AddrNotPresent;GenericApp_DstAddr.endPoint=0;GenericApp_DstAddr.addr.shortAddr=0;设定发送的目标地址，这里地址模式AddrNotPresent，即按照绑定的方式进行单播，不需要指定目标地址，需要先将两个设备绑定，将两个设备绑定后即可通信还有另外三种传送方式，如下：enumAddrNotPresent=0,/按照绑定表进行绑定传输AddrGroup=1,/组播传输Addr16Bit=2,/指定目标网络地址进行单播传输Addr64Bit=3,/指定IEEE地址进行单播传输AddrBroadcast=15/广播传输;2.注册端点描述符/Fillouttheendpointdescription.GenericApp_epDesc.endPoint=GENERICAPP_ENDPOINT;GenericApp_epDesc.task_id=&GenericApp_TaskID;GenericApp_epDesc.simpleDesc=(SimpleDescriptionFormat_t*)&GenericApp_SimpleDesc;GenericApp_epDesc.latencyReq=noLatencyReqs;/RegistertheendpointdescriptionwiththeAFafRegister(&GenericApp_epDesc);3.在需要发送数据的地方，执行如下代码：if(AF_DataRequest(&GenericApp_DstAddr,&GenericApp_epDesc,GENERICAPP_CLUSTERID,(byte)osal_strlen(theMessageData)+1,(byte*)&theMessageData,&GenericApp_TransID,AF_DISCV_ROUTE,AF_DEFAULT_RADIUS)=afStatus_SUCCESS)/Successfullyrequestedtobesent.else/Erroroccurredinrequesttosend.注意GENERICAPP_CLUSTERID必须为对方的输入cluster，且两方的简单描述符中的profileID必须一致4.在接收设备任务循环中检测AF_INCOMING_MSG_CMD事件：afIncomingMSGPacket_t结构的数据包进行处理afIncomingMSGPacket_t结构如下：typedefstructosal_event_hdr_thdr;uint16groupId;uint16clusterId;afAddrType_tsrcAddr;byteendPoint;bytewasBroadcast;byteLinkQuality;byteSecurityUse;uint32timestamp;afMSGCommandFormat_tcmd;afIncomingMSGPacket_t;其中afMSGCommandFormat_t结构如下：typedefstructbyteTransSeqNumber;uint16DataLength;/NumberofbytesinTransDatabyte*Data;afMSGCommandFormat_t;提取出Data即可-组播：按照SampleApp实验，组播的实现需要如下步骤：1.声明一个组对象aps_Group_tSampleApp_Group;2.对aps_Group_t结构体赋值，示例如下：/Bydefault,alldevicesstartoutinGroup1SampleApp_Group.ID=0x0003;osal_memcpy(SampleApp_G,Group3,7);3.设定通信的目标地址，示例如下：/Setupfortheflashcommandsdestinationaddress-Group1SampleApp_Flash_DstAddr.addrMode=(afAddrMode_t)afAddrGroup;SampleApp_Flash_DstAddr.endPoint=SAMPLEAPP_ENDPOINT;SampleApp_Flash_DstAddr.addr.shortAddr=SAMPLEAPP_FLASH_GROUP;4.注册端点描述符，示例如下：/Fillouttheendpointdescription.SampleApp_epDesc.endPoint=SAMPLEAPP_ENDPOINT;SampleApp_epDesc.task_id=&SampleApp_TaskID;SampleApp_epDesc.simpleDesc=(SimpleDescriptionFormat_t*)&SampleApp_SimpleDesc;SampleApp_epDesc.latencyReq=noLatencyReqs;/RegistertheendpointdescriptionwiththeAFafRegister(&SampleApp_epDesc);5.在本任务里将端点加入到组中，示例如下：aps_AddGroup(SAMPLEAPP_ENDPOINT,&SampleApp_Group);6.按照组播地址向对方发送数据，示例如下：if(AF_DataRequest(&SampleApp_Periodic_DstAddr,&SampleApp_epDesc,SAMPLEAPP_PERIODIC_CLUSTERID,1,(uint8*)&SampleAppPeriodicCounter,&SampleApp_TransID,AF_DISCV_ROUTE,AF_DEFAULT_RADIUS)=afStatus_SUCCESS)else/Erroroccurredinrequesttosend.通信时候，发送设备的输出cluster设定为接收设备的输入cluster，另外profileID设定相同，即可通信7.对数据的处理与单播的实现一样8.若要把一个设备加入到组中的端点从组中移除，调用aps_RemoveGroup即可，示例如下：aps_Group_t*grp;grp=aps_FindGroup(SAMPLEAPP_ENDPOINT,SAMPLEAPP_FLASH_GROUP);if(grp)/Removefromthegroupaps_RemoveGroup(SAMPLEAPP_ENDPOINT,SAMPLEAPP_FLASH_GROUP);广播:按照SampleApp，执行如下步骤即可1.声明afAddrType_t的变量SampleApp_Periodic_DstAddr;2.设定目标地址变量为广播地址，示例如下：SampleApp_Periodic_DstAddr.addrMode=(afAddrMode_t)AddrBroadcast;SampleApp_Periodic_DstAddr.endPoint=SAMPLEAPP_ENDPOINT;SampleApp_Periodic_DstAddr.addr.shortAddr=0xFFFF;3.进行数据发送，示例如下：if(AF_DataRequest(&SampleApp_Periodic_DstAddr,&SampleApp_epDesc,SAMPLEAPP_PERIODIC_CLUSTERID,1,(uint8*)&SampleAppPeriodicCounter,&S
