zigbee单播、组播、广播 单播: 按照 协议 离婚协议模板下载合伙人协议 下载渠道分销协议免费下载敬业协议下载授课协议下载 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: enum { AddrNotPresent = 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 // Fill out the endpoint description. GenericApp_epDesc.endPoint = GENERICAPP_ENDPOINT; GenericApp_epDesc.task_id = &GenericApp_TaskID; GenericApp_epDesc.simpleDesc = (SimpleDescriptionFormat_t *)&GenericApp_SimpleDesc; GenericApp_epDesc.latencyReq = noLatencyReqs; // Register the endpoint description with the AF afRegister( &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 ) { // Successfully requested to be sent. } else { // Error occurred in request to send. } 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 工程第三方检测合同工程防雷检测合同植筋拉拔检测方案传感器技术课后答案检测机构通用要求培训 AF_INCOMING_MSG_CMD事件: afIncomingMSGPacket_t结构的数据包进行处理 afIncomingMSGPacket_t结构如下: typedef struct { osal_event_hdr_t hdr; uint16 groupId; uint16 clusterId; afAddrType_t srcAddr; byte endPoint; byte wasBroadcast; byte LinkQuality; byte SecurityUse; uint32 timestamp; afMSGCommandFormat_t cmd; } afIncomingMSGPacket_t; 其中afMSGCommandFormat_t结构如下: typedef struct { byte TransSeqNumber; uint16 DataLength; // Number of bytes in TransData byte *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_t SampleApp_Group; 2.对aps_Group_t结构体赋值，示例如下: // By default, all devices start out in Group 1 SampleApp_Group.ID = 0x0003; osal_memcpy( SampleApp_Group.name, "Group 3", 7 ); 3.设定通信的目标地址，示例如下: // Setup for the flash command's destination address - Group 1 SampleApp_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: // Fill out the endpoint description. SampleApp_epDesc.endPoint = SAMPLEAPP_ENDPOINT; SampleApp_epDesc.task_id = &SampleApp_TaskID; SampleApp_epDesc.simpleDesc = (SimpleDescriptionFormat_t *)&SampleApp_SimpleDesc; SampleApp_epDesc.latencyReq = noLatencyReqs; // Register the endpoint description with the AF afRegister( &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 { // Error occurred in request to send. } 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 ) { // Remove from the group aps_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, &SampleApp_TransID, AF_DISCV_ROUTE, AF_DEFAULT_RADIUS ) == afStatus_SUCCESS ) { } else { // Error occurred in request to send. } 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 4.对数据的处理与单播的实现一样
