zigbee 广播 组播 单播

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
