Discover network topology in z-stack

Get coordinator ieeaddress and related device network address first

1.注册请求响应事件 ZDO_RegisterForZDOMsg( SampleApp_TaskID, IEEE_addr_rsp );

2.发出请求 ZDP_IEEEAddrReq(0x0000,ZDP_ADDR_REQTYPE_EXTENDED,0,0);

3.接受对应的请求响应事件

    case ZDO_CB_MSG:
             GenericApp_ProcessZDOMsgs((zdoIncomingMsg_t*)MSGpkt);
            break;

4.解析数据打印

    void Charmyin_ZDO_CB_MSGs(zdoIncomingMsg_t* inMsg)
    {
     char buf[16];
     char childAdd[4];
     uint8 shortAddress[2] = {0x00,0x00};
     char changeline[2]={0x0A,0x0D};
     switch(inMsg->clusterID)
     {
     case IEEE_addr_rsp:
       {
         ZDO_NwkIEEEAddrResp_t* pRsp=ZDO_ParseAddrRsp(inMsg);//对接受到的数据包进行解析，解析完后pRsp指向数据包的存放地址
         uint16* itemList = (uint16*)pRsp->devList;
         if(pRsp)
         {
            if(pRsp->status==ZSuccess)//解析是否正确
            {
               To_string(buf,pRsp->extAddr,8);//把MAC地址 转换为16进制形式存放
               convertFrom16To8(pRsp->nwkAddr, shortAddress);
               To_string(childAdd,shortAddress,2);//把NETWORK地址 转换为16进制形式存放
               HalUARTWrite(0,"MAC-NET:",osal_strlen("MAC-NET:"));
               HalUARTWrite(0,buf,16);
               HalUARTWrite(0,"-",1);
               HalUARTWrite(0,childAdd,4);
               HalUARTWrite(0,changeline,2);
               //遍历所有关联节点短地址，获取每个节点下的关联节点
               for(int count =0; count<pRsp->numAssocDevs; count++){
                 //To_string(childAdd, (char *)&(pRsp->devList[count]),2);
                 //HalUARTWrite(0,"Child device 1:",osal_strlen("Child device 1:"));
                 //HalUARTWrite(0,childAdd,4);

                 ZDP_IEEEAddrReq(pRsp->devList[count],ZDP_ADDR_REQTYPE_EXTENDED,0,0);
               }

             }
              osal_mem_free(pRsp);//调用该函数释放数据包缓冲区
          }
        }
         break;
      }
