zigbee cc530关于链路质量的问题

Other Parts Discussed in Thread: CC2530

在zigbee网络中，基于cc2530，mesh组网，能否可以使终端节点和路由节点的lcd屏上显示出本节点和所连接的父节点之间的rssi值？

该怎样做？

    RSSI的值只能通过和对方进行直接通信时获取，但终端节点只能和其父节点（协调器或路由器）进行直接通信，
    其他设备只能获取终端节点父节点的RSSI值

    afIncomingMSGPacket_t这个结构体里面有rssi

    static void zclSampleSw_processAfIncomingMsgInd(zstack_afIncomingMsgInd_t *pInMsg)
    {
    afIncomingMSGPacket_t afMsg;

    /*
    * All incoming messages are passed to the ZCL message processor,
    * first convert to a structure that ZCL can process.
    */
    afMsg.groupId = pInMsg->groupID;
    afMsg.clusterId = pInMsg->clusterId;
    afMsg.srcAddr.endPoint = pInMsg->srcAddr.endpoint;
    afMsg.srcAddr.panId = pInMsg->srcAddr.panID;
    afMsg.srcAddr.addrMode = (afAddrMode_t)pInMsg->srcAddr.addrMode;
    if( (afMsg.srcAddr.addrMode == afAddr16Bit)
    || (afMsg.srcAddr.addrMode == afAddrGroup)
    || (afMsg.srcAddr.addrMode == afAddrBroadcast) )
    {
    afMsg.srcAddr.addr.shortAddr = pInMsg->srcAddr.addr.shortAddr;
    }
    else if(afMsg.srcAddr.addrMode == afAddr64Bit)
    {
    OsalPort_memcpy(afMsg.srcAddr.addr.extAddr, &(pInMsg->srcAddr.addr.extAddr), 8);
    }
    afMsg.macDestAddr = pInMsg->macDestAddr;
    afMsg.endPoint = pInMsg->endpoint;
    afMsg.wasBroadcast = pInMsg->wasBroadcast;
    afMsg.LinkQuality = pInMsg->linkQuality;
    afMsg.correlation = pInMsg->correlation;
    afMsg.rssi = pInMsg->rssi;
    afMsg.SecurityUse = pInMsg->securityUse;
    afMsg.timestamp = pInMsg->timestamp;
    afMsg.nwkSeqNum = pInMsg->nwkSeqNum;
    afMsg.macSrcAddr = pInMsg->macSrcAddr;
    afMsg.radius = pInMsg->radius;
    afMsg.cmd.DataLength = pInMsg->n_payload;
    afMsg.cmd.Data = pInMsg->pPayload;

    zcl_ProcessMessageMSG(&afMsg);
    }

    万分感谢！！！ 那么终端节点怎样获取其父节点（协调器或路由器）的rssi值呢？有没有相关教程？

    可以在afBuildMSGIncoming內取用MSGpkt->LinkQuality去轉換成RSSI

    可以加在这里面吗？
