假如协调器从串口收到了终端子设备的长地址，可以直接给该终端发送消息吗 ，该从哪儿着手改代码呢？

我先试着把空中来的数据，改成64bit输出到串口看看，从下面这个ZDApp.c来看，是ZDP_IncomingData函数收到了数据，
void ZDApp_ProcessOSALMsg( osal_event_hdr_t *msgPtr )
{
// Data Confirmation message fields
uint8 sentEP; // This should always be 0
uint8 sentStatus;
afDataConfirm_t *afDataConfirm;
uint8 tmp;

switch ( msgPtr->event )
{
// Incoming ZDO Message
case AF_INCOMING_MSG_CMD:
ZDP_IncomingData( (afIncomingMSGPacket_t *)msgPtr );
break;

case ZDO_CB_MSG:
ZDApp_ProcessMsgCBs( (zdoIncomingMsg_t *)msgPtr );
break;

case AF_DATA_CONFIRM_CMD:
// This message is received as a confirmation of a data packet sent.
// The status is of ZStatus_t type [defined in NLMEDE.h]
// The message fields are defined in AF.h
afDataConfirm = (afDataConfirm_t *)msgPtr;
sentEP = afDataConfirm->endpoint;
sentStatus = afDataConfirm->hdr.status;
...
}

然后再跳到这个函数，就不知道改哪儿了

void ZDP_IncomingData( afIncomingMSGPacket_t *pData )
{
uint8 x = 0;
uint8 handled;
zdoIncomingMsg_t inMsg;

inMsg.srcAddr.addrMode = Addr16Bit;
inMsg.srcAddr.addr.shortAddr = pData->srcAddr.addr.shortAddr;
osal_memcpy(inMsg.srcAddr.addr.extAddr, pData->srcAddr.addr.extAddr, 8); //zjt
inMsg.wasBroadcast = pData->wasBroadcast;
inMsg.clusterID = pData->clusterId;
inMsg.SecurityUse = pData->SecurityUse;

inMsg.asduLen = pData->cmd.DataLength-1;
inMsg.asdu = pData->cmd.Data+1;
inMsg.TransSeq = pData->cmd.Data[0];
inMsg.macDestAddr = pData->macDestAddr;

handled = ZDO_SendMsgCBs( &inMsg );

#if (defined MT_ZDO_CB_FUNC)
#if !defined MT_TASK
if (zgZdoDirectCB)
#endif
{
MT_ZdoDirectCB( pData, &inMsg );
}
#endif

while ( zdpMsgProcs[x].clusterID != 0xFFFF )
{
if ( zdpMsgProcs[x].clusterID == inMsg.clusterID )
{
zdpMsgProcs[x].pFn( &inMsg );
return;
}
x++;
}

// Handle unhandled messages
if ( !handled )
ZDApp_InMsgCB( &inMsg );
}
