You can use sniffer.

That is right but at code side.....???
Please consider following scenario:
I want to sending two 10 bytes of msg one by one
First 10 byte are sended over the air by using AF_DataRequest API...
Before sending next 10 bytes over the air If I want to know that previous data was not sended yet.
So how can I implement that

I suppose you can enable APS ack to make it.

0 Jay Panchal over 8 years ago in reply to YiKai Chen

That means I should wait for APS ack??

Currently I have disabled APS_ACK_REQ by removing it from AF_DATA_REQ
Because when I send multiple bytes of data some were miss beacause I was think that coordinator is wait for AF_DATA confirmation

Where can I do that??

You can enable AF_ACK_REQUEST in AF_DataRequest option and check sequence number in AF_DATA_CONFIRM_CMD.

How to check check sequence number??
Doesn't know about that

0 YiKai Chen over 8 years ago in reply to Jay Panchal

Guru 735695 points

When you call AF_DataRequest, you should give every message a sequence number and you should check it in AF_DATA_CONFIRM_CMD.

I simply transmits data by following function:
just pass buffer and length into that function:

static void DEEPSendToAir(uint16 NETID, uint8 *buff, uint16 length)
{
LED = ~LED;
GenericApp_DstAddr.addrMode = (afAddrMode_t)Addr16Bit;
GenericApp_DstAddr.endPoint = GENERICAPP_ENDPOINT;
GenericApp_DstAddr.addr.shortAddr = NETID;

if ( AF_DataRequest( &GenericApp_DstAddr, &GenericApp_epDesc,GENERICAPP_CLUSTERID,length ,buff,
&GenericApp_TransID,(AF_DISCV_ROUTE | AF_ACK_REQUEST), AF_DEFAULT_RADIUS ) == afStatus_SUCCESS )
{
}
}

GenericApp_TransID is the sequence number.

0 Jay Panchal over 8 years ago in reply to YiKai Chen

Expert 1740 points

You mean I should check in AF_DATA_CONFIRM_CMD that weather received sequence number is same as the transmitted ??
Am I right??

0 YiKai Chen over 8 years ago in reply to Jay Panchal

Guru 735695 points

Yes

0 Jay Panchal over 8 years ago in reply to YiKai Chen

Expert 1740 points

If received sequence number is not same as the transmitted than resending the previous message??
Is that OK??

0 YiKai Chen over 8 years ago in reply to Jay Panchal

Guru 735695 points

Yes, that’s it.

Which is the received sequence number from Incoming Msg.
I think it is nwkSeqNum.
Am I Right??

MSGpkt->hdr.event = AF_INCOMING_MSG_CMD;
MSGpkt->groupId = aff->GroupID;
MSGpkt->clusterId = aff->ClusterID;
afCopyAddress( &MSGpkt->srcAddr, SrcAddress );
MSGpkt->srcAddr.endPoint = aff->SrcEndPoint;
MSGpkt->endPoint = epDesc->endPoint;
MSGpkt->wasBroadcast = aff->wasBroadcast;
MSGpkt->LinkQuality = sig->LinkQuality;
MSGpkt->correlation = sig->correlation;
MSGpkt->rssi = sig->rssi;
MSGpkt->SecurityUse = SecurityUse;
MSGpkt->timestamp = timestamp;
MSGpkt->nwkSeqNum = nwkSeqNum;
MSGpkt->macSrcAddr = aff->macSrcAddr;
MSGpkt->macDestAddr = aff->macDestAddr;
MSGpkt->srcAddr.panId = SrcPanId;
MSGpkt->cmd.TransSeqNumber = 0;
MSGpkt->cmd.DataLength = aff->asduLength;
MSGpkt->radius = radius;

You should add a case “AF_DATA_CONFIRM_CMD” in your zclxxx_event_loop and check transID in MSGpkt.

0 Jay Panchal over 8 years ago in reply to YiKai Chen

Expert 1740 points

Is following is the right way to get sequence number

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 ZComDef.h]
// The message fields are defined in AF.h
#if defined( DEEP_COORDINATOR )
if(MSGpkt->cmd.TransSeqNumber != GenericApp_TaskID)
{

}
#endif
break;

It should be like the following code to get sequence number:

        case AF_DATA_CONFIRM_CMD:
          afDataConfirm_t *RcvafDataConfirm;
          RcvafDataConfirm= (afDataConfirm_t *)MSGpkt;
          sequence number=RcvafDataConfirm->transID;

0 Jay Panchal over 8 years ago in reply to YiKai Chen

Expert 1740 points

this sequence number should be match with the number transmitted in following function GenericApp_TransID ?? If it dosen't match than retransmitt the message am I rigth??

if ( AF_DataRequest( &GenericApp_DstAddr, &GenericApp_epDesc,GENERICAPP_CLUSTERID,data_len,data,

&GenericApp_TransID,(AF_DISCV_ROUTE | AF_ACK_REQUEST),AF_DEFAULT_RADIUS)==afStatus_SUCCESS)

Yes, that’s it.
