CCS/LAUNCHXL-CC26X2R1: Send message and know clusters

Yes, he read most of the documentation. I have already activated the MT interface and the network created, I have also read the ZCL documentation, but I still don't know how to use the AF_DATA_REQUEST command, I don't get an answer from the end-device, I would like to have an example, or know how I can send / receive own messages and for example turn on / off the led as with the APP_MENU, I executed the command ZDO_SIMPLE_DESC_REQ and the following appears to me 

<TX>10:16:10.99 COM6 ZDO_SIMPLE_DESC_REQ (0x2504)
DstAddr: 0x73E4
NWKAddrOfInterest: 0x73E4

Thanks Ryan for your help, I understand what you are telling me, I would like to have some reference on how the packages are formed as you mentioned, I have read ZCL specification, but I cannot find clear examples to interact with the zc_sw/zc_light application, where could I see examples of frames for different applications)? Thanks.

I tried to execute the following command, but I don't see any change in the led of the end-device, I understand that the cluster for on/off is 0x0006, I don't know what I'm doing wrong

<TX>10:28:33.43 COM6 AF_DATA_REQUEST (0x2401)

DstAddr: 0x73E4
DestEndpoint: 0x01
SrcEndpoint: 0x08
ClusterID: 0x0006

Radius: 0x00

Shouldn't your DestEndpoint be 0x08 in accordance with your Simple Descriptor Response?  I also recommend that your Radius be greater than 0.  You should be providing sniffer logs to better understand what is happening over-the-air.

Regards,
Ryan

I also think it should be DestEndpoint = 0x08, but there is an error placing it as a parameter, this appears to me

<TX>10:28:19.48 COM6 AF_DATA_REQUEST (0x2401)
DstAddr: 0x73E4
DestEndpoint: 0x08
SrcEndpoint: 0x01

<RX>10:28:19.49 COM6 AF_DATA_REQUEST_SRSP (0x6401)
Status: afStatus_INVALID_PARAMETER (0x2)

But why are you now using a ScrEndpoint of 0x01 instead of 0x08?  Which endpoints are registered on your MT-enabled device?

Regards,
Ryan

Should I use 0x08 in DstAdrr and SrcAddr? I only have one device registered, an end-device with zed_light, execute the following commands but I don't get any response, What's wrong with the frame?

<TX>11:08:06.08 COM6 UTIL_GET_DEVICE_INFO (0x2700)

How often is the ZED polling?  Try using a TransID greater than 0 but I doubt this will make a difference.  I can only provide further assistance with a sniffer log.

Regards,
Ryan

I'm not sure how to know about polling of ZED, this happens when I execute the command

Each "Data Request" is a ZED poll which appears to be every three seconds, this is acceptable.  I am interested in the packet from the ZC at 19.881838 and the ZED response at 19.891810.  Please provide the sniffer file, not a screenshot.

Regards,
Ryan

Ok, I understand, I attached the link of the sniffer file, I could not upload it here, with which other command of AF_DATA_REQUEST could check that some message arrives

The packets are encrypted, I need the NWK keys or a sniffer log including the ZED joining process.  We are basically attempting to determine whether the ZED returns a success or fail default response.

Regards,
Ryan

The key of Wireshark is 5a6967426565416c6c69616e63653039, Is it the key you need? Or how can I send you the sniffer log?

That's the Trust Center Link Key, I need the Network Key.  I can access and open the sniffer log, I'm just not able to read the encrypted packets.  Chances are you cannot decrypt them either without the device joining procedure.

Regards,
Ryan

how can i know this key?

Join a device to the network with the sniffer turned on so that it can pick up the ZC transport key packet.

Regards,
Ryan

I already did it, but I don't know exactly what is the package where the device comes in, this appears to me

Can you attach sniffer log instead of screenshot?

this is the file of sniffer

https://drive.google.com/file/d/1O7nvQXQVlQZZL5JWeyvhCTOuApxY6kWI/view

I'm not seeing a join inside the 29 packets provided in the last sniffer log, just beacon requests/responses and link status messages.  This does not provide any assistance with the issue.

If you cannot provide a decrypted sniffer log then perhaps you can debug the ZED for the incoming ZCL message since we know that the packet makes it to the end node given that a response is returned.

Regards,
Ryan

Hi Jose,

Can you provide any updates on this matter or can the thread be closed?

Regards,
Ryan

Hi Ryam, finally I could not send/receive data, although I tried to verify the commands with the sniffer, I read the documentation of ZCL and MT interface, but I cannot understand how I should send the payload with AF_DATA_REQUEST, I have not found the version ZCL Revision 7, although I don't think the matter changes.

Since I have gotten a similar application to work with my own setup, I can only further assist if you provide more debug information.  This includes a full system description, Z-Tool commands with parameters included, sniffer logs, and device debugging investigation results.

Regards,
Ryan

I already managed to send data with AF_DATA_REQUEST, the error was indeed the frames that were poorly constructed, now I understand a little more the operation of the clusters, my application consists of a coordinator as a central node that will process data of multiple end-devices, the coordinator has it configured with the ZNP and it works fine, but I have some doubts about sending data.

1. Is necessary for the coordinator to have the same clusters as the end-device for receiving information?
2. Is necessary to do F&B to report attributes from some end-device?
3. I need to send some data periodically from the end-device, that is, for example (temperature, on/off state), I have tried with zstack_report_cmdEx and with AfDataRequest, the messages travel through the air, but do not reach on ZNP, Is there an example of sending data periodically different from zed/zer_light reporting?

Thanks

How to i create a timer for periodic AfDataRequests? is there any example to guide me?

I recommend you refer to the example projects, start from zclSample[application]_initializeClocks

Regards,
Ryan

This is the example I use, how can I add my function that sends data? I created a function that sends the data with afrequest(), how could it add it to a clock?

static void zclSampleLight_initializeClocks(void){

#if ZG_BUILD_ENDDEVICE_TYPE
// Initialize the timers needed for this application
EndDeviceRejoinClkHandle = Timer_construct(
&EndDeviceRejoinClkStruct,
zclSampleLight_processEndDeviceRejoinTimeoutCallback,
SAMPLEAPP_END_DEVICE_REJOIN_DELAY,
0, false, 0);
#endif
#ifdef ZCL_LEVEL_CTRL
LevelControlClkHandle = Timer_construct(
&LevelControlClkStruct,
zclSampleLight_processLevelControlTimeoutCallback,
100,
0, false, 0);
#endif

Should I build something like this? Should the function send the data be called in zclSampleLight_processEndDeviceRejoinTimeoutCallback? 

#if ZG_BUILD_ENDDEVICE_TYPE
// Initialize the timers needed for this application
EndDeviceRejoinClkHandle = Timer_construct(
&EndDeviceRejoinClkStruct,
zclSampleLight_processEndDeviceRejoinTimeoutCallback,
SAMPLEAPP_END_DEVICE_REJOIN_EVT ,
0, false, 0);
#endif

.....

The timer would start like this?

 Timer_start(&EndDeviceRejoinClkStruct);

Thanks.

Can you help me build the event? that is, I should create a new event something like

#define SEND_DATA_EVT 0x0004

My function that sends data is as follows

static void data_send_AF (void)
{
     zstack_getZCLFrameCounterRsp_t pRsp;
     Zstackapi_getZCLFrameCounterReq (appServiceTaskId, & pRsp);
     zstack_afDataReq_t pReq;
     pReq.dstAddr.addrMode = zstack_AFAddrMode_SHORT;
     pReq.dstAddr.addr.shortAddr = 0;
     pReq.dstAddr.endpoint = 8;
     pReq.pRelayList = NULL;
     pReq.n_relayList = 0;
     pReq.srcEndpoint = SAMPLELIGHT_ENDPOINT;
     pReq.clusterID = 0x0006;
     pReq.transID = & (pRsp.zclFrameCounter);
     pReq.radius = AF_DEFAULT_RADIUS;
     pReq.n_payload = 0x6;
     pReq.pPayload = ownData;
     Zstackapi_AfDataReq (appServiceTaskId, & pReq);
}

How can I add this function to zclSampleLight_processEndDeviceRejoinTimeoutCallback and schedule the time it should run?

YK was not suggesting that you directly use/replace zclSampleLight_processEndDeviceRejoinTimeoutCallback and SAMPLEAPP_END_DEVICE_REJOIN_EVT.  You can use 0x0100 as a new event and you should set up your own timer callback accordingly, using the ones already in place as an example.

Regards,
Ryan

Ok, I understand, i haved created the code as follow but the data only is sent one time each time that i press the button and not periodicly, where this error?

#define SAMPLEAPP_SEND_DATA_EVT 0x0100

#define SEND_DATA_TIME  5000

SendDataClkHandle = Timer_construct(
&SendDataClkStruct,
zclSampleLight_sendDataTimeoutCallback,
SEND_DATA_TIME,
0, false, 0);

static void zclSampleLight_sendDataTimeoutCallback(UArg a0)
{
(void)a0; // Parameter is not usedappServiceTaskEvents |= SAMPLEAPP_SEND_DATA_EVT;

Semaphore_post(appSemHandle);

}

In process loop...

if ( appServiceTaskEvents & SAMPLEAPP_SEND_DATA_EVT )
{
zclSampleLight_SendDataAF();

appServiceTaskEvents &= ~SAMPLEAPP_SEND_DATA_EVT;

}

For active timer...

static void zclSampleLight_ActiveTimer(void){

Timer_setTimeout( SendDataClkHandle, SEND_DATA_TIME);
Timer_start(&SendDataClkStruct);

}

and for init the timer

if(_btn == CONFIG_BTN_RIGHT)
{
//zclSampleLight_SendDataAF();
zclSampleLight_ActiveTimer();
}

Hi YK,

Another option is that they construct the timer with a valid clock period.

Regards,
Ryan

Running Active TImer as YK said in the event, I got it sent data periodically, thanks for your support
