CC2652R: Zigbee, difference between zstack_afDataReq_t and the zigbee application defined sendcommand msg OTA

Hamza Kadhum

Part Number: CC2652R

Hi,

I am currently working on implementing an application.

I'm wondering if there is any difference between sending message over the air using zstack_afDataReq_t and the given commands such as "zclGeneral_SendOnOff_CmdToggle"? If I am not mistaken, the commands use similar API to afDataReq to send message? Below is the code I'm currently using to send messages.

I'm working on implementing Cluster ID 0x0B04 ELECTRICAL_MEASUREMENT application to measure analogue value from temp sensor, is there any send message api similar to zclGeneral_sendOnOff_cmdtoggle?

1. zclGeneral_SendOnOff_CmdToggle would use afDataReq in the end. It's just a ZCL API wrapped for easier usage.

2. You can refer to the following code to send temperature report in zed_temperature example to do implementing Cluster ID 0x0B04 ELECTRICAL_MEASUREMENT application accordingly.

          Req.attrID = ATTRID_MS_TEMPERATURE_MEASURED_VALUE;
          Req.cluster = ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT;
          Req.endpoint = SAMPLETEMPERATURESENSOR_ENDPOINT;

          Zstackapi_bdbRepChangedAttrValueReq(appServiceTaskId,&Req);

Hi,

that code seems like it just changes data of the attribute for given cluster id in the ZED, it doesn't send message to e.g. Coordinator, right?

If you do binding before you call the API, it will send report to binding destination. If the binding destination is coordinator, it wi send report to coordinator.

Hi Hamza,

As YK mentioned, you can refer to the temperaturesensor example projects as an example of how to use BDB_REPORTING to your advantage: http://dev.ti.com/tirex/explore/node?a=pTTHBmu__&node=AFreHrkm3qUNjh-9CXNSPg__pTTHBmu__LATEST

I also think this SLA will further assist your understanding of creating binds and sending AF data requests: http://dev.ti.com/tirex/explore/node?node=AJeGnyIqlkquNAYMtLtovQ__pTTHBmu__LATEST&r=pTTHBmu__

Hi,

the guide, are we supposed to define the flags inserted in the code at step 4 in task 1 under zclSampleLight_processZStackMsgs function?
I have skipped those flags because it doesn't say that we should include them.
I have tried this example and guide for a while but it has not worked, thus I am working with ZED -> ZC reporting because I want to report the value from ZED To ZC and It doesn't seem to work.

I really want this method you and YK mention to work because it seems very efficient to use report instead of the code mentioned above.
My trouble now is that I'm following the guide but It's not working, I am currently debugging and will appreciate your assistance.

Regards,
Hamza

Hi Hamza,

You either have to create a manual bind on the ZED electrical measurement device or enable F&B where the ZC has a electrical measurement outgoing cluster registered in order for the reporting to operate successfully. Based on your system description it sounds as though the temperature sensor and thermostat example applications should be used for evaluation and then modified for your specific application needs.

Ryan

Hi,

I have followed the guide with instead ZED and ZC tempsensor. I have configured ZED accordingly to the guide so that ZED reports to ZC. But It is not working, I believe that the issue is on the receiving side, ZC. In the guide, task 3, ZCL_CMD_REPORT should process reports received from the ZED. I set a breakpoint for the switch function to see if it ever go to that case statement but it doesn't.

I use this code to report attribute change;

zstack_bdbRepChangedAttrValueReq_t Req;

Req.attrID = ATTRID_MS_TEMPERATURE_MEASURED_VALUE;
Req.cluster = ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT;
Req.endpoint = SAMPLETEMPERATURESENSOR_ENDPOINT;

Zstackapi_bdbRepChangedAttrValueReq(appServiceTaskId,&Req);

Do you use sniffer to check what happens over the air?

I have ordered and haven't received yet. Will have it probably next week =).

Hamza,

I recommend using a ZED tempsensor and ZC thermostat along with evaluating using the PuTTY UI, the examples should work by default.

Dear Ryan,

Thank you for that example, I have resolved the issue. The ZCL_CMD_REPORT case is working now and I am able to report the temperature, I will continue to build on that.

Regarding zl_<app>_data.c where we define cluster in and out
e.g. out <const cId_t zclSampleTemperatureSensor_OutClusterList>
What is the outcluster respective inclusterlist defining in terms of input/output?
i.e. will the cluster defined inside be an external cluster ID or a cluster that will be outputed to another device?

In the same file we define clusterID multiple times but with different attriID etc..
When we use API similar to zcl_SendReportCmd(.., ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT,..) where I only identify the Cluster ID as input parameter to the send message, how will zigbee interpret it?
Will all clusterID with different attriID be sent and at the receiving end we collect the desired attributeID?

Best regards
Hamza

Hamza,

I recommend that you look at the following SLA and its document citations for a better understanding of the in/out cluster list: http://dev.ti.com/tirex/explore/node?node=AHfY0Eko1oL507RS1aRYoQ__pTTHBmu__LATEST&r=pTTHBmu__

Only the reportable attributes of the desired cluster from a particular endpoint will be sent when using zcl_SendReportCmd. When in doubt, simply run some test cases on your Zigbee devices to see what the APIs accomplish.

Ryan
