CC2650DK: How to send data using ZCL API

Tonny Sabirin
Intellectual 875 points

Part Number: CC2650DK

Hi All,

I'm using SampleSwitch from zstack_home_1_02_02a_44539 as a base for my project.

now i want to send a data from end point to coordinator, to send the data I'm using 

AF_DataRequest( destAddr, epDesc, clusterID, msgLen, pBuf, &zcl_TransID, options, AF_DEFAULT_RADIUS );

with the data in "pBuf".

but when i see in the sniffer using wireshark, I cannot see the data that i send.

do you know where i'm wrong ? or maybe I'm using incorrect API for the process

Please help me with this.

i set the Source Endpoint to 27 to identified the message.

this is the sniff data

    Your destination endpoint is set to 255 which is incorrect.

    Hi YK,

    I though endpoint 255 is the broadcast endpoint, is that an issue if i want to send data ?
    i haven't manage the endpoint, only want to send the data out correctly first.

    thx for your reply
    regards

    Yes, that is an issue. You have to use a correct endpoint otherwise it won't work.

    Hi YK,

    if my endpoint is coordinator, can i set endpoint value using ztool ?

    thx for your reply

    Hi YK,

    if i use znp-bringup.zjs is this the endpoint config ?
    private var endPoint : Byte = 0x07;

    i still cannot change the destination endpoint in the end node,
    is the sample for SampleSwitch can connect with ZAP-ZNP Coordinator without trouble ? or need modification ?
    maybe i need to reinstall the ZStack Home again if by default the sample should work

    thx for your reply
    regards

    Yes, SampleSwitch can connect with ZAP-ZNP coordinator without problem. I suggest you to use ZDP_ACTIVE_EP_REQ MT command to request endpoint from coordinator to your SampleSwitch.

    Hi YK,

    still need to read some more about endpoint because still fail to set one.

    but if i snif the data using cc2530 and wireshark, the message is encrypted.
    do you know how to send plain message so i can see what data is being sent ?

    thx for your reply
    regards

    Since Zigbee HA use TC link key to transport network key, you have to input your TC link key to make wireshark can decrypt Zigbee HA message.

    Hi YK,

    ah thx for the key info, now i can see the data.

    but i loop AF_DataRequest function, but why no data that being send out ?

    status = AF_DataRequest( destAddr, epDesc, clusterID, msgLen, msgBuf,
    &zcl_TransID, options, AF_DEFAULT_RADIUS );

    I trace step by step and no error occur.
    do you know what is possibly wrong with my coding, what is the function that supposed to send message out ?

    I modify the basic the default "static void Switch_sendToggle(void)" into this

    static void Switch_sendToggle(void)
    {
    zclReportCmd_t *pReportCmd;

    // Build and send a ZCL temperature reading to the matched device
    pReportCmd = ICall_malloc(sizeof(zclReportCmd_t) + sizeof(zclReport_t));
    if(pReportCmd != NULL)
    {
    afAddrType_t dstAddr;

    // Fill in the destination address
    dstAddr.addrMode = (afAddrMode_t)zswDstAddr.addrMode;
    dstAddr.addr.shortAddr = zswDstAddr.addr.shortAddr;
    dstAddr.endPoint = zswDstAddr.endpoint;
    dstAddr.panId = zswDstAddr.panID;

    // Fill in the single attribute information for the temperature reading
    pReportCmd->numAttr = 1;
    pReportCmd->attrList[0].attrID = ATTRID_MS_TEMPERATURE_MEASURED_VALUE;
    pReportCmd->attrList[0].dataType = ZCL_DATATYPE_INT16;
    pReportCmd->attrList[0].attrData = "Hallo"; //(void *) (&staTempMeasuredValue);

    // Call ZCL function to send the report
    zcl_SendReportCmd(SWITCH_EP, &dstAddr,
    ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT, pReportCmd,
    ZCL_FRAME_SERVER_CLIENT_DIR, true, staTransID++);

    ICall_free(pReportCmd);

    thx for your reply

    Hi YK,

    btw my setup only like this :
    CC2650DK (ZED) (SampleSwitch SOC) connect to CC2650DK (ZC) + Ztool ( using znp-bringup.zjs)
    do you have any concern about my setup related to my question

    thx for your reply

    No, I see no problem on your configuration.

    Hi YK,

    after see "zclGeneral_SendIdentifyQuery" function, i see some prerequisite so "zcl_SendCommand" can send a message.
    maybe because of that the Switch_sendToggle failed to send the message, beside the Dest Endpoint is not 255, do you know what is the pre req for "zcl_SendCommand" so it can send the message ?

    like maybe need on certain state or event ?
    certain condition ?

    thx for your reply
    regards

    Hi YK,

    is it correct that i need to successfully mapping a switch to light, before i can successfully send the data using "zclGeneral_SendOnOff_CmdToggle" in the SampleSwitch from "C:\ti\simplelink\zstack_home_1_02_02a_44539\Projects\zstack\HomeAutomation\SampleSwitch" ?

    thx for your reply

    Hi All,

    where is this message below come from ? is it Zstack Core because i cannot trace the source from the sample application,
    when i try to open ZStackCore code there always message pop up say "changing active configuration will terminate the debug session"

    i see you can put breakpoint on ZstackCore, how you do it ?

    1. You have to do binding or know destination short address/endpoint before you can send message from SampleSwitch to SampleLight.
    2. Yes, you can set a breakpoint in ZStackCore but you should debug from application.

    Hi YK,

    yes you are correct previously, the issue is in the endpoint value, it has to be valid value,

    my question now, how we know what is the list of correct EndPoint value, and how to define one if you want to create specific endpoint value ?

    could you refer a document about this 

    this is my sniff with my data broadcast ed, the data is in the payload

    When a device joins Zigbee network, it would broadcast end node announcement which would contains short and IEEE address of device. You can use the short address to request endpoint. If you use ZNP, you can use ZDO_ACTIVE_EP_REQ to request endpoint.

    Hi YK,

    yes I'm using ZNP for the coordinator.
    and after get the endpoint value from ZED i need to register it on the coordinator endpoint table something ?

    Thx for your reply

    No, you should store the endpoint and short address for sending messages using AF_DataRequest.
