【经验】EmberZnet如何调用自定义API实现Zigbee数据上报？

SILICON LABS的Zigbee设备工作时有一个非常重要的功能即状态同步，通常需要同步的数据，包括传感器的数据，球泡灯的开关/颜色状态，开关面板的开关状态等；那么这些数据时如何发送给目标设备（网关）的呢？我们可以参考《【经验】利用CLI命令创建EFR32MG的Zigbee工程绑定和上报条目》使用 CLI 来实现标准的上报流程，这中间需要执行绑定和上报配置等操作，那么有没有办法直接自己构造命令并随时上报你要的数据呢？

下面的函数参考 conditionreport 的处理，对自定义的数据包进行封装并发送：

extern EmberApsFrame globalApsFrame;

//code:

/**

*   General report message composition EX

*   uint8 u8AttrNums    --- need to report attr Num

*   AttrID   --- AttrID[1] = XXX; AttrID[2] = XXX;

*/

uint8_t UserReportSpecificAttributeEx(

    uint16_t

    u16ClusterID,

    uint8_t

    u8AttrNums,

    uint16_t    *u16AttrID,

    uint8_t                     u8SrcEndPoint,

    uint8_t                     u8DestEndPoint,

    uint16_t                   ManufacturerCode)

{

    uint8_t Data[50];

    uint8_t ZCL_Data[90];

    uint16_t ZclBufferLen = 0;

    EmberStatus status = EMBER_SUCCESS;

    globalApsFrame.clusterId = u16ClusterID;

    globalApsFrame.destinationEndpoint = u8DestEndPoint;

    globalApsFrame.sourceEndpoint = u8SrcEndPoint;

    globalApsFrame.profileId = 0x0104;//HA

    uint16_t mfgSpecificId = ManufacturerCode;

    uint8_t disableDefaultResponse = 1;

    EmberAfAttributeType type;

    uint8_t index = 0;

    uint8_t i1;

//zcl common header

    ZCL_Data[index++] = (ZCL_GLOBAL_COMMAND

                         | ZCL_FRAME_CONTROL_SERVER_TO_CLIENT

                         | (mfgSpecificId != EMBER_AF_NULL_MANUFACTURER_CODE

                            ? ZCL_MANUFACTURER_SPECIFIC_MASK

                            : 0)

                         | (disableDefaultResponse

                            ? ZCL_DISABLE_DEFAULT_RESPONSE_MASK

                            : 0));

    if (mfgSpecificId != EMBER_AF_NULL_MANUFACTURER_CODE)

    {

        ZCL_Data[index++] = (uint8_t)mfgSpecificId;

        ZCL_Data[index++] = (uint8_t)(mfgSpecificId >> 8);

    }

    ZCL_Data[index++] = emberAfNextSequence();

    ZCL_Data[index++] = ZCL_REPORT_ATTRIBUTES_COMMAND_ID;

    ZclBufferLen = index;

    for( i1=0; i1<u8AttrNums; i1++ )

    {

        status =    emAfReadAttribute(u8SrcEndPoint,

                                      (EmberAfClusterId)u16ClusterID,

                                      (EmberAfAttributeId)u16AttrID[i1],

                                      CLUSTER_MASK_SERVER,

                                      mfgSpecificId,

                                      Data,

                                      sizeof(Data),

                                      &type);

        if (status != EMBER_ZCL_STATUS_SUCCESS)

        {

            emberAfCorePrintln("ERR:APP_eUserReportSpecificAttributeEx %x", status);

            return  status;

        }

        ZCL_Data[ZclBufferLen] = LOW_BYTE(u16AttrID[i1]);

        ZclBufferLen += 1;

        ZCL_Data[ZclBufferLen] = HIGH_BYTE(u16AttrID[i1]);

        ZclBufferLen +=1;

        ZCL_Data[ZclBufferLen] = type;

        ZclBufferLen +=1;

        uint16_t  size = (emberAfIsThisDataTypeAStringType(type)

                          ? emberAfStringLength(Data) + 1

                          : emberAfGetDataSize(type));

        MEMMOVE( ZCL_Data+ZclBufferLen, Data, size);

        ZclBufferLen += size;

        MEMSET(Data, 0, 50);

    }

    uint8_t mode ;

    mode = EMBER_OUTGOING_DIRECT;

    status = emberAfSendUnicast(EMBER_OUTGOING_DIRECT,

                                0x0000,

                                &globalApsFrame,

                                ZclBufferLen,

                                ZCL_Data);

    emberAfAppPrintln("Report>>%s u16ClusterID: %04x, SeqNum: %d, status: %d\n",__FUNCTION__, u16ClusterID,ZCL_Data[3], status);

    return status;

}

上述函数可以在任何时间发送 report 命令给任意设备，方便进行自定义发送。
