zigbee zcl规范及其协议栈实现3 读取服务器端属性值

zigbee zcl规范及其协议栈实现2
中有介绍 对通用命令的处理，按照那个思路和信息流程添加读取服务器端属性值的功能

客户端samplesw想要知道与自己的12号端点SAMPLESW_ENDPOINT 绑定的那个节点samplelight（的13号端点）的硬件版本和厂商名字，这两个属性zcl都有规定，

属于zcl general 的ZCL_CLUSTER_ID_GEN_BASIC

A

1.首先服务器samplelight端需要配置这个属性，代码中已经写过，位于

函数zclSampleLight_Init里注册了属性表，

zcl_registerAttrList( SAMPLELIGHT_ENDPOINT, SAMPLELIGHT_MAX_ATTRIBUTES, zclSampleLight_Attrs );

属性表zclSampleLight_Attrs 配置了属性ATTRID_BASIC_ZCL_VERSION和ATTRID_BASIC_MANUFACTURER_NAME，属于ZCL_CLUSTER_ID_GEN_BASIC

{

ZCL_CLUSTER_ID_GEN_BASIC,

{ // Attribute record

ATTRID_BASIC_ZCL_VERSION,

ZCL_DATATYPE_UINT8,

ACCESS_CONTROL_READ,

(void *)&zclSampleLight_ZCLVersion

}

},

{

ZCL_CLUSTER_ID_GEN_BASIC,

{ // Attribute record

ATTRID_BASIC_MANUFACTURER_NAME,

ZCL_DATATYPE_CHAR_STR,

ACCESS_CONTROL_READ,

(void *)zclSampleLight_ManufacturerName

}

},

2. InClusters里必须添加对clusterid ZCL_CLUSTER_ID_GEN_BASIC的支持

#define ZCLSAMPLELIGHT_BINDINGLIST 2

static cId_t bindingInClusters[ZCLSAMPLELIGHT_BINDINGLIST] =

{

ZCL_CLUSTER_ID_GEN_ON_OFF,

ZCL_CLUSTER_ID_GEN_BASIC

};

3 .在申请绑定搞定的时候，使用bindingInClusters作为参数，代码中已经实现

ZDP_EndDeviceBindReq( &dstAddr, NLME_GetShortAddr(),

SAMPLELIGHT_ENDPOINT,

ZCL_HA_PROFILE_ID,

ZCLSAMPLELIGHT_BINDINGLIST,
bindingInClusters,

0, NULL, // No Outgoing clusters to bind

TRUE );

B

1.客户端samplesw使用与服务器对应的cluster列表

#define ZCLSAMPLESW_BINDINGLIST 2

static cId_t bindingOutClusters[ZCLSAMPLESW_BINDINGLIST] =

{

ZCL_CLUSTER_ID_GEN_ON_OFF,

ZCL_CLUSTER_ID_GEN_BASIC

};

2.在申请绑定的时候使用bindingOutClusters作为参数，代码中已经实现

dstAddr.addrMode = afAddr16Bit;

dstAddr.addr.shortAddr = 0; // Coordinator makes the match

ZDP_EndDeviceBindReq( &dstAddr, NLME_GetShortAddr(),

SAMPLESW_ENDPOINT,

ZCL_HA_PROFILE_ID,

0, NULL, // No incoming clusters to bind

ZCLSAMPLESW_BINDINGLIST,bindingOutClusters,

TRUE );

3.在某个地方执行以下代码，即申请读取zclSampleSw_DstAddr的下面两个属性 (zcl_SendRead()中会自动指定ZCL_FRAME_TYPE_PROFILE_CMD)

zclReadCmd_t readcmd;

ZStatus_t st;

readcmd.numAttr=2;

readcmd.attrID[0]=ATTRID_BASIC_ZCL_VERSION;

readcmd.attrID[1]=ATTRID_BASIC_MANUFACTURER_NAME;

st= zcl_SendRead( SAMPLESW_ENDPOINT, &zclSampleSw_DstAddr,

/*ZCL_CLUSTER_ID_GEN_ON_OFF*/ZCL_CLUSTER_ID_GEN_BASIC, &readcmd,

ZCL_FRAME_CLIENT_SERVER_DIR, false, 0 );

C

服务器会收到信息，触发zclCmdTable[ZCL_CMD_READ]函数即zclProcessInReadCmd函数，此函数自动读取相关属性返回给客户端,通过函数zcl_SendReadRsp()，命令是ZCL_CMD_READ_RSP

D

客户端，samplesw收到信息后触发zclCmdTable[ZCL_CMD_READ_RSP]函数即zclSendMsg函数，此函数会将这个消息以ZCL_INCOMING_MSG事件发给上层任务去处理,前提是上层任务使用zcl_registerForMsg注册过，而在samplesw在init中已经注册过。

在客户端，samplesw任务中处理之

case ZCL_INCOMING_MSG:

// Incoming ZCL Foundation command/response messages

zclSampleSw_ProcessIncomingMsg( (zclIncomingMsg_t *)MSGpkt );->zclSampleSw_ProcessInReadRspCmd

break;

//属性返回处理
static uint8 zclSampleSw_ProcessInReadRspCmd( zclIncomingMsg_t *pInMsg )
{
zclReadRspCmd_t *readRspCmd;
uint8 i;

readRspCmd = (zclReadRspCmd_t *)pInMsg->attrCmd;
for (i = 0; i < readRspCmd->numAttr; i++)
{
uint8 str[6];
// Notify the originator of the results of the original read attributes
// attempt and, for each successfull request, the value of the requested
// attribute
/*
if(i==0)
{
uint8  ii=*readRspCmd->attrList[i].data;
_itoa(ii,str,10);
HalLcdWriteString(str,2);
}
*/
if(i==1)
{
uint8* pp=readRspCmd->attrList[i].data;
HalLcdWriteString(pp,2);
}
}
return TRUE;
}
