[zigbee zcl规范及其协议栈实][zigbee zcl] [现2][zigbee zcl]  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;

1.  //属性返回处理
2.  **static** uint8 zclSampleSw\_ProcessInReadRspCmd( zclIncomingMsg\_t \*pInMsg ) 
3.  \{ 
4.   zclReadRspCmd\_t \*readRspCmd; 
5.   uint8 i; 
6.  
7.   readRspCmd = (zclReadRspCmd\_t \*)pInMsg->attrCmd; 
8.  **for** (i = 0; i < readRspCmd->numAttr; i++) 
9.   \{ 
10.  uint8 str\[6\]; 
11. // Notify the originator of the results of the original read attributes
12. // attempt and, for each successfull request, the value of the requested
13. // attribute
14. /\*
15.  if(i==0)
16.  \{ 
17.  uint8 ii=\*readRspCmd->attrList\[i\].data;
18.  \_itoa(ii,str,10);
19.  HalLcdWriteString(str,2);
20.  \}
21.  \*/
22. **if**(i==1) 
23.  \{ 
24.  uint8\* pp=readRspCmd->attrList\[i\].data; 
25.  HalLcdWriteString(pp,2); 
26.  \} 
27.  \} 
28. **return** TRUE; 
29. \} 
30.
