[参考译文] SIMPLELINK-CC13X2-26X2-SDK：使用 SimpleLink 6.30.00.84读取属性时因 software_failure 而失败

尊敬的 Koen：

您可以查看对 zcl.c 所做的更改、该更改会影响您描述的行为。

//V6.30
    //Validate the attribute is found and the access control
    if ( ( attrFound == TRUE ) &&
         (  (attrRec.attr.accessControl & ACCESS_GLOBAL) ||
            (GET_BIT( &attrRec.attr.accessControl, ACCESS_CONTROL_MASK ) == pInMsg->hdr.fc.direction ) ) )
    {
      if ( zcl_AccessCtrlRead( attrRec.attr.accessControl ) )
      {
        if ( zcl_AccessCtrlAuthRead( attrRec.attr.accessControl ))
        {
          statusRec->status = zclAuthorizeRead( pInMsg->msg->endPoint,
                                                        &(pInMsg->msg->srcAddr), &attrRec );
        }
        else
        {
          statusRec->status = zclReadAttrDataUsingCB( pInMsg->msg->endPoint, attrRec.clusterID, attrRec.attr.attrId, attrRec.attr.dataPtr, &len );
        }

//V6.20
    //Validate the attribute is found and the access control
    if ( ( attrFound == TRUE ) &&
         (  (attrRec.attr.accessControl & ACCESS_GLOBAL) ||
            (GET_BIT( &attrRec.attr.accessControl, ACCESS_CONTROL_MASK ) == pInMsg->hdr.fc.direction ) ) )
    {
      if ( zcl_AccessCtrlRead( attrRec.attr.accessControl ) )
      {
        statusRec->status = zclAuthorizeRead( pInMsg->msg->endPoint,
                                              &(pInMsg->msg->srcAddr), &attrRec );

 除了给定的 ZCL_STATUS_SOFTWARE_FAILURE 状态(由于未注册 pfnReadWriteCB 且 ACCESS_CONTRAL_AUTH_READ 未设置)之外、返回数据包是否与之前相同？  您可以选择恢复更改或将 zclReadAttrDataUsingCB 的返回状态更改为 ZCL_STATUS_SUCCESS、以解决观察到的行为。

此致、
