ti 3.0协议栈绑定的理解

user5764532

Other Parts Discussed in Thread: Z-STACK

利用3.0协议栈的绑定的理解：

1. 您好，我说一下我的理解关于绑定的：就是两个节点要绑定的时候必须先满足两个节点的 bdb_ZclType1Clusters[]和 bdb_ZclType2Clusters[]包含的簇必须完全一样（这就等于查找匹配了）。感觉好像有点牵强。寻找匹配应该是端点的描述符匹配啦。求教一下到底是哪里寻找匹配的？

2.然后在根据bdb_zclFindingBindingEpType（）该函数进行判断谁是target谁是ininitor。在调用bdb_StartCommissioning（BDB_COMMISSIONING_MODE_FINDING_BINDING）就可实现绑定了。这样理解对吗？

3.到底绑定的流程是怎么样的。我看了BDB的规范。但是还是没有看见具体的代码实现在哪里？请Ti的大神帮忙解释一下，这个问题困扰我好多天了。最好有代码来说明，感激不尽了

请根据Z-Stack 3.0 Developer's Guide中Finding and Binding章节。

if(bdbAttributes.bdbCommissioningMode & BDB_COMMISSIONING_MODE_FINDING_BINDING)
  {
    bdbCommissioningProcedureState.bdbCommissioningState = BDB_COMMISSIONING_STATE_FINDING_BINDING;
    
    //Is the device on a network?
    if(bdb_isDeviceNonFactoryNew())
    {
      zclAttrRec_t attrRec;

      endPointDesc_t *bdb_CurrEpDescriptor = NULL;

      bdb_CurrEpDescriptor = bdb_setEpDescListToActiveEndpoint();
      
      //If not found endpoint with Identify cluster is found, then report fail
      if(bdb_CurrEpDescriptor == NULL)
      {
        bdb_exitFindingBindingWStatus(BDB_COMMISSIONING_FAILURE);
        return;
      }
      
      if( bdb_CurrEpDescriptorList->epDesc->epType & BDB_FINDING_AND_BINDING_TARGET)  //F&B as Target
      {
        if (zclFindAttrRec( bdb_CurrEpDescriptor->endPoint, ZCL_CLUSTER_ID_GEN_IDENTIFY,
                  ATTRID_IDENTIFY_TIME, &attrRec ) )
        {
          //Set it to at less 180 
          if ( *((uint16*)attrRec.attr.dataPtr) <= BDBC_MIN_COMMISSIONING_TIME )
          {
            *((uint16*)attrRec.attr.dataPtr) = BDBC_MIN_COMMISSIONING_TIME;
             osal_start_timerEx( bdb_TaskID, BDB_IDENTIFY_TIMEOUT, 1000 );

            if(pfnIdentifyTimeChangeCB != NULL)
            {
              if(bdbIndentifyActiveEndpoint == 0xFF)
              {
                pfnIdentifyTimeChangeCB(bdbIndentifyActiveEndpoint);  
              }
              else
              {
                pfnIdentifyTimeChangeCB(bdb_CurrEpDescriptor->endPoint);
              }
            }
          }
          //Attribute found and set, report success
          if(!(bdb_CurrEpDescriptorList->epDesc->epType & BDB_FINDING_AND_BINDING_INITIATOR))
          {
            bdb_exitFindingBindingWStatus(BDB_COMMISSIONING_FB_TARGET_IN_PROGRESS);
          }
          else
          {
            bdbCommissioningModeMsg_t bdbCommissioningModeMsg;

            bdbCommissioningModeMsg.bdbCommissioningMode = BDB_COMMISSIONING_FINDING_BINDING;
            bdbCommissioningModeMsg.bdbCommissioningStatus = BDB_COMMISSIONING_FB_TARGET_IN_PROGRESS;

            bdb_NotifyApp((uint8*)&bdbCommissioningModeMsg);
          }
        }
        else
        {
          //Attribute not found and no initiator process, report fail
          if(!(bdb_CurrEpDescriptorList->epDesc->epType & BDB_FINDING_AND_BINDING_INITIATOR))
          {
            bdb_exitFindingBindingWStatus(BDB_COMMISSIONING_FAILURE);
          }
        }
      }  //F&B Target
      
      if( bdb_CurrEpDescriptorList->epDesc->epType & BDB_FINDING_AND_BINDING_INITIATOR)  //F&B as Initiator
      {
        bdbCommissioningModeMsg_t bdbCommissioningModeMsg;
        
        //If no function to add binds is available then do not process Initiator
        if(!pbindAddEntry)
        {
          //If no target process, then report fail
          if(!(bdb_CurrEpDescriptorList->epDesc->epType & BDB_FINDING_AND_BINDING_TARGET))
          {
            bdb_exitFindingBindingWStatus(BDB_COMMISSIONING_FAILURE);
          }        
        }
        else
        {
          //Send identify query with the endpoint requested
          if(bdb_SendIdentifyQuery(bdb_CurrEpDescriptor->endPoint) != ZSuccess)
          {
            bdb_exitFindingBindingWStatus(BDB_COMMISSIONING_FAILURE);
          }

          //If periodic F&B is enabled
          if ( FINDING_AND_BINDING_PERIODIC_ENABLE == TRUE )
          {
            // total F&B time will be at least BDBC_MIN_COMMISSIONING_TIME, and at most (BDBC_MIN_COMMISSIONING_TIME + FINDING_AND_BINDING_PERIODIC_TIME - 1)
            bdb_FB_InitiatorCurrentCyclesNumber = (BDBC_MIN_COMMISSIONING_TIME + (FINDING_AND_BINDING_PERIODIC_TIME - 1)) / FINDING_AND_BINDING_PERIODIC_TIME;
            
            osal_start_timerEx(bdb_TaskID, BDB_FINDING_AND_BINDING_PERIOD_TIMEOUT, FINDING_AND_BINDING_PERIODIC_TIME * 1000);
          }

          bdbCommissioningModeMsg.bdbCommissioningMode = BDB_COMMISSIONING_FINDING_BINDING;
          bdbCommissioningModeMsg.bdbCommissioningStatus = BDB_COMMISSIONING_FB_INITITATOR_IN_PROGRESS;

          bdb_NotifyApp((uint8*)&bdbCommissioningModeMsg);
        }
      } //F&B Initiator
    }
    //Not in the network
    else
    {
      bdb_exitFindingBindingWStatus(BDB_COMMISSIONING_FAILURE);
    }

根据这个去梳理。
