怎样配置一个TouchLink Target?

预编译BDB_TOUCHLINK_CAPABILITY_ENABLED == TRUE

你可以去看一下ZR Light (touchlink target) and ZR Switch (touchlink initiator)

启动设置为bdb_StartCommissioning(BDB_COMMISSIONING_MODE_INITIATOR_TL);

然后去追踪程序：

#if ( defined ( BDB_TL_INITIATOR ) && (BDB_TOUCHLINK_CAPABILITY_ENABLED == TRUE) )
  if(bdbAttributes.bdbCommissioningMode & BDB_COMMISSIONING_MODE_INITIATOR_TL)
  {
    uint16 nwkAddr;

    //Does the device supports this commissioning mode?
    if(bdbAttributes.bdbNodeCommissioningCapability & BDB_TOUCHLINK_CAPABILITY)
    {
      //Clear previous state and substates
      osal_memset(&bdbCommissioningProcedureState,0,sizeof(bdbCommissioningProcedureState));
      bdbCommissioningProcedureState.bdbCommissioningState = BDB_COMMISSIONING_STATE_TL;
      
      // Get our short address
      ZMacGetReq( ZMacShortAddress, (byte*)&nwkAddr );

      // Check if address is invalid
      if ( nwkAddr >= NWK_BROADCAST_SHORTADDR_DEVZCZR )
      {
        initiatorSelectNwkParams();
      }
      
      touchLinkInitiator_StartDevDisc( );  
      
      bdb_NotifyCommissioningModeStart(BDB_COMMISSIONING_TOUCHLINK);
    }

上面的程ZR Light (touchlink target) and ZR Switch (touchlink initiator)中callback已经写好了，具体流程去看Z-Stack 3.0 Developer's Guide

抓包又发出吗？没有response？

在touchLinkTargetApp_Init中注册了 bdbTL_RegisterInterPANCmdCallbacks(&touchLinkTarget_CmdCBs);

这个回调最后出去rsp。

static ZStatus_t targetNwkStartReqCB( afAddrType_t *srcAddr, bdbTLNwkStartReq_t *pReq, uint8 seqNum )
{
#if ZSTACK_END_DEVICE_BUILD
  return ( ZFailure );
#else
  if ( touchLink_IsValidTransID( pReq->transID ) == FALSE )
  {
    return ( ZFailure );
  }
  
  dstAddr = *srcAddr;
  dstAddr.panId = 0xFFFF;

  zstack_tlTargetNwkStartReq_t *pTargetNwkStartReq;
  pTargetNwkStartReq = (zstack_tlTargetNwkStartReq_t*)zcl_mem_alloc( sizeof(zstack_tlTargetNwkStartReq_t) );

  zcl_memcpy(&(pTargetNwkStartReq->addr), &dstAddr, sizeof(afAddrType_t));
  zcl_memcpy(&(pTargetNwkStartReq->nwkStartReq), pReq, sizeof(bdbTLNwkStartReq_t));
  pTargetNwkStartReq->seqNum = seqNum;
  pTargetNwkStartReq->allowStealing = touchlinkAppAllowStealing;

  Zstackapi_tlTargetNwkStartReqInd(tlAppEntity, pTargetNwkStartReq);
  zcl_mem_free(pTargetNwkStartReq);

  return ( ZSuccess );
#endif
}

zstack_ZStatusValues Zstackapi_tlTargetNwkStartReqInd(

   ICall_EntityID appEntity, zstack_tlTargetNwkStartReq_t *pReq)

{

   // Build and send the message, then wait of the response message

   return( sendReqDefaultRsp(appEntity, zstackmsg_CmdIDs_TL_TARGET_NWK_START_REC_IND,

                             pReq, sizeof(zstackmsg_tlTargetNwkStartReq_t),

                             matchTLTargetNetworkStartReqInd) );

}

你用的是我让你用的那个两个ZR程序？

Target 收到req后到了这里，但 抓包没发现scan Response

static ZStatus_t targetScanReqCB( afAddrType_t *srcAddr, bdbTLScanReq_t *pReq, uint8 seqNum )

{

 ZStatus_t ret = ZSuccess;

 int8 rssi;

 char buff[4];

 extern void HalLcdWriteStringValue( char *title, uint32 value, uint8 format, uint8 line );

 extern void HalLcdWriteString ( char *str, uint8 option);

 HalLcdWriteStringValue("TL_I", pReq->touchLinkInitiator,10, 1);

 if( pReq->touchLinkInitiator == FALSE )

 {

   return ZFailure;

 }

 rssi = touchLink_GetMsgRssi();

 sprintf(buff, "%d", rssi);

 HalLcdWriteString(buff,  2);

 if( rssi > TOUCHLINK_WORST_RSSI )

 {

   if ( pDiscoveredNwkParamList == NULL )

   {

     dstAddr = *srcAddr;

     dstAddr.panId = 0xFFFF;

     ret = touchLink_TargetSendScanRsp( TOUCHLINK_INTERNAL_ENDPOINT, &dstAddr, pReq->transID, seqNum );

     if ( ret == ZSuccess )

     {

       touchLinkTransID = pReq->transID;

     }

   }

 }

 HalLcdWriteStringValue("ret", ret, 10, 3);

 return ( ret ); //返回0

}

我大致说一下，我这边是可以的，因为没带PC只能用Wireshark抓包就不上传了。

TARGET:

           zstack_bdbStartCommissioningReq.commissioning_mode =

       BDB_COMMISSIONING_MODE_NWK_STEERING|BDB_COMMISSIONING_MODE_NWK_FORMATION;

           Zstackapi_bdbStartCommissioningReq(zclSampleLight_Entity,&zstack_bdbStartCommissioningReq);

           touchLinkTarget_EnableCommissioning( TOUCHLINK_TARGET_PERPETUAL);

BDB_TL_INITIATOR ：

zstack_bdbStartCommissioningReq_t zstack_bdbStartCommissioningReq;

       zstack_bdbStartCommissioningReq.commissioning_mode = BDB_COMMISSIONING_MODE_INITIATOR_TL;

       Zstackapi_bdbStartCommissioningReq(zclSampleSw_Entity,&zstack_bdbStartCommissioningReq);

您好，我昨天先让Router（Touchlink target）建立一个网络后，再让EndDevice（initiator）发送scan request，Router有回应，并且到了Identity这个流程，但是没有到Network Join这里；BDB文档和Sample文档里说target收到network start  request才建立网络也可以的啊。

target(router) response 后就没反应了

CC2530，板子已经很近了， RSSI = -27, Initiator(EndDevice)发出的scan request如下

你好，能不能把你的抓包发我一下？我现在到了network start request这个步骤

ZLL 是 light switch的程序。

请见:https://e2e.ti.com/support/wireless_connectivity/zigbee_6lowpan_802-15-4_mac/f/158/t/706202

追踪代码返现Target（Router ）建立新网络后并没有按照Z-Stack 3.0 Sample Application User's Guide.pdf中所展示的流程(如图)给

Initiator（EndDevice）发送Network start respons，而是通过NLME_DirectJoinRequestWithAddr（）函数请求Initiator入网，但是返回值却是ZNwkAlreadyPresent          0xc5，也没有抓到任何数据包，估计是没有发数据出来。

如果你使用CC2530添加BDB_TL_TARGET及INTER_PAN到SampleLigth router應該是會編譯失敗，檢查看看你是不是為了優化內存使用移除了一些程序造成問題？因為CC2530內存限制，比較建議你用CC2538或是最新的CC2652測試touchlink

你好，我屏蔽了一些不需要的功能，现在Router(Target)正常，但是EndDevice（Initiator）不正常，基本上每次Rejoin后PanID都会变，只有少数是成功的。

EndDevice（Initiator）不正常，基本上每次Rejoin后PanID都会变

這還是要你自己檢查看看有沒有改動了什麼不該改動的地方了
