how could devices know when binding success？

After received identify query response in ez-mode, it will initiate match descriptor request on the remote node. If the node receives match descriptor response and active clusters match, it means binding success. This is in case EZMODE_ACTION_MATCH_DESC_RSP: of zcl_EZModeAction().

Hi yikai

         i want to turn on the LED when the end device（as a target）binding success。

        as you said ，it will be in case EZMODE_ACTION_MATCH_DESC_RSP：

       so i coding in targe side

   /*********************************************************************
 * @fn      zclSmartplug_ProcessZDOMsgs
 *
 * @brief   Called when this node receives a ZDO/ZDP response.
 *
 * @param   none
 *
 * @return  status
 */
static void zclSmartplug_ProcessZDOMsgs( zdoIncomingMsg_t *pMsg )
{
  zclEZMode_ActionData_t data;
  ZDO_MatchDescRsp_t *pMatchDescRsp;

  // Let EZ-Mode know of the Simple Descriptor Response
  if ( pMsg->clusterID == Match_Desc_rsp )
  {
    pMatchDescRsp = ZDO_ParseEPListRsp( pMsg );
    data.pMatchDescRsp = pMatchDescRsp;
    zcl_EZModeAction( EZMODE_ACTION_MATCH_DESC_RSP, &data );
    osal_mem_free( pMatchDescRsp );
    
    binding_success_LED = TRUE;
  }
}

     and  it could not be working ! it could not set a breakpoint in this function.

but when i change the  end device EZMODE data that  initiator setting as TRUE

this function was working . and LED will be turned on after binding success.
