判断zigbee设备的网络状态

2019-07-20 16:16发布

判断网络状态：
一、
1、extern devStates_t devState;（在ZDApp.h中声明）
typedef enum
{
  DEV_HOLD,             // Initialized - not started automatically
  DEV_INIT,             // Initialized - not connected to anything
  DEV_NWK_DISC,          // Discovering PAN's to join
  DEV_NWK_JOINING,       // Joining a PAN
  DEV_NWK_REJOIN,       // ReJoining a PAN, only for end devices
  DEV_END_DEVICE_UNAUTH,  // Joined but not yet authenticated by trust center
  DEV_END_DEVICE,       // Started as device after authentication
  DEV_ROUTER,          // Device joined, authenticated and is a router
  DEV_COORD_STARTING,    // Started as Zigbee Coordinator
  DEV_ZB_COORD,          // Started as Zigbee Coordinator
  DEV_NWK_ORPHAN       // Device has lost information about its parent..
} devStates_t;
2、HAL_LED_3灯的状态。
亮表示设备成为Coo（ZDO_NetworkFormationConfirmCB函数）或者Route（ZDO_StartRouterConfirmCB函数）成功、加网成功（ZDO_JoinConfirmCB函数），
闪烁表示失败。在ZDApp.c文件中设值。

二、
1、在主task中注册ZDO_STATE_CHANGE消息的事件函数。
2、在消息事件相应函数中可以获取新状态，用于判断设备状态。
uint16 ***_event_loop(()
{
  if ( events & SYS_EVENT_MSG )
  {
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( ***_TaskID );
while ( MSGpkt )
{
   switch ( MSGpkt->hdr.event )
   {
case ZDO_STATE_CHANGE:
      ***_NwkState = (devStates_t)(MSGpkt->hdr.status);
      break;

      default:
      break;
   }

   // Release the memory
   osal_msg_deallocate( (uint8 *)MSGpkt );

   // Next
   MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( ***_TaskID );
}

// Return unprocessed events
return (events ^ SYS_EVENT_MSG);
  }
}
注意：只有EndDevice设备才能判断是否是孤儿节点，router设备是不能的
