ZigBee协议栈初始化网络启动流程

ZigBee协议栈初始化网络启动流程

ZigBee的基本流程：由协调器的组网（创建PAN ID），终端设备和路由设备发现网络以及加入网络。

基本流程：main()->osal_init_system()->osalInitTasks()->ZDApp_Init()，进协议栈初始化函数ZDApp_Init()。

进入程序入口main()。

中

C++ Code

int main( void )

{

WatchDogEnable( WDTIMX );

#endif

osal_start_system(); }

ZDO_Init();

afRegister( (endPointDesc_t

*)&ZDApp_epDesc );

#if defined( ZDO_USERDESC_RESPONSE )

ZDApp_InitUserDesc();

#endif

zgInitItems( FALSE );

}

ZDConfig_InitDescriptors();

zgWriteStartupOptions( ZG_STARTUP_SET,

ZCD_STARTOPT_DEFAULT_NETWORK_STATE );

}

}

else if ( startMode == MODE_RESUME )

#endif

}

开启网络事件

C++ Code

void ZDO_NetworkFormationConfirmCB( ZStatus_t Status )

{

nwkStatus = (byte)Status;

if ( Status == ZSUCCESS )

{

// LED on shows Coordinator started

HalLedSet ( HAL_LED_3,

HAL_LED_MODE_ON );

// LED off forgets

#if defined ( ZBIT )

SIM_SetColor(0xd0ffd0);

#endif

if ( devState == DEV_HOLD )

{

// Began with HOLD_AUTO_START

devState = DEV_COORD_STARTING;

}

}

#if defined(BLINK_LEDS)

else

HalLedSet ( HAL_LED_3, HAL_LED_MODE_FLASH ); // Flash LED to show failure

#endif

osal_set_event( ZDAppTaskID,

ZDO_NETWORK_START );
