层（应用层）进行启动进行确认，至此协调器的整个启动过程完成。其中详细代码如下：
? ZDO任务初始化：
void ZDApp_Init( byte task_id ) {
uint8 capabilities;
// Save the task ID
ZDAppTaskID = task_id;
// Initialize the ZDO global device short address storage
ZDAppNwkAddr.addrMode = Addr16Bit;//地址模式为16bit短地址
ZDAppNwkAddr.addr.shortAddr = INVALID_NODE_ADDR;//短地址=0xFFFE (void)NLME_GetExtAddr(); // Load the saveExtAddr pointer，API函数-》得到64bit IEEE地址
// Check for manual \
ZDAppCheckForHoldKey();//用户可以通过S5手动制止该设备自动启动
// Initialize ZDO items and setup the device - type of device to create.
ZDO_Init();
// Register the endpoint description with the AF
// This task doesn't have a Simple description, but we still need // to register the endpoint.
afRegister( (endPointDesc_t *)&ZDApp_epDesc );//为设备注册端点0描述符
#if defined( ZDO_USERDESC_RESPONSE ) ZDApp_InitUserDesc();
#endif // ZDO_USERDESC_RESPONSE
// set broadcast address mask to support broadcast filtering
NLME_GetRequest(nwkCapabilityInfo, 0, &capabilities);//获得网络信息库的属性值-网络容量
NLME_SetBroadcastFilter( capabilities );//根据网络容量设置掩码，用于处理有效的广播地址
// Start the device?
if ( devState != DEV_HOLD )//根据上面函数ZDAppCheckForHoldKey()决定 {
ZDOInitDevice( 0 ); } else {
// Blink LED to indicate HOLD_START HalLedBlink ( HAL_LED_4, 0, 50, 500 ); }
ZDApp_RegisterCBs(); } /* ZDO_Init() */

? ZDO启动设备：
uint8 ZDOInitDevice( uint16 startDelay ) {
uint8 networkStateNV = ZDO_INITDEV_NEW_NETWORK_STATE;//0x01,初始化该设备新的网络状态
uint16 extendedDelay = 0;
devState = DEV_INIT; // Remove the Hold state
//not connected to anything，无连接
// Initialize leave control logic ZDApp_LeaveCtrlInit();
// Check leave control reset settings
ZDApp_LeaveCtrlStartup( &devState, &startDelay );
// Leave may make the hold state come back if ( devState == DEV_HOLD )
return ( ZDO_INITDEV_LEAVE_NOT_STARTED ); // Don't join - (one time).
#if defined ( NV_RESTORE )//project->Options->C/C++ complier->defined symbols->xNV_RESTORE,此项预编译为无效
// Get Keypad directly to see if a reset nv is needed.
// Hold down the SW_BYPASS_NV key (defined in OnBoard.h) // while booting to skip past NV Restore. if ( HalKeyRead() == SW_BYPASS_NV )

// Determine if NV should be restored
networkStateNV = ZDApp_ReadNetworkRestoreState(); }
if ( networkStateNV == ZDO_INITDEV_RESTORED_NETWORK_STATE ) {
networkStateNV = ZDApp_RestoreNetworkState(); } else {
// Wipe out the network state in NV NLME_InitNV();
NLME_SetDefaultNV(); } #endif
17
if ( networkStateNV == ZDO_INITDEV_NEW_NETWORK_STATE ) {
ZDAppDetermineDeviceType();//确定该设备的类型
// Only delay if joining network - not restoring network state
extendedDelay = (uint16)((NWK_START_DELAY + startDelay)
+ (osal_rand() & EXTENDED_JOINING_RANDOM_MASK));//加入网络的时延
}
// Initialize device security
ZDApp_SecInit( networkStateNV );//初始化设备的安全属性
// Trigger the network start
ZDApp_NetworkInit( extendedDelay );//开始形成网络。任务：ZDAppTaskID, 事件：ZDO_NETWORK_INIT
return ( networkStateNV ); }
? ZDO初始化网络：
void ZDApp_NetworkInit( uint16 delay ) {
if ( delay ) {
// Wait awhile before starting the device
osal_start_timerEx( ZDAppTaskID, ZDO_NETWORK_INIT, delay ); } else {
osal_set_event( ZDAppTaskID, ZDO_NETWORK_INIT );//ZDO_NETWORK_INIT事件处理函数查看ZDApp_event_loop()
} } ④ 处理ZDO网络初始化事件
UINT16 ZDApp_event_loop( byte task_id, UINT16 events ) {
……
if ( events & ZDO_NETWORK_INIT )//网络初始化事件处理 {
// Initialize apps and start the network devState = DEV_INIT;
ZDO_StartDevice( (uint8)ZDO_Config_Node_Descriptor.LogicalType, devStartMode, DEFAULT_BEACON_ORDER,

DEFAULT_SUPERFRAME_ORDER );//设备逻辑类型，启动模式，信标时间，超帧长度
//HalLedSet (HAL_LED_1, HAL_LED_MODE_ON);
// Return unprocessed events
return (events ^ ZDO_NETWORK_INIT); } …… } ⑤ ZDO启动设备
void ZDO_StartDevice( byte logicalType, devStartModes_t startMode, byte beaconOrder, byte superframeOrder )
{
……
#if defined(ZDO_COORDINATOR)
if ( logicalType == NODETYPE_COORDINATOR ) {
if ( startMode == MODE_HARD ) {
devState = DEV_COORD_STARTING;
ret = NLME_NetworkFormationRequest( zgConfigPANID, zgDefaultChannelList, zgDefaultStartingScanDuration, beaconOrder,
superframeOrder, false );//0xFFFF,0x00000800,5,0,0,false
} …… } ⑥ 建立网络确认
void ZDO_NetworkFormationConfirmCB( ZStatus_t Status ) {
#if defined(ZDO_COORDINATOR)
……
osal_set_event( ZDAppTaskID, ZDO_NETWORK_START ); #endif //ZDO_COORDINATOR }
⑦ 处理ZDO网络启动事件
