协调器自启动模式.doc

使用的协议栈版本信息: ZigBee2006\ZStack-1.4.3-1.2.1Zigbee网络设备启动流程—协调器(自启动模式)—以SampleApp的协调器为例.1、协调器预编译信息通过project-options-c/c++compiler-extraOptions可以看到协调器所带的配置文件为：-f $PROJ_DIR$\..\..\..\Tools\CC2430DB\f8wCoord.cfg-f $PROJ_DIR$\..\..\..\Tools\CC2430DB\f8wConfig.cfg即编译了ZDO_COORDINATOR和RTR_NWK.通过project-options-c/c++compiler-Preprocessor-Defined symbols可以看到协调器预编译包含了：CC2430EB; ZTOOL_P1; MT_TASK; LCD_SUPPORTED=DEBUG; MANAGED_SCAN没有编译HOLD_AUTO_START和SOFT_START.2、具体流程main()-osal_init_system()-osalInitTasks()-ZDApp_Init() 进入ZDApp_Init()函数:**************************************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;??ZDAppNwkAddr.addr.shortAddr = INVALID_NODE_ADDR;?//0xFFFE??(void)NLME_GetExtAddr();?// Load the saveExtAddr pointer.??// Check for manualHold Auto Start??//检测到有手工设置SW_1则会设置devState = DEV_HOLD,从而避开网络初始化??ZDAppCheckForHoldKey();// Initialize ZDO items and setup the device - type of device to create.??ZDO_Init();?//通过判断预编译来开启一些函数功能??// Register the endpoint description with the AF??// This task doesnt have a Simple description, but we still need??// to register the endpoint.??afRegister( (endPointDesc_t *)ZDApp_epDesc );#if defined( ZDO_USERDESC_RESPONSE )??ZDApp_InitUserDesc();#endif?// ZDO_USERDESC_RESPONSE??// set broadcast address mask to support broadcast filtering??NLME_GetRequest(nwkCapabilityInfo, 0, capabilities);??NLME_SetBroadcastFilter( capabilities );??// Start the device???if ( devState != DEV_HOLD )??{????ZDOInitDevice( 0 );??}????else??{????// Blink LED to indicate HOLD_START????HalLedBlink ( HAL_LED_4, 0, 50, 500 );??}??ZDApp_RegisterCBs();} **************************************协调器没有编译HOLD_AUTO_START,也没有手工设置SW_1,初始化devState = DEV_INIT(参见基本问题说明3).因此直接在ZDApp_Init()中进入ZDOInitDevice( 0 )开启设备.**************************************uint8 ZDOInitDevice( uint16 s
