Zigbee網(wǎng)絡(luò)設(shè)備啟動(dòng)-基本問題說明

1、記錄幾個(gè)問題：1、有關(guān)設(shè)備的啟動(dòng)模式選項(xiàng):（有待完善）：非自動(dòng)啟動(dòng)模式HOLD_AUTO_START：HOLD_AUTO_STARTisacompileoptionthatwillsurpressZDAppfromstartingthedeviceandwaitfortheapplicationtostartthedevice.不通過ZDApp（具體講是ZDOInitDevice（）而是等待應(yīng)用程序來開啟設(shè)備并初始化建立/加入網(wǎng)絡(luò).軟啟動(dòng)模式SOFT_START：SOFT_STARTisacompileoptionthatallowsthedevicetostartasacoordinator

2、ifoneisntfound.Otherwise,thedevicewillstartasarouter.如果沒有協(xié)調(diào)器則作為協(xié)調(diào)器啟動(dòng)，有則作為路由器啟動(dòng).自動(dòng)啟動(dòng)模式：個(gè)人認(rèn)為就是自動(dòng)通過ZDApp（具體講是ZDOInitDevice（）來開啟設(shè)備并初始化建立/加入網(wǎng)絡(luò)，設(shè)備的邏輯類型由所攜帶的配置文件來決定.2、三種邏輯類型節(jié)點(diǎn)的配置文件協(xié)調(diào)器：f8wCoord.cfg配置文件中同時(shí)編譯了路由功能RTR_NWK和協(xié)調(diào)器功能ZDO_COORDINATOR/*CommonToAllApplications*/-DCPU32MHZ/CC2430sRunat32MHz-DFORCE_MAC_NE

5、=const_code-DGENERIC=_generic/Ptrdeclaration終端：f8wEdev.cfg配置文件中沒有編譯這兩個(gè)功能./*CommonToAllApplications*/-DCPU32MHZ/CC2430sRunat32MHz-DFORCE_MAC_NEAR/MACcodeinNEAR-DROOT=_near_func/MAC/ZMACcodeinNEAR/*OptionalSettings*/-DMAC_OPT_FFD=0/ZigBeeRFD-DBLINK_LEDS/LEDBlinkFunctions/*Compilerkeywords*/-DCONST=con

6、st_code-DGENERIC=_generic/Ptrdeclaration協(xié)調(diào)器的配置文件只比路由器配置文件多編譯了個(gè)-DZDO_COORDINATOR/CoordinatorFunctions如果同時(shí)編譯非自動(dòng)啟動(dòng)模式HOLD_AUTO_START和軟啟動(dòng)模式SOFT_START,設(shè)備可以通過應(yīng)用程序來選擇成為路由器或協(xié)調(diào)器.當(dāng)然這個(gè)設(shè)備所帶的配置文件應(yīng)為f8wCoord.cfg.對(duì)于設(shè)備攜帶的是何種配置文件,可以打開project-options-c/c+compiler-extraOptions選項(xiàng)查看.比如SampleApp中的DemoEB，同時(shí)編譯了SOFT_START和HOL

7、D_AUTO_START,貌似下載進(jìn)去后通過外部跳線來選擇是當(dāng)協(xié)調(diào)器還是路由器，不過這部分程序已經(jīng)被注銷了.當(dāng)然的，DemoEB所帶的配置文件應(yīng)該是同時(shí)編譯了路由功能和協(xié)調(diào)器功能的f8wCoord.cfg,即編譯了RTR_NWK和ZDO_COORDINATOR.再比女口SimpleApp中兩個(gè)實(shí)驗(yàn)中的燈與開關(guān)實(shí)驗(yàn).開關(guān)設(shè)備SimpleSwitchEB無論按K1還是K2都是作為終端設(shè)備的，其預(yù)編譯選項(xiàng)只有HOLD_AUTO_START而沒有SOFT_START，配置文件為f8wEndev.cfg,沒有協(xié)調(diào)器和路由功能;而燈設(shè)備SimpleControllerEB按鍵K1則作為協(xié)調(diào)器，按K2則作為

8、路由器，其預(yù)編譯選項(xiàng)同時(shí)編譯了SOFT_START和HOLD_AUTO_START，配置文件為f8wCoordcfg,即編譯了RTR_NWK和ZDO_COORDINATOR.SimpleApp中傳感器實(shí)驗(yàn)也一樣，只能作為終端設(shè)備的SimpleSensorEB預(yù)編譯了HOLD_AUTO_START,配置文件為f8wEndev.cfg;而SimpleCollectorEB按K1作為協(xié)調(diào)器按K2作為路由器，預(yù)編譯了SOFT_START和HOLD_AUTO_START,配置文件f8wCoord.cfg.可以通過project-options-c/c+compiler-extraOptions選項(xiàng)查看，

13、ForHoldKey();(Checkformanual(手工的)HoldAutoStart).來看下這個(gè)函數(shù)：voidZDAppCheckForHoldKey(void)#if(definedHAL_KEY)&(HAL_KEY=TRUE)/直接通過讀取按鍵來判斷是否需要采用HOLD_AUTO_START模式,如果發(fā)現(xiàn)SW_1處于按下(普通按鍵?)/向上(Joystickup)狀態(tài),則設(shè)置devState為DEV_HOLD;/GetKeypaddirectlytoseeifaHOLD_STARTisneeded./HolddowntheSW_BYPASS_STARTkey(seeOnBoard

14、.h)/whilebootingtoavoidstartingupthedevice.if(HalKeyRead()=SW_BYPASS_START)/HAL_KEY_SW_1/ChangethedevicestatetoHOLDonstartupdevState=DEV_HOLD;#endif/HAL_KEY可以看到如果手工使HAL_KEY_SW_1置位狀態(tài)，則會(huì)設(shè)置devState=DEV_HOLD.這里HAL_KEY的初始化見hal_board_cfg.h：#ifndefHAL_KEY#defineHAL_KEYTRUE#endif而對(duì)SW_BYPASS_START的初始化見OnBoar

15、d.h：/TheseKeydefinitionsareuniquetothisdevelopmentsystem./Theyareusedtobypassfunctionswhenstartingupthedevice./這些鍵的定義僅適用于本應(yīng)用例子，可以在設(shè)備啟動(dòng)時(shí)避開一些功能：/避開網(wǎng)絡(luò)層的NV存儲(chǔ)和避開網(wǎng)絡(luò)初始化#defineSW_BYPASS_NVHAL_KEY_SW_5/BypassNetworklayerNVrestore#defineSW_BYPASS_STARTHAL_KEY_SW_1/BypassNetworkinitialization因此避開網(wǎng)絡(luò)層NV存儲(chǔ)也可以通過手工

16、方式來完成.(2)、預(yù)編譯方式：project-options-c/c+compiler-preprocessor-definedsymbols下編譯選項(xiàng)：HOLD_AUTO_STARTSimpleApp例子里四種節(jié)點(diǎn)都預(yù)編譯了HOLD_AUTO_START:非自動(dòng)啟動(dòng)模式在ZDApp.c中：#ifdefined(HOLD_AUTO_START)devStates_tdevState=DEV_HOLD;#elsedevStates_tdevState=DEV_INIT;#endif把devState初始化為DEV_HOLD.以上兩種方式最終都會(huì)設(shè)置devState=DEV_HOLD/Initi

17、alized-notstartedautomatically4、devStartMode和devState的初始化,ZDApp.c中：devStartMode:#ifdefined(ZDO_COORDINATOR)&!defined(SOFT_START)/SetthedefaulttocoodinatordevStartModes_tdevStartMode=MODE_HARD;#elsedevStartModes_tdevStartMode=MODE_JOIN;/Assumejoining/devStartModes_tdevStartMode=MODE_RESUME;/ifalready

18、directlyjoined/toparent.SettomakethedevicedoanOrphanscan.#endif編譯了ZDO_COORDINATOR并且沒有編譯SOFT_START,則初始化devStartMode=MODE_HARD;其他情況初始化devStartMode=MODE_RESUME;比如SampleApp三種邏輯類型節(jié)點(diǎn).devState:#ifdefined(HOLD_AUTO_START)devStates_tdevState=DEV_HOLD;/Initialized-notstartedautomatically#elsedevStates_tdevSta

19、te=DEV_INIT;/Initialized-notconnectedtoanything#endif預(yù)編譯了HOLD_AUTO_START,則devState=DEV_HOLD;否則devState=DEV_INIT;5、存儲(chǔ)設(shè)備邏輯類型的NV條目ZCD_NV_LOGICAL_TYPE:在ZGlobals.c下的NV條目表ZGlobalItemTable有這么一個(gè)條目：staticCONSTzgItem_tzgItemTable=#ifdefined(NV_INIT)ZCD_NV_LOGICAL_TYPE,sizeof(zgDeviceLogicalType),&zgDeviceLogi

20、calType,zgItem_t結(jié)構(gòu)體如下:typedefstructzgItemuint16id;uint16len;void*buf;zgItem_t;ZDO全局變量zgDeviceLogicalType被初始化為uint8zgDeviceLogicalType=DEVICE_LOGICAL_TYPE;因此這里全局變量zgDeviceLogicalType的值為NV條目ZCD_NV_LOGICAL_TYPE的值，buf指向zgDeviceLogicalType.如果在應(yīng)用程序中改變了設(shè)備邏輯類型并寫入NV條目ZCD_NV_LOGICAL_TYPE中,這時(shí)即全局變量zgDeviceLogic

21、alType的值改變了(卡在這步上近兩天，因?yàn)檎也恢淖兊倪壿嫚顟B(tài)與設(shè)備開啟時(shí)選擇的邏輯狀態(tài)之間的關(guān)系).(2)NV條目ZCD_NV_LOGICAL_TYPE的值有哪些?/DeviceLogicalType/NV條目ZCD_NV_LOGICAL_TYPE的值包括:(即zgDeviceLogicalType的值)/ValuesforZCD_NV_LOGICAL_TYPE(zgDeviceLogicalType)#defineZG_DEVICETYPE_COORDINATOR0 x00#defineZG_DEVICETYPE_ROUTER0 x01#defineZG_DEVICETYPE_ENDD

22、EVICE0 x02#defineZG_DEVICETYPE_SOFT0 x03對(duì)于DEVICE_LOGICAL_TYPE的值各邏輯類型設(shè)備初始化如下：/DeviceLogicalType/zgDeviceLogicalType=DEVICE_LOGICAL_TYPE#ifdefined(SOFT_START)#defineDEVICE_LOGICAL_TYPEZG_DEVICETYPE_SOFT/可選擇類型#elifdefined(ZDO_COORDINATOR)#defineDEVICE_LOGICAL_TYPEZG_DEVICETYPE_COORDINATOR/協(xié)調(diào)器#elifdefin

23、ed(RTR_NWK)#defineDEVICE_LOGICAL_TYPEZG_DEVICETYPE_ROUTER/路由器#else#defineDEVICE_LOGICAL_TYPEZG_DEVICETYPE_ENDDEVICE/終端#endif如果編譯了SOFT_START，則初始化DEVICE_LOGICAL_TYPE=ZG_DEVICETYPE_SOFT，即zgDeviceLogicalType=ZG_DEVICETYPE_SOFT;如果沒有編譯SOFT_START但編譯了ZDO_COORDINATOR,則初始DEVICE_LOGICAL_TYPE=ZG_DEVICETYPE_COOR

24、DINATOR,即zgDeviceLogicalType=ZG_DEVICETYPE_COORDINATOR;路由器和終端類似.6、啟動(dòng)設(shè)備都要通過ZDApp_event_loop()函數(shù)調(diào)用ZDO_StartDevice()對(duì)ZDO_NETWORK_INIT事件的處理:ZDO_StartDevice(uint8)ZDO_Config_Node_Descriptor.LogicalType，devStartMode，DEFAULT_BEACON_ORDER，DEFAULT_SUPERFRAME_ORDER);這里對(duì)于設(shè)備邏輯類型的傳遞參數(shù)ZDO_Config_Node_Descriptor.L

25、ogicalType，ZDConfig.c中初始化是這樣的：NodeDescriptorFormat_tZDO_Config_Node_Descriptor=#ifdefined(ZDO_COORDINATOR)&!defined(SOFT_START)NODETYPE_COORDINATOR，/協(xié)調(diào)器#elifdefined(RTR_NWK)NODETYPE_ROUTER，/路由器#elseNODETYPE_DEVICE，/終端設(shè)備/LogicalType#endif如果編譯了ZDO_COORDINATOR且沒有編譯SOFT_START,則ZDO_Config_Node_Descriptor

26、.LogicalType的值為NODETYPE_COORDINATOR;如果沒有編譯ZDO_COORDINATOR或者編譯了SOFT_START,且編譯了了RTR_NWK,則ZDO_Config_Node_Descriptor.LogicalType的值為NODETYPE_ROUTER(比如simpleApp中燈節(jié)點(diǎn)和中心收集節(jié)點(diǎn)就是這種情況，因此它倆的ZDO_Config_Node_Descriptor.LogicalType被初始化為NODETYPE_ROUTER,當(dāng)然當(dāng)通過外部按鍵選擇設(shè)備邏輯類型為協(xié)調(diào)器時(shí)，會(huì)通過內(nèi)部程序把這個(gè)值改為NODETYPE_COORDINATOR,這點(diǎn)后面再作

27、記錄);剩下情況為NODETYPE_DEVICE.7、simpleApp中的按鍵完成兩個(gè)功能：設(shè)置設(shè)備的邏輯類型(ZC/ZR/ED)和設(shè)置設(shè)備的啟動(dòng)方式(ZCD_STARTOPT_AUTO_START)，然后寫入相應(yīng)的NV條目ZCD_NV_LOGICAL_TYPE和ZCD_NV_STARTUP_OPTION.ZDApp_Init()是先于應(yīng)用任務(wù)如SampleApp_Init()初始化的.ZCD_NV_STARTUP_OPTION值包括:/Thesearebitweighted-youcanORthesetogether./Settingoneofthesebitswillsettheiras

29、T_DEFAULT_NETWORK_STATE/清除狀態(tài)=默認(rèn)網(wǎng)絡(luò)狀態(tài)ZCD_NV_LOGICAL_TYPE值參見4.8、網(wǎng)絡(luò)狀態(tài)的類型：/設(shè)備的網(wǎng)絡(luò)狀態(tài)為恢復(fù)的網(wǎng)絡(luò)狀態(tài)#defineZDO_INITDEV_RESTORED_NETWORK_STATE0 x00網(wǎng)絡(luò)狀態(tài)初始化,即設(shè)備的網(wǎng)絡(luò)狀態(tài)為新的網(wǎng)絡(luò)狀態(tài).可能意味著ZCD_NV_STARTUP_OPTION不能恢復(fù),或沒有任何網(wǎng)絡(luò)狀態(tài)恢復(fù)#defineZDO_INITDEV_NEW_NETWORK_STATE0 x01復(fù)位前，網(wǎng)絡(luò)重返選項(xiàng)為TRUE,因此該設(shè)備在網(wǎng)絡(luò)中沒有啟動(dòng)(僅一次)，下次調(diào)用該函數(shù)將啟動(dòng).#defineZDO_INITD

42、mpleApp例子，每次設(shè)備重啟配置狀態(tài)都為默認(rèn)值.而如果用戶改變了ZCD_NV_STARTUP_OPTION的值，比如SimpleApp中:zb_ReadConfiguration(ZCD_NV_STARTUP_OPTION,sizeof(uint8),&startOptions);startOptions=ZCD_STARTOPT_AUTO_START;zb_WriteConfiguration(ZCD_NV_STARTUP_OPTION,sizeof(uint8),&startOptions);zb_SystemReset();每次按鍵后都會(huì)先把設(shè)備邏輯狀態(tài)寫入NV中(準(zhǔn)備下次啟動(dòng)設(shè)備時(shí)

44、RTOPT_DEFAULT_CONFIG_STATE標(biāo)志位不為1,setDefaUt保持FALSE,因而進(jìn)入NV配置狀態(tài)條目初始化zgItemint()時(shí)，執(zhí)行的是：else條目存在,setDefault=FALSE,讀取原先存儲(chǔ)的值/TheitemexistsinNVmemory,readitfromNVmemorystatus=osal_nv_read(id,0,len,buf);這樣把上次存儲(chǔ)在NV條目ZCD_NV_LOGICAL_TYPE中的設(shè)備邏輯類型值讀出作為此次NV條目ZCD_NV_LOGICAL_TYPE的值.問題是，還未確定開啟選項(xiàng)ZCD_NV_STARTUP_OPTION的
