OTA過程分析

1：硬件初始化

2：初始化設備：路由，Z3設備

3：初始化發送回調函數：messageSentCallbacks

4：端點初始化

  端點號，PROFILEID,設備ID，設備版本，

  簇的初始化：端點包含的簇的屬性，服務端仍是客戶端，簇的初始化函數，屬性屬性變化函數

EmberAfGenericClusterFunction emberAfFuncArrayOtaBootloadClusterClient[] = { (EmberAfGenericClusterFunction)emberAfOtaBootloadClusterClientInitCallback,(EmberAfGenericClusterFunction)emberAfOtaBootloadClusterClientDefaultResponseCallback};

初始化函數只是初始化，如今並無調用簇的初始化函數，屬性只是分配空間，尚未賦值

5：emberAfInit

   初始化屬性值，而後把NV裏的值裝到屬性裏

   初始化插件

　#define EMBER_AF_GENERATED_PLUGIN_INIT_FUNCTION_CALLS \

emberAfPluginBulbPwmDriverInitCallback(); \

emberAfPluginCountersInitCallback(); \

emberAfPluginEepromInitCallback(); \

emberAfPluginElectricalMeasurementServerInitCallback(); \

emberAfPluginLedDimPwmInitCallback(); \

emberAfPluginPowerMeterCs5463InitCallback(); \

emberAfPluginReportingInitCallback(); \

 

     調用簇的初始化函數

網絡初始化

 EM_AF_NETWORK_INIT();

 

//========

網絡狀態起來的時候調用。

#define\

void emberAfPluginElectricalMeasurementServerStackStatusCallback(EmberStatus status); \
void emberAfPluginManufacturingLibraryOtaStackStatusCallback(EmberStatus status); \
void emberAfPluginMeteringServerStackStatusCallback(EmberStatus status); \
void emberAfPluginNetworkSteeringStackStatusCallback(EmberStatus status); \
void emberAfPluginOtaClientStackStatusCallback(EmberStatus status); \
void emberAfPluginReportingStackStatusCallback(EmberStatus status); \

void emberAfPluginOtaClientStackStatusCallback(EmberStatus status)
{

typedef uint8_t BootloadState;

 

//升級狀態，對應簇的屬性ID:0x0006

};

recordUpgradeStatus(BOOTLOAD_STATE_DELAY);  //

emberAfScheduleClientTickExtended(myEndpoint,
ZCL_OTA_BOOTLOAD_CLUSTER_ID,
randomDelaySeconds * MILLISECOND_TICKS_PER_SECOND,
pollControl,
sleepControl);

{ 0x1, 0x19, true, EMBER_AF_LONG_POLL, EMBER_AF_OK_TO_SLEEP, &emberAfOtaBootloadClusterClientTickCallbackControl1}, \
}

7：有幾個屬性必須得設定
