OTA过程分析

1：硬件初始化

2：初始化设备：路由，Z3设备

3：初始化发送回调函数：messageSentCallbacks

4：端点初始化

  端点号，PROFILEID,设备ID，设备版本，

  簇的初始化：端点包含的簇的属性，服务端仍是客户端，簇的初始化函数，属性属性变化函数

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

初始化函数只是初始化，如今并无调用簇的初始化函数，属性只是分配空间，尚未赋值

5：emberAfInit

   初始化属性值，而后把NV里的值装到属性里

   初始化插件

　#define EMBER_AF_GENERATED_PLUGIN_INIT_FUNCTION_CALLS \

emberAfPluginBulbPwmDriverInitCallback(); \

emberAfPluginCountersInitCallback(); \

emberAfPluginEepromInitCallback(); \

emberAfPluginElectricalMeasurementServerInitCallback(); \

emberAfPluginLedDimPwmInitCallback(); \

emberAfPluginPowerMeterCs5463InitCallback(); \

emberAfPluginReportingInitCallback(); \

 

     调用簇的初始化函数

网络初始化

 EM_AF_NETWORK_INIT();

 

//========

网络状态起来的时候调用。

#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); \

recordUpgradeStatus(BOOTLOAD_STATE_DELAY);  //

emberAfScheduleClientTickExtended(myEndpoint,

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

7：有几个属性必须得设定
