OTA网关子设备固件升级

网关子设备固件升级简介

由于子设备无法直接和云端建立连接，网关设备延用设备OTA升级方式对子设备进行固件升级，支持网关子设备单台升级和批量升级。

如果您还不清楚设备固件升级的使用，请参考 固件升级 文档

运行示例程序体验检查OTA网关子设备固件升级功能

请先按照 网关功能 的步骤，填写好网关设备和子设备对应的设备信息，将网关设备 连接MQTT 进行认证接入。

运行示例程序，在基础功能模块上，点击上报子设备版本按钮，将上报子设备固件版本号检查是否有固件更新。示例代码如下：

mMQTTSample.initOTA();  // 初始化 ota 服务，开始监听平台的推送
mMQTTSample.reportSubDevVersion("0.0");

以下是网关设备及子设备成功订阅 OTA 升级的 Topic 主题 和 子设备上报当前版本号 的logcat日志，示例中的版本号version传入的值为0.0。

I/com.tencent.iot.hub.device.java.core.mqtt.TXMqttConnection: Starting subscribe topic: $ota/update/AP9ZLEVFKT/gateway1
I/com.tencent.iot.hub.device.java.core.mqtt.TXMqttConnection: Starting subscribe topic: $ota/update/9RW4A8OOFK/door1
D/TXMQTT: onSubscribeCompleted, status[OK], topics[[$ota/update/AP9ZLEVFKT/gateway1]], userContext[], errMsg[subscribe success]
D/TXMQTT: onSubscribeCompleted, status[OK], topics[[$ota/update/9RW4A8OOFK/door1]], userContext[], errMsg[subscribe success]
I/com.tencent.iot.hub.device.java.core.mqtt.TXMqttConnection: Starting publish topic: $ota/report/9RW4A8OOFK/door1 Message: {"type":"report_version","report":{"version":"0.0"}}
D/TXMQTT: onPublishCompleted, status[OK], topics[[$ota/report/9RW4A8OOFK/door1]],  userContext[], errMsg[publish success]

当在控制台中触发子设备固件升级操作后，再次点击上报子设备版本按钮，设备端会通过订阅的子设备 OTA 升级的 Topic $ota/update/${productID}/${deviceName} 收到固件升级的消息

以上日志为 子设备收到固件升级的消息 ，下载并显示下载进度，下载新版本固件成功后，上报最新的版本号，此时示例中上报的最新版本号version为0.0.1。
