将Eclipse Kura与Micorosoft Azure IoT Hub连接后出现MQTT问题

标签： eclipse azure iot kura

我使用Eclipse Kura创建了与Microsoft Azure Cloud的连接：以下是Kura UI的屏幕截图： Screen Shot of Kura

当我运行Kura服务器时，它会向IOT Hub发送一些消息（一次性10-15）。即使没有在Kura上部署包或捆绑包，消息号也会每隔几秒钟增加一次。

记录器中还有一个 EndOfFileException 。以下是在Kura中生成的日志：

感谢任何帮助。 另外，由于我是Kura的新手，如果有人可以建议我一步一步的DataService教程，那就太棒了。

我们（Azure IoT SDK团队）刚刚与Kura开发团队合作启动了一个正在进行的工作，以便为Azure IoT Hub提供Eclipse Kura连接器。您可以在此处查看此工作：https://github.com/andrew-buckley/kura/tree/AzureIntegration
