Question

我正在尝试从运行Raspbian OS的BananaPi M3向Azure IoT中心（AIH）服务器发送一些数据。为此，我为AIH构建了Python 2.7库，并获得了名为iothub_client.so的有效库。为了测试lib是否正常，我只是尝试进行一个简单的导入，例如：from iothub_client import *并且它有效。
因此，在此之后，我按照Math.max所述设置连接字符串，并从here运行脚本。
这是应用程序的输出：

有没有人知道为什么我会收到所有TIMEOUT消息？
谢谢

尝试将协议更改为HTTP 例如：

PROTOCOL = IoTHubTransportProvider.HTTP

在Python2.7中发送数据时，Azure IoT中心发布者TIMEOUT
