Azure IoT hub client

Have you ever felt the need to test an IoT Hub connection? This is a simple console program allows you to send messages to an Azure IoT Hub. It is based on Microsoft.Azure.Devices.Client.

How do I get it?

You can download the tool from the Releases or download the source code and run dotnet build.

How do I use it?

1. Create a IoT Device and get it's connection string

2. Run the IotHubClient.exe with the devices connection string

   .\IotHubClient.exe "HostName=test-hub.azure-devices.net;DeviceId=TestDevice;SharedAccessKey=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA="

That's it. The program will run and send one message every minute (by default) or whenever you hit the space key.

It will send UTF8 encoded JSON messages like

{
    "MessageNo": 1,
