Lets create a C# simulator which will send device-to-cloud message using MQTT protocol:
- Create a device simulator to send a message to IoT Hub:
deviceClient = DeviceClient.CreateFromConnectionString("HostName=IoTHubCookBook.azure-devices.net;DeviceId=myFirstDevice;SharedAccessKey=XXXXXXXXXXXXX", TransportType.Mqtt);new DeviceSimulator().SendDeviceToCloudMessagesAsync(deviceClient, "myFirstDevice");
- Send IoT Hub messages using MQTT:
public async void SendDeviceToCloudMessagesAsync(DeviceClient deviceClient1, string deviceId) public async void SendDeviceToCloudMessagesAsync(DeviceClient deviceClient1, string deviceId) { double avgWindSpeed = 10; // m/s Random rand = new Random(); double currentWindSpeed = 0; int i = 0; ...
