Hyper Text Transfer Protocol Secure (HTTPS)

HTTPS is one of the application protocols used for communicating between device-to-cloud and cloud-to-device. When you are using HTTP, devices poll IoT Hub for messages.

The HTTP protocol works for the command/response IoT system between the IoT device and the cloud application.

How to do it...

We will create a simulator and ingest data to IoT Hub:

1. Create a device simulator to send a message to the IoT:

deviceClient = DeviceClient.CreateFromConnectionString("HostName=IoTHubCookBook.azure-devices.net;DeviceId=myFirstDevice;SharedAccessKey=XXXXXXXXXXXXX", TransportType.Http1);

new DeviceSimulator().SendDeviceToCloudMessagesAsync(deviceClient, "myFirstDevice");

2. Send IoT Hub messages using HTTP:

public async void SendDeviceToCloudMessagesAsync(DeviceClient deviceClient1, string deviceId) public async void SendDeviceToCloudMessagesAsync(DeviceClient deviceClient1, string deviceId)        {
            double avgWindSpeed = 10; // m/s
            Random rand...
