Azure IoT Development Cookbook

How to do it...

In this section we are going to build the IoT protocol gateway:

1. Connection with IoT Hub:

{  cmd: 'connect',  protocolId: 'MQTT', // Or 'MQIsdp' in MQTT 3.1.1  clean: true, // Can also be false  clientId: 'myFirstDevice',       // Device Id registered in IoT Hub  keepalive: 0, // Seconds which can be any positive number, with 0 as the default setting  username: 'IoTHubCookBook.azure-devices.net/myFirstDevice/api-version=2016-11-14', // 'hostname/deviceId/version'  password: 'LKCXsBKMKISTjr3ii08UXgIpELxy8/38EiMuxNAiqek=', // SharedAccessKey  will: {    topic: 'devices/myFirstDevice/messages/events/'  }}

2. Process the message ingested into IoT Hub:

 readonly string iotHubD2cEndpoint = "messages/events";readonly string iotHubD2cEndpoint = "messages/events"; ...
