azure-iot-device-mqtt

#azure-iot-device-mqtt
Communicate with Azure IoT Hub from any device over MQTT.


Install

npm install -g azure-iot-device-mqtt@latest to get the latest (pre-release) version.

Getting Started

Create a device client:

``js
var clientFromConnectionString = require('azure-iot-device-mqtt').clientFromConnectionString;
var Message = require('azure-iot-device').Message;

var connectionString = '[IoT Hub device connection string]';

var client = clientFromConnectionString(connectionString);
`

Create a callback that sends a message and receives messages. When it receives a message it sends an acknowledgement receipt to the server:

`js
var connectCallback = function (err) {
if (err) {
console.error('Could not connect: ' + err);
} else {
console.log('Client connected');
var message = new Message('some data from my device');
client.sendEvent(message, function (err) {
if (err) console.log(err.toString());
});

client.on('message', function (msg) {
console.log(msg);
client.complete(msg, function () {
console.log('completed');
});
});
}
};
`

Open the connection and invoke the callback:

`js
client.open(connectCallback);
