Usage

Example code can be found in the examples directory.

Publisher

Simple publisher which connects to the MQTT broker and periodically sends a message. Implicitly it connects to 127.0.0.1:1883

auto settings = Settings();
settings.clientId = "test publisher";

auto mqtt = new MqttClient(settings);
mqtt.connect();

auto publisher = runTask(() {
        while (mqtt.connected) {
            mqtt.publish("chat", "I'm still here!!!");
            sleep(2.seconds());
        }
    });

Subscriber

Simple subscriber which connects to the MQTT broker, subscribes to the topic and outputs each received message. Implicitly it connects to 127.0.0.1:1883

class Subscriber : MqttClient {
    this(Settings settings) {
        super(settings);
    }

    override void onPublish(Publish packet) {
        super.onPublish(packet);
        writeln("chat: ", cast(string)packet.payload);
    }

    override void onConnAck(ConnAck packet) {
        super.onConnAck(packet);
        this.subscribe(["chat"]);
    }
}

auto settings = Settings();
settings.clientId = "test subscriber";

auto mqtt = new Subscriber(settings);
mqtt.connect();
