val client = MqttAsyncClient("tcp://mqtt.eclipseprojects.io:1883", UUID.randomUUID().toString())

client.orchestrate {

    onConnectComplete { isReconnect, serverURI ->

        log.info("Connected to $serverURI")

    }

    onMessageArrived { topic, message: MqttMessage ->

        log.info("Message arrived on topic $topic")

    onDeliveryComplete {

    }

    catchError { exception ->

        log.error("Failed to connect to broker due to ${exception?.message}")

    }

}

```

```kotlin

    onSuccess {
