Class MqttConnector

  • public class MqttConnector
extends java.lang.Object
    This helper class wraps a connection to an MQTT broker.

    One main feature of this class is to retry the initial connection to an MQTT broker. A feature that is unfortunately not present in Eclipse Paho. After the first successful connection, Paho reconnects on its own in case of a lost connection.
