 This tutorial uses Quality of Service (QoS) level of 1 (equivalent to Solace “Guaranteed” or “Persistent” messages), which are at least once delivery messages. So first, let’s express interest in the messages by subscribing to a topic filter.
 
-A topic filter in MQTT differs from a Solace SMF topic subscription. Users can learn more about the differences between the two in the Topic Names and Filters section of [MQTT Specification Conformance – Operational Behavior](https://docs.solace.com/MQTT-311-Prtl-Conformance-Spec/Operational_behavior.htm).

 As with other tutorials, this tutorial receives messages asynchronously through callbacks. So define a callback using the 'MqttCallback' interface as outlined in the [publish/subscribe tutorial](../publish-subscribe/).
