  • Method Details

    • onMessageReceived

      void onMessageReceived(Mqtt5Client client, PublishReturn publishReturn)
      Called when an MQTT PUBLISH packet is received by the client.

      To take manual control of the publish acknowledgement for a QoS 1 message, call PublishReturn.acquirePublishAcknowledgementControl() within this callback. If you do so, the client will NOT automatically send the publish acknowledgement. You are responsible for calling Mqtt5Client.invokePublishAcknowledgement(Mqtt5PublishAcknowledgementControlHandle) later.

      If you do not call acquirePublishAcknowledgementControl() within the callback , the client will automatically send the publish acknowledgement after this callback returns.

      Parameters:
      client - The client that has received the message
      publishReturn - All of the data that was received from the server
