How to configure the MQTT Settings?

If you don't want to miss any MQTT messages, define the following settings:

• To avoid frequent disconnections from the Broker: Define TTL = 15 seconds on the client.
• To avoid losing messages: Define QoS = 1 and Clear Session = No on the client.
  Note: You might receive duplicate messages once in a while
