MQTT Topics

Below are the topics which the car/app subscribes from and publishes to. Idea being that once information is received through a sensor it is published on the sensor's topic, then the app subscribing to the topic gets that information to display it.

• Publish = send to broker via topic
• Subscribe = receive from broker via topic
