I'm looking to use MQTT in an IoT project, but I can't find a clear explanation of the protocol's structure, message transmission process, QoS levels, and security mechanisms. Could you summarize how it works and its advantages? What experiences can you share on this topic? Also, I'm curious about the impact of different QoS levels on application performance.

I'm still not clear on how the Clean Session flag affects QoS persistence when a device goes offline and reconnects later. Can you share an example from your sensor setup on how you handle this?
