MQTT 5.0

MQTT 5.0 is a communication protocol designed for lightweight, efficient messaging between devices over the internet, often in IoT (Internet of Things) setups. It allows multiple devices to send and receive messages in a pub/sub (publish/subscribe) system, meaning one device can publish data, and others can subscribe to receive it. Version 5.0 introduces improved features like better error handling, clearer communication, and more control over message delivery, making device interactions more reliable and flexible. This protocol is ideal for real-time data exchange in environments with limited bandwidth or resource constraints.
