MQTT is a lightweight messaging protocol for IoT devices to communicate over a network.

• MQTT uses a publish/subscribe model where clients can publish messages to a topic and subscribe to receive messages on that topic.

• It is designed for low-bandwidth, high-latency networks, making it ideal for IoT devices with limited resources.

• MQTT brokers act as intermediaries that route messages between publishers and subscribers.

• QoS levels (0, 1, 2) can be used to control the delivery guar...read more
