Exploring MQTT for IoT communication with ESP32

Among the many different protocols used in IoT, MQTT stands out as a powerful option. MQTT, with its lightweight and pub-sub messaging paradigm, has found its place as a go-to protocol for enabling efficient communication between resource-constrained devices such as ESP32 and remote servers.

This section takes an in-depth journey into the domain of MQTT communication, purposefully tailored for ESP32 projects. We will explore the mechanisms through which ESP32 can seamlessly engage with MQTT brokers, granting IoT devices the capability to share data, receive updates, and actively participate in the dynamic ecosystem of IoT.

What is MQTT?

MQTT is a lightweight and efficient messaging protocol designed for the efficient exchange of data between devices, especially in scenarios where bandwidth and resources are limited. It was originally developed by IBM in the late 1990s and has since become a widely adopted protocol in the realm...
