Mosquitto – the industry-standard MQTT broker – has been ported to ESP-IDF. Its lightweight version retains Mosquitto’s core functionality and security features to run on resource-constrained IoT devices. This MQTT broker is ideal for edge computing, testing, and standalone IoT deployments. In this article, we will do an overview and show you how to get started.

Espressif has launched the ESP32-C5, the first RISC-V SoC with dual-band Wi-Fi 6, Bluetooth 5 (LE), and IEEE 802.15.4 support. Designed for low-latency wireless applications, it features a 240 MHz CPU, LP-CPU, and rich peripheral options. Backed by ESP-IDF, the ESP32-C5 is now in mass production and ready for developers.

This two-part guide shows how to set up VS Code with the ESP-IDF extension to debug Espressif boards using JTAG. This first part covers the debugging process, hardware setup and connections, and starting the openOCD server.

This article demonstrates how to implement motor control and speed sensing on an ESP32-C6 using NuttX RTOS. It covers setting up MCPWM for motor control, ADC for potentiometer reading, and quadrature encoder for speed measurement. The implementation showcases NuttX’s real-time capabilities through a practical example using common peripherals and sensors.

Discover the ESP32-P4 EYE DevKit — a compact, camera-focused development board designed for real-time image processing and edge computing. Learn how this powerful, low-cost solution can accelerate your next smart camera or IoT project.

This article explores ESP FOURCC standard based on FOURCC (Four Character Code), a standardized 32-bit identifier used in multimedia for format consistency, reducing conversion overhead and debugging complexity. It highlights Espressif implementation in ESP-GMF, where esp_fourcc.h defines FOURCC values for video, audio, container, image, and pixel formats, optimizing efficiency in embedded systems.

This tutorial guides you through setting up a soft-AP using an Espressif module and ESP-IDF. It covers the process of creating a project, configuring Wi-Fi, and handling connection events through event loops and logging. Upon completion, you’ll be able to establish a soft-AP and manage Wi-Fi connections. It is the first step to building more advanced networking applications.

This guide helps manufacturers of wireless-enabled products based on Espressif modules understand the RED DA (EN 18031) cybersecurity requirements, identify their product’s category, and determine the right path to certification before launching in the EU market.

In this article, we’ll start with a quick overview of Ultra Low Power coprocessors (ULPs) in Espressif chips and how they can significantly reduce power consumption in your applications. Then, we’ll walk through a tutorial on how to use ULPs in practice!
