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.
