Introduction MQTT (Message Queuing Telemetry Transport) is a lightweight communication protocol based on the publish/subscribe model, specifically designed for low bandwidth, unreliable, or high-latency network environments. It was released by IBM in 1999 and is suitable for connecting remote devices, particularly Internet of Things (IoT) devices. MQTT provides real-time, reliable message transmission services by reducing … Read more

This article is translated from: https://pimylifeup.com/raspberry-pi-mosquitto-mqtt-server/ with some understanding and modifications, and additional settings for enabling remote access. Introduction to MQTT MQTT stands for Message Queuing Telemetry Transport, a network messaging protocol commonly used for message transmission between IoT devices. To enable our Raspberry Pi to support the MQTT protocol, we will use server software … Read more
In this article, we learn how to transmit MQTT messages from ESP8266 / NodeMCU to a Raspberry Pi running an MQTT broker. Our NodeMCU will read the light levels through a light-dependent resistor (LDR) and then transmit this information to the Raspberry Pi over Wi-Fi using MQTT. NodeMCU is an open-source IoT platform. It is … Read more
MQTT is a messaging protocol developed by IBM. MQTT is a lightweight publish-subscribe messaging transport protocol designed for M2M and IoT connections. Mosquitto is an open-source message broker that implements the MQTT v3.1 protocol, providing a lightweight, publish/subscribe messaging model that makes short message communication between devices simple and easy to use. If you are … Read more
