MQTT is a protocol specializing IOT devices. It involves a Publish-Subscribe mode of communication

Go MQTT: Understanding MQTT with Go

This repository is aimed at understanding MQTT (Message Queuing Telemetry Transport) using the Go programming language. MQTT is a lightweight messaging protocol commonly used in IoT (Internet of Things) and other resource-constrained environments for communication between devices.

Overview

The repository provides examples and implementations of various MQTT functionalities using Go, covering topics such as:

• Connecting to an MQTT broker
• Publishing messages to topics
• Subscribing to topics and receiving messages
• Quality of Service (QoS) levels
• Retained messages
• Last Will and Testament (LWT)
• TLS (Transport Layer Security) encryption for secure communication

Installation

To use the examples in this repository, you need to have Go installed on your system. You can download and install Go from the official website.

Clone the repository to your local machine

• using ssh:

    git clone [e-mail]:vacaramin/Go-MQTT.git

• using https:

    git clone https://github.com/vacaramin/Go-MQTT.git

Usage

Install necessary dependencies:

    go mod tidy

Run the example files to see MQTT functionalities in action:

    go run examples/publish.go
    go run examples/subscribe.go

Make sure to configure the MQTT broker details (e.g., broker address, port, credentials) in the example files before running them.
