# MQTT Client Example with TLS 1.3 Encryption on NUCLEO-F429ZI

This example demonstrates how to establish a secure connection to a MQTT broker using TLS v1.3 encryption on a NUCLEO-F429ZI board.

It subsequently establishes a Modbus TCP connection to a PLC, reads a holding register, and transmits its value to the MQTT broker. The register is then incremented by one, updated on the PLC, and this cycle repeats continuously.

## Features 🧰

* Secure connection to mqtt broker using TLS v1.3. 🔐

* Periodic MQTT message publishing (every second). ⏱️

* Periodic Modbus TCP communication. 🔄

* Utilizes NUCLEO-F429ZI board for implementation. 💻

## Requirements ✅

* **NUCLEO-F429ZI board:** This example is specifically tailored for the NUCLEO-F429ZI development board. 

* **IDE:** STM32CubeIDE 1.16.0 📥

* **MQTT broker:** You'll need an MQTT broker that supports TLS 1.3 connections. 🧩

* **PLC**  You'll need a PLC that support modbus tcp.

## How to Run 🚀

1. **Compile:**

    Compile the example code along with your chosen MQTT broker server and TLS version. 🧑‍💻

2. **Execute:**

    Flash the compiled code onto the NUCLEO-F429ZI board. 

    Run the code on the board. 🏃‍♀️

## Important Notes ⚠️

* **Network Connectivity:** Make sure you have an active internet connection to reach the server. 🌐

* **Broker Requirements:** The broker might have specific requirements for client authentication or topic subscriptions. Refer to their documentation if needed. 📖

* **Error Handling:** The example code might need to be enhanced with proper error handling and logging for production environments. 🐛
