STM32 LWIP TCP Client

This project demonstrates how to set up a simple TCP client on the STM32 Nucleo-F746ZG board using the LWIP stack for network communication. The client connects to a server and sends JSON-formatted data over TCP. The application uses FreeRTOS for multitasking.

Project Overview

The primary function of this project is to send JSON data to a server over a TCP connection. The data includes a "Node ID" and a "Door Status", and the client attempts to connect to a remote server at 192.168.1.127 on port 8000. It uses the STM32F7 microcontroller along with the LWIP networking stack and FreeRTOS for task scheduling.

Features

• LWIP-based TCP client communication.
• Sends JSON data over TCP.
• Simple logging via snprintf for debug output.
• FreeRTOS task management.
• Network status monitoring to check if the network is up before connecting.

Hardware Requirements

• STM32 Nucleo-F746ZG or any compatible STM32 board.
• Ethernet connected to the network.
• UART (Serial) connection for debug output.
