# BLEClient

## Overview

This project demonstrates communication between two ESP32 devices using Bluetooth Low Energy (BLE) with the BLEServer library. The setup involves a server-client architecture where data is exchanged seamlessly between the two devices.

## Important

To ensure both codes work seamlessly together, please refer to the [BLEServer repository](https://github.com/Xtalism/BLEServer). It is crucial to make both the server and client codes work in tandem for successful communication and data exchange.

## Features

- **UUID Characteristics**: Utilizes UUID characteristics for sending and receiving data.

- **Potentiometer Data Processing**: The server reads and processes potentiometer data.

- **PWM LED Control**: The client uses the received data to control an LED with Pulse Width Modulation (PWM).

## Detailed Description

### Server Side

- Reads potentiometer data.

- Processes the data.

- Sends the processed data to the client via BLE.

### Client Side

- Receives data from the server.

- Uses the data to control an LED with PWM.

## Getting Started

1. **Hardware Requirements**:

   - Two ESP32 devices.

   - A potentiometer.

   - An LED.

2. **Software Requirements**:

   - Arduino IDE or PlatformIO.

   - BLEServer library.

3. **Setup**:

   - Connect the potentiometer to the server ESP32.

   - Connect the LED to the client ESP32.

   - Upload the respective server and client code to the ESP32 devices.

4. **Running the Project**:

   - Power on both ESP32 devices.

   - The server will start reading potentiometer data and send it to the client.

   - The client will receive the data and adjust the LED brightness accordingly.
