Bluetooth Low Energy (BLE) Project

This repository contains a Bluetooth Low Energy (BLE) project demonstrating how to use BLE in a Flutter/Dart Android app to communicate with an ESP32 device.

Features

• Example 0: Basic Connect Write - Connects to ESP32, sends data in the most easiest way.
• Example 1: Read/Write Example - Connects to ESP32, sends and receives data.
• Example 2: Multiple Characteristics - Reads and writes multiple BLE characteristics simultaneously, including real-time notifications (e.g., temperature sensor).
• Example 3: Large Data Transfer - Splits large packets (300 bytes) into smaller BLE-compatible chunks (17 bytes per packet) and reconstructs them on the app side.

Setup

1. Install dependencies (flutter_blue_plus: ^1.34.5 in pubspec.yaml).
2. Add necessary BLE permissions in AndroidManifest.xml.
3. Load the corresponding ESP32 BLE firmware.

Demo Videos

Short demonstration videos for each example are available in the Video/Final_video folder.
