Esp32BleAndroid – ESP32 BLE Interface for Android

Esp32BleAndroid is a powerful interface bridge that connects your Android phone to an ESP32 via Bluetooth Low Energy (BLE). This asset allows you to integrate an ESP32 into your project as a plug-and-play gamepad—no coding required for basic setup!

For advanced users, it provides a seamless workflow to stream sensor data (Gyroscope, Accelerometer, GPS, etc.) and control external displays (LED, LCD panels) directly from Unity. By using the included ESP32 firmware and Unity sample scripts, you can bridge the gap between physical hardware and your digital world.

Key Features

· Plug-and-Play Gamepad: Quickly add ESP32 as a controller to your game.

· Bidirectional Data Transfer: Easily send and receive byte arrays between Unity and ESP32 via BLE.

· Ready-to-Use ESP32 Firmware: Includes pre-written Arduino code (e.g., a SIN function data generator) to get you started instantly.

· Comprehensive Unity Samples: Includes a 3D "tumbler" model to visualize XYZ data and a UI (InputField/Buttons) for sending data to the ESP32.

· Flexible Integration: Customize the provided Unity scripts and ESP32 code to connect any sensor or display panel.
