A comprehensive Bluetooth communication library for Arduino and ESP32 that communicates with the DIYables Bluetooth STEM mobile app on Android and iOS.
📲 Download the app:
- Android: Google Play Store
- iOS: App Store (coming soon)
This library provides clean architecture with platform abstraction supporting both BLE (Bluetooth Low Energy) and Classic Bluetooth. Upload an Arduino sketch, connect via the mobile app, and start interacting with your hardware project — no mobile coding required.
- Multiple App Types: Joystick, Plotter, Pin Control/Monitor, Chat, and Monitor
- Clean Architecture: SOLID principles with platform abstraction layer
- Extensible Design: Easy to add custom app types
- BLE & Classic Support: Works with ArduinoBLE, ESP32, and more
- Ready Examples: Complete working examples for each app type
- Type-Safe API: Clear interfaces with callback-based event handling
