Turn your retro handheld into the ultimate Bluetooth peripheral.
BlueMoon is a Kotlin Multiplatform (KMP) application that transforms your Android-based retro handheld into a fully functional Bluetooth HID peripheral.
Unlike other solutions, BlueMoon requires zero server-side software.
Your device will be recognized as a native hardware controller, keyboard, or mouse by the host system. Whether you're playing games on your PC, navigating a media center, or controlling a tablet, BlueMoon bridges the gap between your handheld's physical buttons and your other devices.
- Game Controller: Full gamepad mapping for retro titles or modern gaming.
- Touchpad Mode: Use your handheld's screen as touchpad for your PC/Mac.
- Remote Keyboard: Type long URLs or searches on your host device using your handheld.
- Media Control: Dedicated volume and playback controls for a seamless "couch-to-TV" experience.
- Bluetooth Classic: High compatibility with low latency (250Hz).
