# TrikiEmu: reconstructing the Żabka Triki BLE controller

> TrikiEmu recreates the Żabka Triki motion controller's BLE behavior on ESP32 firmware. It reproduces advertising identity, a Nordic UART Service profile and 14-byte IMU frames using findings from TrikiScope and Android HCI captures; PC tools feed keyboard, CSV or recorded motion to the emulator. The author reports that Żappka connects and reacts to movement on M5StickC Plus2.

## Requirements & limits

- **Prerequisites:** An ESP32 board, USB cable, phone with Żappka and a real Triki controller's BLE address are required.
- **Prerequisites:** PlatformIO Core builds the firmware; PC tools require Python 3 and pyserial.
- **Limits:** The author reports that gameplay responds to motion, while saving scores requires authentication from a real controller.
- **License:** MIT license.
