# Scooter Link: a Xiaomi scooter client built from BLE protocol research

> Scooter Link implements an Android client for Xiaomi Electric Scooter 5 Pro and 5 Max using a reconstructed BLE authentication protocol. Its research log covers GATT characteristics and investigation of the ECDH P-256, HKDF-SHA256, and AES-CCM exchange; the app reads ride and battery data and controls supported settings.
