# LED Controller: a BanlanX BLE client with audio-feed protocol findings

> LED Controller uses BanlanX BLE commands to control SP611E-family LED strips from a desktop app. Its documentation maps GATT commands and state notifications, and reports probing an audio-feed message used by the controller’s music effects; included tools inspect advertisements, GATT state and Bluetooth captures.
