# G2CC: a replacement Even G2 client built from Bluetooth traffic analysis

> G2CC reconstructs communication with Even Realities G2 smart glasses through a replacement Android BLE client and a PC-side display compositor. Its protocol documentation describes captured Bluetooth frames and the display, input and battery exchanges used by the client.
