# OpenNoiseRep: a BLE client for the Noise REP fitness band

> OpenNoiseRep implements a BLE client for the Noise REP band, with desktop, menu-bar and command-line views for historical health data and local CSV or JSON export. Its protocol notes reconstruct GATT characteristics, chunk framing and commands from a vendor sync capture and live probing.
