# BudsCtl: reconstructing SoundPEATS earbud controls

> BudsCtl reconstructs SoundPEATS Air4 Pro GAIA V2 controls for a macOS menu bar app that changes noise mode and reads each earbud's battery level. Its documentation identifies the BLE service, command framing, and response behavior; a separate Samsung RFCOMM implementation draws on a cited protocol reference.
