Nothing / CMF Bluetooth sockets can be accessed by only one application at a time. Do not run other companion or monitoring apps while using BudsLink, such as:
earctl earweb Bluetooth Battery Meter GNOME Extension (disable the Nothing / CMF feature in the extension preferences)
Displays a circular battery widget, supporting either a single battery (headset) or three separate levels for Left, Right, and Case. The case battery is shown only when the buds report it, usually when the case is charging or when at least one bud is inside. Only certain models support ANC mode. Anti-Noise Cancellation (ANC)
Anti-Noise Cancellation Off Anti-Noise Cancellation On Transperancy Adaptive
App can detect Nothing and CMF buds / headsets among connected Bluetooth devices. It communicates over RFCOMM sockets to support features such as: Battery level reporting Control of ANC (Active Noise Cancellation) mode (if supported) Adaptive noise level customization (if supported) Configure Stem/Touch Equalizer, etc. Configure per device settings if supported
Device icons: Select from the available options for your headset type (single-battery or dual-battery devices). Case icon: For models that report a case battery, an additional case icon can be selected. Other settings are self explanatory similar to settings available in OEM Mobile App Nothing X
Some devices have not yet been tested and may show incorrect features in the configuration. Others may be missing entirely. If you notice missing devices or incorrect feature mappings, please open an issue on GitHub so we can add or correct them.
