yay -S something-x
# or: paru -S something-x

Or via pip:

pip install something-x

Other distros

Ubuntu 24.04+

sudo apt install python3-gi python3-dbus python3-cairo gir1.2-gtk-4.0 gir1.2-adw-1
pip install something-x

Fedora 39+

sudo dnf install python3-gobject python3-dbus python3-cairo gtk4 libadwaita
pip install something-x

NixOS

nix run github:SoaOaoS/something-x

A flake.nix is included for reproducible builds.

Run from source

git clone https://github.com/SoaOaoS/something-x
cd something-x
pip install -e .
something-x

Usage

GUI

something-x

1. Splash — animated intro, main window appears after ~2 s
2. Home — lists all paired Bluetooth devices; Nothing / CMF devices get a NOTHING badge
3. Scan — tap SCAN FOR DEVICES to run a 30 s BlueZ discovery
4. Device page — tap a card to open controls:
   • Battery rings (L / R / Case) update in real time
   • ANC and EQ apply immediately over RFCOMM and are saved to your profile
   • Volume slider drives the A2DP sink via pactl
   • Firmware version and serial number appear after RFCOMM connects
5. Close — hides to background; run something-x again to reopen

CLI

Control your earbuds without opening the GUI:

# Battery levels
something-x --battery

# ANC mode
something-x --anc off
something-x --anc on
something-x --anc transparency

# EQ preset
something-x --eq balanced
something-x --eq bass
something-x --eq treble
something-x --eq voice

# Combine
something-x --anc on --eq bass

# Target a specific device by address
something-x --device AA:BB:CC:DD:EE:FF --battery

Development releases

The develop branch publishes pre-release builds to PyPI automatically as something-x-dev:

pip install something-x-dev
something-x-dev

Dev builds use version numbers like 1.3.0.dev42. Not for production use.

Protocol

Frame format: [SOF=0x55][ctrl:2 LE][cmd:2 LE][len:2 LE][FSN:1][payload][CRC16:2 LE]

All outgoing frames use ctrl=0x0160 with CRC16-ARC. The device silently drops SET commands if any frame in the session was sent without CRC.

Enable raw frame logging:

SOMETHING_X_DEBUG=1 something-x

Contributing

The RFCOMM protocol in nothing_app/protocol.py is reverse-engineered from the official Android APK. If your device uses different command IDs, channels, or ANC values, patches are very welcome — please include the raw RFCOMM dump (SOMETHING_X_DEBUG=1) in your issue or PR.
