Configure and control any Samsung Galaxy Buds device and integrate them into your desktop.
Aside from standard features known from the official Android app, this project helps you to release the full potential of your earbuds and implements new functionality such as:
If you're looking for older firmware binaries, have a look here: https://github.com/timschneeb/galaxy-buds-firmware-archive
There are several Linux packages available:
Get binaries for Windows in the release section. Please read the release notes before installation.
Download the desktop version here:
Download the Android mobile version here (paid):
Universal binary packages for all Linux distributions. The Flatpak version does not support autostart unless it is set up manually. You can use galaxybudsclient /StartMinimized to launch the app silently during startup.
Available for download on FlatHub: https://flathub.org/apps/me.timschneeberger.GalaxyBudsClient
flatpak install me.timschneeberger.GalaxyBudsClient
Note: Flatpaks are sandboxed. This application can only access
~/.var/app/me.timschneeberger.GalaxyBudsClient/by default.
An AUR package for Arch Linux maintained by @joscdk is also available:
yay -S galaxybudsclient-bin
The Windows package is also available to install with Windows Package Manager (winget)
winget install timschneeb.GalaxyBudsClient
In order to use Bluetooth wireless technology, a device must be able to interpret specific Bluetooth profiles that enable Bluetooth devices to communicate efficiently with each other.
The Galaxy Buds define two Bluetooth profiles: A2DP (Advanced Audio Distribution Profile) for audio streaming/controlling and SPP (Serial Port Profile) for transmitting binary streams. Manufacturers often use this profile (which relies on the RFCOMM protocol) to exchange configuration data, perform firmware updates, or send other commands to the Bluetooth device.
Even though the A2DP profile is standardized and documented, the format of the binary data exchanged by this RFCOMM protocol is usually proprietary.
To reverse-engineer this data format, I started by analyzing the structure of the binary stream sent by the earbuds. Later on, I also disassembled the official Galaxy Buds apps for Android to gain more insight into these devices' inner workings. You can find some (incomplete) notes I took down below. Check the source code to get more detailed information on the structure of the protocol.

While taking a closer look at the Galaxy Buds Plus, I also noticed some unusual features, such as a firmware debug mode, an unused pairing mode, and a Bluetooth key dumper. I documented these findings here:
Galaxy Buds Plus: Unusual features
Currently, I'm looking into modifying and reverse-engineering the firmware for the Buds+. At time of writing I have created two tools to fetch and analyze official firmware binaries. Check them out here:
