Get Started

Android

Get the newest apk release and install, then well done!

It may ask for background location permission, you can deny it safely.
(Foreground) Location permission is required for scanning Bluetooth devices in newer Android system.

Windows

Get the newest release archive with "windows" in the file name,
extract to somewhere and run start.bat

GNU/Linux

You can get the "pure" release, extract it, fire a terminal inside and run:

python3 server.py

On Arch Linux based distros you may first install bluez, as it's often missing

sudo pacman -S bluez bluez-utils

Packaging is also on the way!

MacOS

For MacOS please install Python 3,
then install pyobjc and bleak via pip in terminal:

pip3 install pyobjc bleak

After that, fetch & use a "bare" release:

python3 server.py

Currently in Mac the browser will not pop up automatically. Please run manually and go to http://127.0.0.1:8095, or just click here.

Worth to Note

For all supported platforms,
You can also use "pure" edition once you have Python 3 installed,
or "bare" edition if you also managed to install bleak via pip.

If you like command-line, installing ImageMagick and Ghostscript could be very helpful.

See the releases now!
