Overview

BlueDo - Bluetooth proximity automation

Lock your desktop, mute music or run any other command when leaving your PC. There are dozens of apps like this. This one just aims to make it beautiful, modern and easy.

Not all bluetooth devices works for this. Some devices randomizes the bluetooth address as a privacy feature, some disconnects to save power. If you have trouble using your phone, try a headset, watch, etc.

Only Bluetooth is supported, not Bluetooth Low-Energy (BLE).

System changes

Note that this app will make these changes to your power management:

• Enable screen lock: org.gnome.desktop.screensaver lock-enabled true
• Set delay from screen blacking to locking to zero: org.gnome.desktop.screensaver lock-delay 0
• Set screen saver timeout to 10 seconds when device is away, 5 minutes when device is present: org.gnome.desktop.session idle-delay 600

TODO

• Check for dependencies on startup
• Default lock / unlock ON.
• Keep two instances from running at the same time.
• Minimize to tray, instead of having both minimize and minimize to tray.
• Stop device scanning when minimized
• Change to dynamic widget layout instead of fixed.
• Change preferences button to proper burger menu.
• Move media files to some other dir?
• Unit tests
• When on xfce:
  • for bluetooth settings, open blueman-manager
  • to lock/unlock change xscreensaver timeout, to match functionality from gnome

Development docs

• scan for devices: bluetoothctl devices

• rssi for device: hcitool rssi ff:ff:ff:ff:ff:ff (unstable?)

• Version below .56 needs Python < 3.9, bluetoothctl ~5.50 or newer.

• hard locking: lock when no signal

• soft locking: set screensaver timeout to 10 seconds when no signal
