A Small script to lock/unlock (or any other action if you wish) Had a lot of issues with blueproximity so I started to search for alternatives and finally wrote this. The main idea is to have a lock/unlock within 1 meter like some proprietary software like NearLock (https://nearlock.me/) can do. The main alternative for linux is blueproximity (https://sourceforge.net/projects/blueproximity/) that use RSSI as a distance.

This is the result of documenting myself on different techniques and implementation to get distance from RSSI,

It's a very crude script working for now only with xscreensaver (I like GLmatrix screensaver ...) Even if it's not recommended to kill xscreensaver ... it's the only way I found to quickly unlock xscreensaver without messing with pam ...

This is a simple script that take MAC address as input Use Ctrl + C to exit the script or kill it's process.
