/* * bluestep - locks your screen once you step out of the room, * provided that you took your bluetooth enabled * mobile phone with you. * * version 0.01 * * usage: bluestep <bdaddr> * * bdaddr - MAC address of the remote bluetooth device * * * (c) 2005 by Matthias Wenzel, licensed under GPLv2 * */
this tiny daemon peridically pings your bluetooth mobile, if doesn't get responses for a while it will lock your X desktop with "xscreensaver-command -lock".
hints:
figure out your <bdaddr> with:
# hciconfig hci0 up
# hcitool scan
Scanning ...
00:11:22:33:44:55 my_left_foot
#
try to ping your device (hciconfig/hcitool/l2ping come with your bluetooth libraries and tools):
# l2ping -c 3 00:11:22:33:44:55 Ping: 00:11:22:33:44:55 from 00:55:44:33:22:11 (data size 44) ... 0 bytes from 00:11:22:33:44:55 id 0 time 27.52ms 0 bytes from 00:11:22:33:44:55 id 1 time 32.05ms 0 bytes from 00:11:22:33:44:55 id 2 time 47.04ms 3 sent, 3 received, 0% loss
if the above command works you're probably set to run bluestep!
