bluetooth software

hi all
im trying to find some software that tells me and logs whaen a bluetooth devices comes in and out of range. the applications ive found so far have only told you when the device comes into range but not when it went out of range.
any help would be much appreciated.
thanks All.

 

thanks sammich
only problem is that the software is actually for the education department of tasmania australia
and i dont know but i highly doubt were going to have a couple of geeks listening to music as students mobiles come into range but ill run it past them see what they thinkhttp://images.macrumors.com/vb/images/smilies/smile.gifhttp://images.macrumors.com/vb/images/smilies/biggrin.gif
