regarding the license, this is more of a hobby project, so GPL is perfect.

Looking at hci.{c,h}, there is (except for the license) not a single 
comment that would help explain things (to bluetooth-newcomers). The 
functions might have descriptive names, but I'm missing the bigger picture.

Reading ibeacon.c, I get the impression the code is made for sending 
advertisements, not for receiving them. I might be wrong though, there's 
no comments either. None of the other filenames in tools/ made me hope I 
could find sample code for receiving non-connectable advertisements.

Marcel, could you either point me to some sample code, or help me 
understand hci.c (or list the required steps) so that I can write my own?

thanks!
