This is interesting and has potential, but right now it's just getting the hardware going with a better antenna. It'll be much more interesting to see what he finds over the course of a month or so.
There is much better hardware out there. The Ubertooth devices can pick up BLE, and can also plug into basically any antenna you want. It's been a while since I played with it, but a few years ago my ubertooth was grabbing LAPs without difficulty. It's not a dirt-cheap device (150$ all in) but is open and available from a variety of sources.<p><a href="https://github.com/greatscottgadgets/ubertooth/wiki/Capturing-BLE-in-Wireshark" rel="nofollow">https://github.com/greatscottgadgets/ubertooth/wiki/Capturin...</a>
David: If you are reading this, your site has very annoying "smooth scroll" that breaks scrolling for all mac users and also breaks the "back" shortcut on mac trackpads.
