Interesting... I personally have not seen this. Thank you for the pointer. It looks like custom hardware running custom firmware. This should be able to give full access to baseband. Still kinda pricey. Ubertooth one hardware sells for $120 at sparkfun. That's 3x price of raspberry pi 2/3 :) for a fraction of general usability :) could make an relatively inexpensive Bluetooth scanner though. 

Thanks !
