In 2013 I released the "Bluetooth Device Database" project and spoke about it at DEFCON 21. Recently, I grew tired of paying my EC2 bill and decided to retire the project. All of the source code used to create the clients and server is still available in my bluetoothdatabase github repo.
The slides and videos from the DEFCON 21 talk can be found here.
If you have any questions about the project feel free to contact me.
