git clone https://github.com/greatscottgadgets/libbtbb.git

Support for libbtbb is provided by project Ubertooth, either using the mailing list or via IRC in #ubertooth on chat.freenode.net
Bugs may be reported and tracked in the ticketing system. Although it often helps to mention the bug report on the Ubertooth mailing list to be sure that it has been seen.
