Libbtbb is the Bluetooth baseband library used by the Ubertooth and gr-bluetooth projects. It is freely available under the GPL v2 license.
Libbtbb is built from source using either a released archive or the latest code from our git repository. To get started, do either of the following:
git clone git://git.code.sf.net/p/libbtbb/code libbtbb
git clone http://git.code.sf.net/p/libbtbb/code libbtbb
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.
