libbtbb
libbtbb是蓝牙基带解码库，源自GR-Bluetooth项目。 它可用于从Ubertooth设备以及GR-Bluetooth / USRP中提取蓝牙数据包信息。

编译和安装
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
gr-bluetooth
gr-bluetooth是GNU Radio的蓝牙基带层实现，用于实验和教授学生软件定义无线电，它不应该用于蓝牙通信，因为它不是一个完整的软件堆栈。
gr-bluetooth网站是：http://gr-bluetooth.sourceforge.net
https://github.com/greatscottgadgets/gr-bluetooth
编译和安装
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
编译完成生成gnuradio-companion模块
