Bluetooth 在Raspbian中更改蓝牙mac地址

嗨，我需要从我的设备更改蓝牙mac地址。我已经从下载了bdaddr实用程序！我编译了它

然后

wget -U "Mozilla" http://www.petrilopia.net/wordpress/wp-content/uploads/bdaddrtar.bz2
...
mv bdaddrtar.bz2 bdaddr.tar.bz2
tar xvjf bdaddr.tar.bz2
cd bdaddr 
sudo apt-get install libbluetooth-dev
...
make

为什么我不能写地址？有什么想法吗

---

感谢

bdaddr实用程序不是bluez软件包的一部分，因为它使用特定于制造商的代码，因此不适用于所有设备
