安装pybluez
安装libbluetooth-dev避免报错
sudo apt-get install libbluetooth-dev
安装pybluez
sudo apt-get install pybluez
例子：pybluz 查询蓝牙
```python
import bluetooth
print("performing inquiry...")
nearby_devices = bluetooth.discover_devices(lookup_names = True)
print("found %d devices" % len(nearby_devices))
for addr, name in nearby_devices:
print(" %s - %s" % (addr, name))
```
1、import bluetooth
报错：no module named bluetooth
原因及解决方法：
> You've installed the Python 2 version of the bluez bindings. Either run the script using
python2 or install the Python 3 bindings. Since they aren't packaged, you would need to install them using pip:
python3 -m pip install pybluez
2、no module named gattlib
解决方法：
`sudo apt-get install libboost-python-dev libboost-thread-dev libbluetooth-dev libglib2.0-dev`
