RPi 3 Python 脚本 - 名称错误：未定义名称'BluetoothSocket'

Question

所以我对Python脚本相对较新，并且遇到了该代码，该代码应该在Raspberry Pi和Smart设备之间通过蓝牙配置WiFi。不幸的是，我一直遇到标题中列出的错误。我希望有人可以复制并运行代码并启发我为什么我会继续遇到这个错误。所有的帮助都非常感谢！

    # write wifi config to file
    f = open('wifi.conf', 'w')
    f.write('country=GBn')
    f.write('ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevn')
    f.write('update_config=1n')
    f.write('n')
    f.write('network={n')
    f.write('    ssid="' + ssid + '"n')
    f.write('    psk="' + psk + '"n')

        client_sock, client_info = server_sock.accept()

        server_sock.close()
        # finished config
        print 'Finished configurationn'

except (KeyboardInterrupt, SystemExit):
    print 'nExitingn'

此代码输出

Traceback (most recent call last):   File "test.py", line 128, in <module>
    server_sock=BluetoothSocket( RFCOMM )
NameError: name 'BluetoothSocket' is not defined

您可以向我们展示您的Python版本吗？

只是类型：

$ python --version

bluetooth lib似乎存在。但不是BluetoothSocket：尝试安装Bluez和Python-Bluez

$ sudo apt-get install bluez
$ sudo apt-get install python-bluez
