RPi 3 Python腳本 - 名稱錯誤：名稱'BluetoothSocket'未定義

Question

因此，我相對較新的python腳本，我碰到這個代碼，應該配置Wi-Fi覆蓋覆盆子pi和智能設備之間的藍牙。不幸的是，我一直遇到標題中列出的錯誤。我希望有人可以複製並運行代碼，並啓發我爲什麼我一直遇到這個錯誤。所有幫助非常感謝！

    f.write('country=GB\n')

except (KeyboardInterrupt, SystemExit):

此代碼輸出

    server_sock=BluetoothSocket(RFCOMM) 

NameError: name 'BluetoothSocket' is not defined

你能告訴我們你的Python版本？

只需鍵入：

$ python --version 

bluetooth lib中似乎存在。但是，並非BluetoothSocket：嘗試安裝的bluez和python-bluez的

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