Question

我正在尝试在我的覆盆子pi上创建一个程序，它接受来自Android设备的蓝牙连接。但构建总是失败。这是我的代码：

from bluetooth import *

def initServer():
server_sock=BluetoothSocket( RFCOMM )
server_sock.bind(("",PORT_ANY))
server_sock.listen(1)

uuid = "00001101-0000-1000-8000-00805F9B34FB"

advertise_service(server_sock, "Echo Server",
 service_id = uuid,
 service_classes = [ uuid, SERIAL_PORT_CLASS ],
 profiles = [ SERIAL_PORT_PROFILE ]
)
return server_sock

def getClientConnection(server_sock):
 print "Waiting for connection" 
 client_sock, client_info = server_sock.accept()
 print "accepted connection from ", client_info
 return client_sock

def manageConnection(socket):
 try:
   while True:
     data = socket.recv(1024)
     if len(data) == 0: break
     print "received [%s]" % data
     socket.send("Echo from Pi: [%s]\n" % data)
 except IOError:
   pass
server=initServer()
while  True:
client=getClientConnection(server)
manageConnection(client)
client.close()
server.close()
print "terminating..."

这是错误：

Traceback (most recent call last):
  File "bluetooth.py", line 1, in <module>
    from bluetooth import *
  File "/home/pi/Desktop/bluetooth.py", line 33, in <module>
    server=initServer()
  File "/home/pi/Desktop/bluetooth.py", line 4, in initServer
    server_sock=BluetoothSocket( RFCOMM )
NameError: global name 'BluetoothSocket' is not defined

已经安装了python-bluetooth。但是什么可能导致此错误，我该如何解决？

不要调用你的文件bluetooth.py，它会与你试图导入的模块混淆。

另请查看您的缩进，希望它与您提交的内容不同。

NameError：未定义全局名称“BluetoothSocket”
