我已经尝试了其他评论中的所有建议，但都没有效果，我希望有人能帮助我。我已经为这个问题挣扎了三天了。我确信我的uuid是正确的，并且我知道清单中启用了蓝牙访问。

我正在尝试将我的android应用程序连接到运行在Fedora中的python服务器。它断断续续地工作，现在一点也不起作用。我收到的android异常通常是。。当在下面附加的代码中执行btSocket.connect()时，将抛出这些值。12-09 05:08:42.331: ERROR/BluetoothService(676): java.io.IOException: Service discovery failed

或者12-09 05:27:00.757: ERROR/BluetoothService(729): java.io.IOException: Service discovery failed

这是我的android蓝牙课程，应该负责一切。当主应用程序类收到套接字已连接到的消息时，线程将启动。我的蓝牙类基于http://www.anddev.org/viewtopic.php?p=35487#35487。package spin.halo;

下面是我的python代码的关键部分。我对这个密码很有信心。# pybluez library

import bluetooth

server_socket = bluetooth.BluetoothSocket( bluetooth.RFCOMM )

client_sockets = []

server_socket.bind(("",bluetooth.PORT_ANY))

port = server_socket.getsockname()[1]

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

print "Listening for devices..."

# advertise service

server_socket.listen(1)

bluetooth.advertise_service( server_socket, "Validation Host",

service_id = uuid,

service_classes = [ uuid, bluetooth.SERIAL_PORT_CLASS ],

profiles = [ bluetooth.SERIAL_PORT_PROFILE ],

)

# accept incoming connections

client_sock, client_info = server_socket.accept()

client_sockets.append(client_sock)

print "Accepted Connection from ", client_info
