这是我在Raspberry Pi 3 Model B上运行以下脚本时得到的错误 .

import bluetooth

name="bt_server"
target_name="siggen"
uuid="222705e1-e1e6-47f5-aa92-1c5ae849f3f1"

def runServer():
    serverSocket=bluetooth.BluetoothSocket( bluetooth.RFCOMM )
    port=bluetooth.PORT_ANY
    serverSocket.bind(("",port))
    print "Listening for connections on port: ", port   
    serverSocket.listen(1)
    port=serverSocket.getsockname()[1]

    #the missing piece
    bluetooth.advertise_service( serverSocket, "SampleServer",
                       service_id = uuid,
                       service_classes = [ uuid, bluetooth.SERIAL_PORT_CLASS ],
                       profiles = [ bluetooth.SERIAL_PORT_PROFILE ] 
                        )

    inputSocket, address=serverSocket.accept()
    print "Got connection with" , address
    data=inputSocket.recv("1024")
    print "received [%s] \n " % data    
    inputSocket.close()
    serverSocket.close()  

runServer()

我有bluez版本5.37 . 我已经按照这些链接（link1）和（link2） . 他们似乎没有解决问题 .

我可以使用以下终端命令将我的android连接到raspberry pi

sdptool add sp

它没有给出任何回应 .

sudo rfcomm听hci0＆

设备已连接（使用blueterm app）

cat / dev / rfcomm0

此端口用于接收数据

此外，以下脚本有效

import bluetooth

server_sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )

port = 1
server_sock.bind(("",port))
server_sock.listen(1)

client_sock,address = server_sock.accept()
print("Accepted connection from ",address)

data = client_sock.recv(1024)
print("received [%s]" % data)

client_sock.close()
server_sock.close()

因此蓝牙功能完全正常 . 我唯一的问题是配置文件 . 我无法弄清楚问题是什么 . 任何形式的帮助表示赞赏 .

在此先感谢您的帮助！
