在Python不安全RFCOMM连接

问题描述

我想建立从Android设备到树莓派没有配对蓝牙连接。在RPI所使用的语言是Python。我使用 createInsecureRfcommSocketToServiceRecord 从Android的连接。

然而，当这两个设备配对的连接才成立。有 listenUsingInsecureRfcommWithServiceRecord 的等效Python中？

树莓派code

  server_sock =的BluetoothSocket（RFCOMM）
server_sock.bind（（，PORT_ANY））
server_sock.listen（1）
端口= server_sock.getsockname（）[1]UUID =f3c74f47-1d38-49ed-8bbc-0369b3eb277cadvertise_service（server_sock，AquaPiServer
                   service_id为= UUID，
                   service_classes = [UUID，SERIAL_PORT_CLASS]
                   型材= [SERIAL_PORT_PROFILE]
                   ）    client_sock，CLIENT_INFO = server_sock.accept（）
    打印接受了连接，CLIENT_INFO
 

的Andr​​oid code

  BluetoothDevice类设备= blueAdapter.getRemoteDevice（RPi_MAC）;
的BluetoothSocket插座= device.createInsecureRfcommSocketToServiceRecord(UUID.fromString(\"f3c74f47-1d38-49ed-8bbc-0369b3eb277c\"));
blueAdapter.cancelDiscovery（）;
socket.connect（）;
 

解决方案

我是能够连接到树莓派不配对。为此，我不得不作出的RPI发现。然后我用 socket.connect（）从棉花糖运行我的Nexus。通过这样做，我能得到我的Nexus的MAC地址在RPI。唯一的问题是，每次我得到的配对请求我连接，但MAC地址是我想要的。

感谢您的输入大卫！

I would like to establish a bluetooth connection from an android device to a Raspberry Pi without pairing. The language used in RPi is Python. I am connecting using createInsecureRfcommSocketToServiceRecord from android.

However the connection is established only when the two devices are paired. Is there an equivalent of listenUsingInsecureRfcommWithServiceRecord in Python?

Raspberry Pi code

server_sock=BluetoothSocket( RFCOMM )
server_sock.bind(("",PORT_ANY))
server_sock.listen(1)
port = server_sock.getsockname()[1]

uuid = "f3c74f47-1d38-49ed-8bbc-0369b3eb277c"

advertise_service( server_sock, "AquaPiServer",
                   service_id = uuid,
                   service_classes = [ uuid, SERIAL_PORT_CLASS ],
                   profiles = [ SERIAL_PORT_PROFILE ],
                   )

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

Android code

BluetoothDevice device = blueAdapter.getRemoteDevice(RPi_MAC);
BluetoothSocket socket = device.createInsecureRfcommSocketToServiceRecord(UUID.fromString("f3c74f47-1d38-49ed-8bbc-0369b3eb277c"));
blueAdapter.cancelDiscovery();
socket.connect();

解决方案

I was able to connect to the Raspberry Pi without pairing. For this I had to make the RPi discoverable. Then I used socket.connect() from my Nexus running on Marshmallow. By doing this I was able to get the MAC address of my Nexus in the RPi. Only problem is that I get a pairing request every time I connect but the MAC address was what I wanted.

Thanks for your inputs David!
