我正在尝试用python创建一个rfcomm服务器进程,它可以在不需要配对的情况下使用。最初,我从pybluez文档中获取了两个示例脚本:
服务器:
# file: rfcomm-server.py
# auth: Albert Huang <[email protected]>
# desc: simple demonstration of a server application that uses RFCOMM sockets
#
# $Id: rfcomm-server.py 518 2007-08-10 07:20:07Z albert $
from bluetooth import *
server_sock=BluetoothSocket( RFCOMM )
server_sock.bind(("",PORT_ANY))
server_sock.listen(1)
port = server_sock.getsockname()[1]
uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"
advertise_service( server_sock, "SampleServer",
service_id = uuid,
service_classes = [ uuid, SERIAL_PORT_CLASS ],
profiles = [ SERIAL_PORT_PROFILE ],
# protocols = [ OBEX_UUID ]
)
print "Waiting for connection on RFCOMM channel %d" % port
client_sock, client_info = server_sock.accept()
print "Accepted connection from ", client_info
try:
while True:
data = client_sock.recv(1024)
if len(data) == 0: break
print "received [%s]" % data
except IOError:
pass
print "disconnected"
client_sock.close()
server_sock.close()
print "all done"
客户:
# file: rfcomm-client.py
# auth: Albert Huang <[email protected]>
# desc: simple demonstration of a client application that uses RFCOMM sockets
# intended for use with rfcomm-server
#
# $Id: rfcomm-client.py 424 2006-08-24 03:35:54Z albert $
from bluetooth import *
import sys
addr = None
if len(sys.argv) < 2:
print "no device specified. Searching all nearby bluetooth devices for"
print "the SampleServer service"
else:
addr = sys.argv[1]
print "Searching for SampleServer on %s" % addr
# search for the SampleServer service
uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"
service_matches = find_service( uuid = uuid, address = addr )
if len(service_matches) == 0:
print "couldn't find the SampleServer service =("
sys.exit(0)
first_match = service_matches[0]
port = first_match["port"]
name = first_match["name"]
host = first_match["host"]
print "connecting to \"%s\" on %s" % (name, host)
# Create the client socket
sock=BluetoothSocket( RFCOMM )
sock.connect((host, port))
print "connected. type stuff"
while True:
data = raw_input()
if len(data) == 0: break
sock.send(data)
sock.close()
当我在Windows上运行服务器脚本时,一切都按我所希望的方式运行——不需要配对。在这个阶段,一切看起来都很有希望。
但是,我需要在Debian挤压下运行服务器进程。当我在Debian上测试时,客户机连接被拒绝。在系统日志中,有来自bluetouthd的失败链接键请求和pin请求的消息。
版本信息:
碧蓝0.18
蟒蛇2.6
蓝字4.66
连接两端的蓝牙2.0版硬件
This discussion似乎建议如果我可以调整服务器套接字上的安全级别,那么将禁用配对,并且一切都将按预期工作。但是,我不清楚如何使用pybluez,或者即使可能。
我曾尝试过使用各种bt_security*常量调用setsockopt(),以及获取最后一个pybluez并调用setl2capsecurity(),但没有取得任何进展。
用pybluez可以实现吗?
最佳答案
这是debian-squence-bluez默认配置的问题。
如果其他人遇到此问题,请通过编辑/etc/bluetooth/main.conf禁用PNAT插件:
DisablePlugins = pnat
然后重新启动蓝牙。
$ sudo invoke-rc.d bluetooth restart
不需要更改pybluez代码。
