【IT168 技术文档】创建一个应用程序能够让手机通过蓝牙连接到你PC。这个程序能够在手机上书写，并能在PC上接收到。

　　1、你需要使用 socket module :

　　1)让蓝牙扫描发现PC上的BT地址和服务，并连接上PC

　　2)创建一个能够触发一个文本输入框并能发送输入内容从蓝牙到PC终端的函数

　　示例代码：

　　# Copyright (c) 2005 Jurgen Scheible
　　# script that connects to the serial port of the PC
　　# and lets you send characters to the PC
　　import appuifw
　　import socket
　　import e32
　　def bt_connect():
　　global sock
　　sock=socket.socket(socket.AF_BT,socket.SOCK_STREAM)
　　target=''
　　if not target:
　　address,services=socket.bt_discover()
　　print "Discovered: %s, %s"%(address,services)
　　if len(services)>1:
　　import appuifw
　　choices=services.keys()
　　choices.sort()
　　choice=appuifw.popup_menu([unicode(services[x])+": "+x
　　for x in choices],u'Choose port:')
　　target=(address,services[choices[choice]])
　　else:
　　target=(address,services.values()[0])
　　print "Connecting to "+str(target)
　　sock.connect(target)
　　print "OK."
　　bt_typetext()
　　def bt_typetext():
　　global sock
　　test = appuifw.query(u"Type words", "text", u"")
　　if test == None:
　　exit_key_handler()
　　else:
　　sock.send(test)
　　bt_typetext()
　　def exit_key_handler():
　　script_lock.signal()
　　appuifw.app.set_exit()
　　appuifw.app.title = u"bt mob to PC"
　　script_lock = e32.Ao_lock()
　　appuifw.app.exit_key_handler = exit_key_handler()
　　bt_connect()
　　script_lock.wait()

　　if test == None:
　　exit_key_handler()
　　else:
　　# send the typed in characters over bluetooth to the PC
　　sock.send(test)
　　# call again the textinput field function to show the text input again
　　bt_typetext()
　　def exit_key_handler():
　　script_lock.signal()
　　appuifw.app.set_exit()
　　appuifw.app.title = u"bt mob to PC"

　　bt_connect()
　　script_lock.wait()

　　注意：

　　确认在你的PC蓝牙连接软件上进行了正确的设置：

　　鼠标右键点击蓝牙图标 -> 通信 -> 超级终端

　　选择选项标签，确定”Turn discovery on”被选择

　　选择 COM 端口标签，确定COM端口“连入”为可用，如果没有，创建一个新的COM端口

　　Create a Hyper terminal:

　　got to Accessories -> Communications -> Hyperterminal

　　give a name and choose an icon, press ok, then choose in the “connect using” field the COM port of your “incoming port”, press ok

　　make the Hyper teminal active by clicking the “call” button.

　　start now the python script on the phone.
