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

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()

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.
