创建一个应使用程序可以让手机通过蓝牙连接到你计算机。这个程序可以在手机上书写，并能在计算机上接收到。
1、你需要使用 socket module :
1)让蓝牙扫描发现计算机上的BT地址和服务，并连接上计算机
2)创建一个可以触发一个文本输入框并能发送输入内容从蓝牙到计算机终端的函数

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 计算机"

script_lock = e32.Ao_lock()

appuifw.app.exit_key_handler = exit_key_handler()

bt_connect()

script_lock.wait()

注意：
确认在你的计算机蓝牙连接软件上进行了 准确的设置：

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”为可使用，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.
