Question

How to use Bluetooth to exchange Data between 2 computers. Develop a program with Python to demonstrate this data exchange.

Answer 1

"""
Python script to send messages to a sever over Bluetooth
using PyBluez (with Python 2).

This is how we send data to other person over bluteooth
"""

import bluetooth # importing PyBlueZ

serverMACAddress = '00:1f:e1:dd:08:3d' #Mac Address of the server
port = 3 # Port number through which the data is transferred
s = bluetooth.BluetoothSocket(bluetooth.RFCOMM) #create a connection
s.connect((serverMACAddress, port)) #connect to the Mac Address through port

#looping infinite times until a quit command is received
while 1:
text = raw_input() # Note change to the old (Python 2) raw_input
if text == "quit":
break
s.send(text)
sock.close() # closing the connection

"""
Python script to receive messages from a client over
Bluetooth using PyBluez (with Python 2).

This is how we recieve messages over bluetooth connection

data = client.recv(size)
if data:
