Simple Bluetooth Chat in Python

Bluetooth technology allows devices to communicate wirelessly over short distances. In this article, we will be discussing how to create a simple Bluetooth chat application using Python.

Setting up the environment

Before we start coding, make sure you have a Python environment set up on your computer. You will also need to install the PyBluez library, which provides support for Bluetooth communication in Python.

pip install pybluez

Creating the chat application

Now that we have the necessary libraries installed, let’s start creating our Bluetooth chat application. Below is a simple Python script that allows two devices to chat with each other over Bluetooth:

import bluetooth

server_socket = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
port = 1
server_socket.bind(("", port))
server_socket.listen(1)

client_socket, address = server_socket.accept()
print("Accepted connection from", address)

while True:
    message = input("You: ")
    client_socket.send(message)

    data = client_socket.recv(1024)
    print("Friend:", data.decode("utf-8"))

In this script, we create a server socket and listen for incoming connections. Once a client connects, we enter a loop where we continuously send and receive messages between the two devices.

Running the application

To run the chat application, run the script on one device and then run the script again on another device. Make sure the devices are paired and have Bluetooth enabled. Once the connection is established, you can start chatting with each other through the terminal.

Conclusion

Creating a simple Bluetooth chat application in Python is easy with the help of the PyBluez library. You can further customize the application by adding features such as encryption, file transfer, or group chat. Have fun experimenting with Bluetooth communication in Python!
