How to Get Started with Network Programming in MicroPython?

Estimated read time 2 min read

To get started with network programming in MicroPython, you can follow these steps:

  1. Connect to a Wi-Fi network: Before you can perform network operations, you need to connect your ESP8266 board to a Wi-Fi network. Use the following code to connect to a Wi-Fi network:
import network

ssid = "your_wifi_ssid"
password = "your_wifi_password"

wifi = network.WLAN(network.STA_IF)
wifi.connect(ssid, password)

while not wifi.isconnected():

print("Connected to Wi-Fi")

Replace "your_wifi_ssid" with the SSID of your Wi-Fi network and "your_wifi_password" with the password for your network.

  1. Basic web server example: Let’s create a simple web server that listens for incoming HTTP requests and sends a response. Use the following code:
import socket

def handle_request(client_sock):
    request = client_sock.recv(1024)
    response = b"HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\nHello, world!"

server_sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_sock.bind(('', 80))

print("Web server started")

while True:
    client_sock, addr = server_sock.accept()

This code sets up a web server that listens on port 80. When a client makes an HTTP request, the server responds with a simple HTML message.

  1. Accessing URLs with the urequests module: MicroPython includes a lightweight HTTP client module called urequests. You can use it to make HTTP requests and retrieve the response. Here’s an example:
import urequests

response = urequests.get("")

In this example, the get() function sends an HTTP GET request to and retrieves the response. The response content is then printed.

These are just a few examples to get you started with network programming in MicroPython. With these basics, you can explore more advanced features and libraries, such as MQTT for IoT communication, socket programming for custom protocols, or interacting with REST APIs.
