How to Configure WiFi with MicroPython?

Estimated read time 2 min read

To configure WiFi with MicroPython, you typically need to connect to your device using a serial connection, such as through a USB cable, and execute the necessary MicroPython commands to set up and connect to a WiFi network. Here’s a step-by-step guide:

  1. Connect to your MicroPython device: Connect your MicroPython device to your computer using a USB cable and establish a serial connection. You can use a serial terminal program such as PuTTY (Windows), Minicom (Linux), or screen (MacOS/Linux).
  2. Import the necessary modules: Once you’re connected, import the necessary modules for WiFi configuration. The specific module names may vary depending on your MicroPython firmware, but common modules include network and wlan.
import network
  1. Initialize the WiFi interface: Create an instance of the WLAN interface to work with. The exact syntax may depend on the MicroPython firmware you are using.
wifi = network.WLAN(network.STA_IF)
  1. Activate the WiFi interface: Enable the WiFi interface so that it can scan for and connect to networks.
  1. Scan for available networks (optional): You can scan for available WiFi networks and retrieve a list of networks and their details.
available_networks = wifi.scan()
for network in available_networks:
    print(network[0])  # Print the SSID (network name)
  1. Connect to a WiFi network: Use the connect() method to connect to a specific WiFi network by providing the network SSID and password.
ssid = "YourNetworkSSID"
password = "YourNetworkPassword"
wifi.connect(ssid, password)
  1. Check the connection status: You can check the connection status using the isconnected() method.
if wifi.isconnected():
    print("Connected to WiFi")
    print("Not connected to WiFi")

That’s it! By following these steps, you should be able to configure WiFi on your MicroPython device and establish a connection to a WiFi network. Remember to replace "YourNetworkSSID" and "YourNetworkPassword" with your actual network credentials.

Note: The specific implementation and available methods may vary depending on the MicroPython firmware you are using. Consult the documentation or resources specific to your device to find the appropriate commands and module names.
