A MicroPython module for connecting to a WLAN (WiFi network)

The module defines a couple of methods to simplify connecting to a wireless network.

It makes a great companion to the microdot light-weight web server.

I've only tested it on a Raspberry Pi Pico, but it should work on most WiFi-capable MicroPython boards.

$ pip install mm_wlan

On a Pico W, you can either use Thonny's Manage packages.. feature, or copy the file mm_wlan.py onto the Pico's file system. You can do the latter in Thonny using the Save a Copy option.

hello.py a minimal web server example using microdot.

from microdot import Microdot
import mm_wlan

ssid = 'my network name'
password = 'my passord'

app = Microdot()  
mm_wlan.connect_to_network(ssid, password)

@app.route('/')
def index(request):
    return 'Hello, from Pico'

app.run(port=80)

Make sure that both microdot.py and mm_wlan.py are copied onto your Pico W and then change ssid and password before you run hello.py. You should see something like this in your Shell. Progress is marked by dots until a connection is made or it gives up.

connect_to_network(ssid, password, retries=10, verbose=True)

By default, the connection process will wait for 10 seconds before giving up. You can alter this by changing the optional retries paramater. If you don't want the connecting messages cluttering up your Python console, then set the optional verbose parameter to False.

is_connected()

This returns True if you are connected.

For a more complex example take a look at this example using the MonkMakes Plant Monitor.
