Scan for wireless networksĪs an example of how the network module provides access consider the following code Network services are then available for use via the socket module. Drivers for the Pico W hardware is available within this module and it can be used to configure the network interface. The network module includes functionality in the form of network drivers and routing configuration which is specific to the MicroPython. You can download it for free (or donate if you wish) from here. I've written this short explanation as part of the much larger book ' Raspberry Pi Pico Tips and Tricks '. With the release of the Pico W with WiFi built in, this should be the go-to option for connecting to a WiFi network if you’re using a Pico. It’s possible to use a standard Pico connected to an ESP8266 or similar to enable WiFi connectivity, but in enabling this I found there was more heartache than I cared to endure.
The wireless interface is connected via a Serial Peripheral Interface (SPI) to the RP2040 microcontroller. The antenna is a tuned cavity design which is licensed from ABRACON (formerly ProAnt). Software enabled Access Point (SoftAP) which supports up to 4 clients.The Raspberry Pi Pico W includes an on-board 2.4GHz wireless interface which has the following features:
