This repository “Wireless Communication Code Examples for Raspberry Pi Pico W, by” is a collection of the code examples.
It includes MicroPython code for the micro IoT sensor devices which send sensor values via UDP and a micro LCD device which receives from them to display the sensor values on it.

The picture below is a example of a micro IoT sensor on a breadboard.

Following picture is the receiver for the above board.


The sensor values which send from the micro IoT Sensors are displayed on the LCD.


A communication protocol CSVxUDP is used for them. If your LCD device cannot recieve UDP packets, it might be discarded by your Wi-Fi router. In this case, please try to use “”.
Or if there are someting wrong in the broadcasted UDP behaviors, use unicast address such as “” for transmitter side of and
