@Aarav270150 This would be a starting point. > [@Pi Pico W to Pico W - Simple Communications](https://forum.core-electronics.com.au/t/pi-pico-w-to-pico-w-simple-communications/16188): > > Following success with my latest project. Main aim being to develop a simple way of getting two Pico W’s to communicate, thought I would share the Python code I developed. One Pico W sets itself up as a WiFi Access Point and listens for a connection from the other Pico W. The other Pico W connects to the Access Point, collects data and sends it. The Access Point responds with ‘success’ if data is received ok. The code here is the basic for the communications, whatever is done with the data … Just post in that thread.
