Mikrokontroler Jobs

For a project I need 3 ESP32's to "talk" to each other. 1 is the "gateway" between a smartphone and the 2 others. This "gateway-EPS32" must also have Wifi*. The 3 ESP's have to send simple (and very short) strings between them. So basically I need Arduino code for the 3 ESP32's. *When I go to a specific URL in my network, then the "gateway ESP32...
