Hello, unfortunately I don’t have any code on that exact subject. Can the ESP be connected with a serial connection to your Arduino?

I’ve never used that board before, but I assume that the ESP8266 and the ATMega chip are connected with TX and RX, so you can exchange serial data between the two chips..
