Hi folks. I recently purchased such a board (UNO + WiFi R3 ATmega328P + ESP8266)

and I just can’t write a sketch for transferring data from the ESP8266 module to the ATmega328 module. I am getting weather data from a website and I need to transfer this data to ATmega328. In other discussions, I read that it was advised to use the Serial, but I'm new and can't figure out how to write such a sketch. I would be very grateful if you have come across this and you have a ready-made sketch or indicate where you can find information for its implementation. Thank you

Can you link the exact part number, manual, or amazon listing of the ESP8266 module you are using?

Different ESP8266 modules have different interfaces. Once we know the interface, we can point you in the right direction of how to write your program.
