Mega2560 Wifi / ESP8266 Bi-directional Comms
I struggled for hours with this and finally sussed it all out. If you are one of those who is ready to give up then msg me and I will sort you out. For example, you may want a webserver running on the ESP8266 while the ATMega is collecting sensor data for forwarding to the webserver. You may need to pass the IP address of the webserver back to the ATMega for display so that you can connect to it (or use the cloud of course).
