I've searched the internet quite a bit and all I find is how to make two esp8266 communicate. What I am trying to do is connect a single esp8266 to the arduino and have a two-way communication between them.
I want to send and receive data on both the Arduino and ESP8266. The concept is to send data to the esp8266 over WiFi connection and then send that data to the Arduino. The Arduino will manipulate it and send it back over WiFi.
I feel like this would be a common beginner example to have a two-way communication over a TX/RX connection, but I can't seem to find any. All examples I find are strictly one as sender and other as receiver.
