I have an ESP8266 with a nodeMCU firmware installed on it and an Arduino Nano.
What I would like to do, is send some data from a web server to the ESP8266 and then to the Arduino via serial connection.
Something like the following example : http://randomnerdtutorials.com/esp8266-web-server/
... but with data that the user could enter and not just two GPIO buttons.
I tried to find a LUA script that does that but I was not successful.
Does someone have a similar script?
Thank you
