#34031 I have two Arduino boards and two ESP8266 modules with the NodeMCU firmware, and I want to make this: One Aruino will be connected to one module and a vibration sensor, and when this sensor detects some vibration, it will send some data using the ESP8266 module as a server, then, the other Arduino will recieve the data with the other ESP module and display a message to a LCD screen.

I've already programmed the WiFi modules as a server and as a client using NodeMCU firmware and LuaUploader. The issue I have is that I don't know how to make a program in the Arduino IDE that communicate both Arduino boards using the ip adress assigned to both ESP modules, can you help me? Thanks
