three ESP8266-01 send data in one mobile application made in MIT App Inventor

I'm a beginner when it comes to IP(ESP8266-01) web server connection in a mobile application.
I found this was a quiet frustrating/confusing because this server are the same in IP, plus that I know that in MIT app inventor I should call the web server of a particular IP.

Thus, my project is using 3 esp8266 to give 3 different data in a mobile application. Please help and guide me Thank you :slight_smile:
