#NodeMCU - Guide to Solve different kinds of Problems

Are you making an IoT Android/iOS app to control NodeMCU (ESP8266)? I recommend you to use WebSocket to communicate between App and NodeMCU. If you are using HTTP web-server then it will be slow communication between Chip and Mobile App therefore use WebSocket instead.

In this example, we are going to show you how to show live data like temperature, humidity, and Heat Index from DHT11 Sensor on a mobile App using NodeMCU (ESP8266). We have used WebSocket to transfer data from NodeMCU to Mobile App.
