Plotting live graph on mobile app using android Application

I'm developing Live application for Plotting real time-temperature value on an android application using Android Studio. I have done mobile Bluetooth Socket connection. but problem arriving in Arduino code. I don't Understand how can i develop Arduino Bluetooth code.

I don't Understand how can i develop Arduino Bluetooth code.

There are hundreds, probably thousands, of examples of sending data from the Arduino via Bluetooth but without a basic understanding of programming the Arduino you will quickly become bogged down

Start by looking at the examples in the Arduino IDE.

Which temperature sensor do you intends to use ?

Which Arduino do you have? Which Bluetooth module is attached to the mystery Arduino? How is the module connected (wiring diagram, please)?
