Dear @Mahzaib_Munawar,
the annexed files are the super-simple examples of a working communication on BT between AI2 and an Arduino NANO board fitted with a HC05 or HC06 BT shield.
They work fine (
) on my desk. My testing device is a Lenovo 10" pad featuring Android 10 and an Arduino Nano with a HC06 shield.
I hope you will get help from them.
Obviously it is not mandatory to have an Arduino NANO, it will work with any board (UNO, MEGA,..) with serial interface capability toward an HC0x BT shield (connection schematics below).
Please be aware that on app side it could be necessary to allow the appropriate permissions (scan/connect/geolocalization) as the newer Android versions require. Related to this last matter there are already many topics with examples and solutions by @ABG, @Anke and many others.
Best wishes for your project.
