Firstly, I am making a game and I want to connect my PS2 Controller to my Android phone with bluetooth for a game I am making with Unity.

Is it possible to connect both of them ?

With my lowly research, i came to know that the protocols are old and this functionality isn’t supported.

Else I have to root my phone, which I don’t want to.

Suggestions I need:

1. Any third-party app that would act as a medium which would re-direct the inputs to the game.
2. Any modules or implementation that I could make to make this work around.
