Using a bluetooth gamepad controller with iOS/Android

Hello,
I would like to know how I could use a bluetooth gamepad controller such as PS4 Dualshock, PS3, Xbox controller with a Unity game compiled for iOS or Android.
It seems it’s not compatible with Low Energy Bluetooth.
So what I can do / buy to make it work ?

Regards

for bluetooth low energy you need to built in something in your project if you buy a regualer bluetooth controller than it should work with the same axis as on pc.(for most controllers) ipega 9023 works fine
