Shanwan PS3 controller input delay through bluetooth

[horotony]

Hi guys,
I know this is a common issue, but I still didn't manage to fix it in my recalbox.

I have 4 shanwan dualshock 3 and, even though they are configured in the recalbox UI (they are not vibrating for no reason while connected), I still have an awful input delay in every emulator I use. This is probably related to the BT connection, since I don't have the same issue while connect via USB.

What can I do to fix that? Would a bluetooth adapter connect to the RPpi3 usb slot help?

@horotony if you have a rpi3, yes, a bt adapter helps.

@paradadf is there any other solution?
