While the PS4’s DualShock 4 has been compatible with the PS3 since launch, it only worked using the USB cable. However, a Reddit has discovered that a recent update now allows the controller to be used wirelessly, though not all functionality is available. You can pair the DualShock 4 as a generic bluetooth input device, which means the PS button, vibration and sixaxis detection do not work.
The step by step guide is as follows, but remember to unplug your PS4 beforehand or you may turn it on my accident:
- Connect DS4 with USB cable to PS3 then turn on.
- Go to Accessory settings > Manage Bluetooth Devices
- Start scanning for device
- While scanning, unplug the DualShock 4 from the PS3, and hold the PS & Share buttons on the DS4 until the light-bar starts flashing.
- While the light-bar is flashing, plug the USB cable back into the DualShock 4 and select [Wireless Controller] on the screen.
- Once registration is complete, the DualShock 4 will let you navigate the menus
