DualShock 4 On PS3 Wireless Connectivity Now Available If You Follow These Simple Instructions
A recent console update allows you to use the PlayStation 4's DualShock 4 controller wirelessly with the PS3.
The change was first pointed on Reddit, and requires you to follow a few steps. The controller will function as if it's plugged in to the system and will function as a generic controller (no rumble or motion controls), but can even be used to power on the system.
The addition came through a recent PS3 update, but was not something Sony went through any special effort to point out. Prior to the update, only the use of a micro USB cable would allow you to use the DS4 on the last generation system.
Eurogamer has helpfully listed the steps needed to make the DS4 work on PS3, which are not too difficult or time-intensive. You'll need to download the update, of course, and the plug the controller in to the PS3.
Following that, you'll need to register your DS4 as a Bluetooth device with the system, which is done by going to the 'Manage Bluetooth Devices' option in the 'Accessory Settings' menu. Scan for a Bluetooth device, unplug the DS4 from the console, and then hold down the PS and Share buttons. Once it finds the DS4, plug it back in and select 'Wireless Controller'--it should work after that if you've done it correctly!
It might not be a fully functional controller (whether the loss of some features is worth being able to use the superior device is up to you), but it's a nice addition that will hopefully lead to full PS3 support.
