You need USB OTG adapter to connect your PS3 controller to STS for initial configuration. First, turn on your Bluetooth, connect your PS3 controller using the USB OTG adapter, and STS will initiated pairing. Once paired, you can disconnect the cable, and PS3 controller will be connected wirelessly via Bluetooth. Pairing with USB cable is one time only. Next time you connect, it will connect wirelessly unless you lost the pairing.
