Wii U Pro Controller
The Wii U Pro controller connection procedure is very similar to a Wiimote.
Enable Wiimote Bluetooth searching
Enable Wiimote Bluetooth searching in Device Options. In order to change this option the Titan One device needs to be connected to your computer by the PCPROC side port, through a USB cable.
Connect your compatible Bluetooth dongle to the Titan One input port
To add Bluetooth capability to Titan One device you will need a Bluetooth USB Adapter compliant with 2.1+ EDR standard.
Press the Sync button on the back of your Wii U Pro controller
The LED on the controller should start blinking, meaning the controller is trying to connect with Titan One device. Wait until only one LED stay lighted. If the controller turn off press the sync button again.
Your Wii U Pro controller is connected when the display shows 0 with no dot at the bottom.
