I tryed to connect a Wii U Pro Controller to my PC with a Bluetooth dongle. But the Connection isn´t stable and disrupts after 3 seconds.....
So installed the Toshiba Stack driver like in the Guide on the Win U Pro site described it.
After the installation of the Driver i have the Bluetooth symbol in my Tray. When i try to connect my Win U pro Controller it finds it but it has problems to register it.
i need to constantly press the Sync button on my Wii u Pro Controller to get it registered. After that it is connected it disconnects after 3 seconds and it just connects if i press the red sync button on the controller again for 2-3 seconds.
So it shows me the Device (Nintendo RVL-CNT-01-UC) in the Bluetooth Configuration but it just doesn´t connects longer than 3 seconds....
Without the Toshiba Stack, you should use the sync button in WiinUPro or WiinUSoft. This will pair the controller with your PC which should prevent the quick disconnect. Afterwards, to disconnect the controller, hold its power button. To reconnect it again, just press a face button on the controller.
Another option is to pair the controller to the Wii U again. That typically helps as well.
