@dankcushions said in Random Button Presses When Using Wii U Pro Controller:
if the issue is with the pi's onboard bluetooth, then the only people who could fix it are those supporting the linux drivers/firmware, not retropie.
This thread seems to suggest that some controllers don't filter their signals sufficiently and the Pi doesn't do that either. USB and wireless adapters tend to filter these micro signals, thereby fixing the problem, as does adding capacitors to the faulty controllers (final confirmation).
The question is, can it be considered an error on the part of the Pi that it's "too sensitive", if the actual fault lies with the controllers.
