8BitDo Ultimate 2C Works on the Wrong Platform

Ultimate 2C Bluetooth and Ultimate 2C Wireless are different products with different host and connection modes.

Why this happens

The shared 2C family name hides a Bluetooth-versus-Wireless hardware split.

What to check

1. Read the full model name and hardware label.
2. Compare that exact model's Switch, Windows, and Android support on 8BitDo's product page.
3. Apply only the firmware and mode documented for your model.
