1 year ago > ### 4. BLE HID PeripheralsWe may support connecting to generic HID devices over BLE (and possibly classic). Users could build on this to add specific mappings for certain devices like popular gaming consoles.

- Does this work with an Xbox controller?
- Does this work with a Stadia controller?
- Does this work with a PS4 controller?
- Is there an / is this the HID Gamepad + Joystick(s) standard, or does there need to be configurable button remapping from device ids sort of like Steam PC?

This is a spot for discussing gamepad connections, split off from https://github.com/pybricks/support/issues/262
