Wireless keyboards. What a concept! I've got a few of them and they are usually designed to work over either Bluetooth Classic or Bluetooth Low Energy (BLE). Not every computer or microcontroller can connect with them, but a Pico W or Pico 2 W can, and just costs a few dollars...
And that very same Pico can bridge the wireless keyboard messages via USB HID to a host computer or microcontroller. This way, any computer or device with USB keyboard support can now connect to a Bluetooth Wireless keyboard, without needing BT support. Instant wireless bridge!
This guide will show you how to build a versatile, cheap, small keyboard bridge for all the Blueteeth!
