The Pico Bluetooth Keyboard Bridge is designed to search for a Bluetooth Classic keyboard to connect to first, then search for a BLE keyboard. If no connection is made, it repeats this cycle.

To use it:

• Plug it into the target computer (or microcontroller with USB HID keyboard host) and put the keyboard into pairing mode
• The Pico's LED will blink slowly while it scans for a device
• LED blinks rapidly when a device is found
• Press a key on your keyboard to connect
• LED turns on stead solid while connected
• LED blinks once per keypress while in use
• To re-scan for a different keyboard, press the Pico's BOOT button
