Hi HN! I built Bluetooth USB Peripheral Relay, a tool that lets Bluetooth devices (like keyboards and mice) connect to USB-only hosts using a Raspberry Pi Zero W.

Why? My friend needed a way to use his Bluetooth mouse and keyboard on a PC with Bluetooth disabled due to policy restrictions. This tool acts as a bridge, relaying Bluetooth input over USB. It also lets you use Bluetooth peripherals with older devices that only support USB input.

Tech: Written in Go, optimized for Raspberry Pi Zero W.

I love HN’s community and often lurk here—I’m hoping this project is useful or at least sparks some interesting discussions. Feedback and contributions are welcome!

This solves a huge annoyance I've had: swap a Bluetooth keyboard/mouse between multiple laptops, without manually un0paring / re-pairing. I have a personal "hot desk" at home. I want to be able to plug in any laptop to the large monitor, and have the wireless keyboard/mouse on that desk instantly work. And when I leave the desk with my laptop, I don't want that keyboard/mouse connected anymore.

This has been impossible so far, because even USB bluetooth dongles still require each host computer to pair (and un-pair) with the keyboard/mouse.

I am going to try your solution, and I will plug the USB input into the large monitor on my desk. Then any laptop that plugs into that monitor should have access to the wireless keyboard/mouse. Thank you for creating and sharing this!

I had a similar problem but dual booting windows/linux. Though I managed to share the link keys with some registry hacks in the end.
