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!

Does this work with Raspberry Pi 4 or Raspberry Pi Zero 2 W? Unfortunately I don't have Pi Zero W lying around :(

Any SbC with OTG support should work, so both Zero W and Zero 2 W should be compatible (I tested it with RPi Zero 2 W—I will update the docs).

I can't find definitive information for RPi 4 though, I see some references to using it online but the spec here does not seem to mention USB host or OTG
