go-hidproxy

Proxies Bluetooth keyboards and mouse as HID devices (eg. with Raspberry Zero Pi W)

Build

Requires libudev-dev package (sudo apt install libudev-dev).

Build with Go 1.11+:

go get github.com/rosmo/go-hidproxy/cmd/go-hidproxy
sudo cp ~/go/bin/go-hidproxy /usr/sbin/go-hidproxy

Install

• Build the binary
• Copy binary to /usr/sbin/go-hidproxy
• Install systemd unit file to /etc/systemd/system
• Reload daemons: sudo systemctl daemon-reload
• Enable hidproxy: sudo systemctl enable hidproxy
• (Optionally) Start hidproxy: sudo systemctl start hidproxy

Raspberry Pi Zero W setup

I used a pretty standard Raspbian image:

Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 10 (buster)
Release:        10
Codename:       buster

You'll need to setup /boot/config.txt with:

dtoverlay=dwc2

In /etc/modules you should have:

dwc2
libcomposite
evdev

Pair Bluetooth keyboard/mouse

One time pairing:

# sudo bluetoothctl
> discoverable on
> pairable on
> agent NoInputNoOutput
> default-agent
> scan on
> pair aa:bb:cc:dd:ee:ff
> connect aa:bb:cc:dd:ee:ff
> trust aa:bb:cc:dd:ee:ff

Tested with

• TEX Shinobi keyboard / Trackpoint combo
• Razer Deathadder V2 Pro
