switch-pro-xy

A bluetooth proxy between Switch and Pro Controller.

Requirements

sudo apt install libdbus-1-dev

Disable plugins in BlueZ(This step may be performed automatically at runtime in the future, see here)

Add --compat --noplugin=* after ExecStart=/usr/lib/bluetooth/bluetoothd in /lib/systemd/system/bluetooth.service

Run

sudo systemctl daemon-reload
sudo systemctl restart bluetooth

Get bluetooth address of Pro Controller and Switch

Replace [CONTROLLER_ADDR] and [SWITCH_ADDR] with your bluetooth addresses:

git clone https://github.com/spacemeowx2/switch-pro-xy.git
cd switch-pro-xy
cargo build
cargo run -- [CONTROLLER_ADDR] [SWITCH_ADDR]

When the program starts, press and hold the small, circular
button on the back of the Pro Controller (near the USB-C input) until the
player lights begin Flashing.
Once the program prints "Got Connection" and then "Waiting for Switch to
connect...", start up your Switch and navigate to the "Pair/Change Grip" menu.
Switch should automatically connect to your PC.
After a few seconds, when you see "About to start forwarding packets. Please
close the menu in 5s", close the Switch menu.
When the program prints "Start forwarding packets", you are ready to go.

In Splatoon3, when you enter the Equip menu, the controller will be disconnected.
