⚠️ Important: Can't use buttons on Joy-Con to navigate the UI in JD 2016-2019 (you'll have to use controllers/keyboard). See #6.

How does it work?

It pretends to be the Just Dance Controller app, sends movements of the Joy-Con to your game console.

Tested on

MacOS Catalina 10.15 with TP-Link Bluetooth 4.0 Nano USB Adapter UB400.
Raspberry Pi Zero 2 W (Bulleye, kernel 5.15) with MPOW BH519A Bluetooth 5.1 USB Adapter. Tested with 2 Joy-Cons and it worked just fine.

Requirements

PC/Mac/Linux with bluetooth support.
Python 3.7+ and pip installed.
1 to 6 Joy-Cons.
It's RECOMMENDED to:
- Use a Bluetooth dongle, because built-in Bluetooth sucks (or you will get disconnected constantly while playing). Make sure you buy a dongle with game controllers support, not just for audio devices. Not all dongles support Mac/Linux, so remember to check compatibility before buying.
- Use a Nintendo Switch to update Joy-Con to the latest firmware & calibate its motion sensors. Ask your friends or bring it to the game shop if you don't have one.

Installation

Download the latest version and extract it into a folder.
Open that folder in Terminal/Command Prompt, then run this command:

pip3 install -r requirements.txt

Extra steps for Linux users

Click to expand!

Linux users may need to use hid instead of hidapi (not sure why hidapi couldn't find Joy-Cons on Linux).

pip3 uninstall hidapi

sudo apt install libhidapi-dev
pip3 install hid

Create a new udev rule file at /etc/udev/rules.d/50-nintendo-switch.rules (Source)

# Switch Joy-con (L) (Bluetooth only)
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", KERNELS=="0005:057E:2006.*", MODE="0666"

# Switch Joy-con (R) (Bluetooth only)
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", KERNELS=="0005:057E:2007.*", MODE="0666"

# Switch Pro controller (USB and Bluetooth)
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="2009", MODE="0666"
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", KERNELS=="0005:057E:2009.*", MODE="0666"

# Switch Joy-con charging grip (USB only)
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="200e", MODE="0666"

Reload udev rules:

sudo udevadm control --reload-rules
sudo udevadm trigger

Install dkms-hid-nintendo (Joy-Con driver) if you're running Linux kernel older than 5.16.

Usage

Open the phone pairing screen on Just Dance.
Connect your PC/Mac/Linux to the same Wi-Fi or LAN network as your game console. For Stadia you just need to connect to the internet.
Run this command:
```
python3 dance.py
```
or
```
python dance.py
```
Open http://localhost:32623 (not https://...) in a web browser (32623 = DANCE). You can also open JoyDance on another device (connected to the same network) with this link: http://[JOYDANCE_DEVICE_IP]:32623 (for example: http://192.168.1.100:32623).
Turn on Bluetooth and pair with Joy-Con by holding down the SYNC button until the light move up and down. Press the "Refresh" button until your Joy-Con shows up.
