# joycontrol
|
|
Emulate Nintendo Switch Controllers over Bluetooth.
|
|
|
|
Tested on Ubuntu 19.10, and with Raspberry Pi 3B+ and 4B Raspbian GNU/Linux 10 (buster)
|
|
|
|
## Features
|
|
Emulation of JOYCON_R, JOYCON_L and PRO_CONTROLLER. Able to send:
|
|
- button commands
|
|
- stick state
|
|
- ~~nfc data~~ (removed, see [#80](https://github.com/mart1nro/joycontrol/issues/80))
|
|
|
|
## Installation
|
|
- Install dependencies
|
|
|
|
Ubuntu: Install the `dbus-python` and `libhidapi-hidraw0` packages
|
|
```bash
|
|
sudo apt install python3-dbus libhidapi-hidraw0
|
|
```
|
|
|
|
Arch Linux Derivatives: Install the `hidapi` and `bluez-utils-compat`(AUR) packages
|
|
|
|
|
|
- Clone the repository and install the joycontrol package to get missing dependencies (Note: Controller script needs super user rights, so python packages must be installed as root). In the joycontrol folder run:
|
|
```bash
|
|
sudo pip3 install .
|
|
```
|
|
- Consider to disable the bluez "input" plugin, see [#8](https://github.com/mart1nro/joycontrol/issues/8)
|
|
|
|
## Command line interface example
|
|
- Run the script
|
|
```bash
|
|
sudo python3 run_controller_cli.py PRO_CONTROLLER
|
|
```
|
|
This will create a PRO_CONTROLLER instance waiting for the Switch to connect.
|
|
|
|
- Open the "Change Grip/Order" menu of the Switch
|
|
|
|
The Switch only pairs with new controllers in the "Change Grip/Order" menu.
|
|
|
|
Note: If you already connected an emulated controller once, you can use the reconnect option of the script (-r "\<Switch Bluetooth Mac address>").
|
|
This does not require the "Change Grip/Order" menu to be opened. You can find out a paired mac address using the "bluetoothctl" system command.
|
|
|
|
- After connecting, a command line interface is opened. Note: Press \<enter> if you don't see a prompt.
|
|
|
|
Call "help" to see a list of available commands.
|
|
|
|
- If you call "test_buttons", the emulated controller automatically navigates to the "Test Controller Buttons" menu.
|
|
|
|
|
|
## Issues
|
|
- Some bluetooth adapters seem to cause disconnects for reasons unknown, try to use an usb adapter instead
|
|
- Incompatibility with Bluetooth "input" plugin requires a bluetooth restart, see [#8](https://github.com/mart1nro/joycontrol/issues/8)
|
|
- It seems like the Switch is slower processing incoming messages while in the "Change Grip/Order" menu.
|
|
This causes flooding of packets and makes pairing somewhat inconsistent.
|
|
Not sure yet what exactly a real controller does to prevent that.
|
|
A workaround is to use the reconnect option after a controller was paired once, so that
|
|
opening of the "Change Grip/Order" menu is not required.
