A node.js package that enables communication with the HaritoraX FBT trackers to read/write data to the trackers. No HaritoraConfigurator software needed (mostly)!
Check out the Haritora-GX(6/2) proof-of-concept repository here: https://github.com/JovannMC/haritora-gx-poc
- A new proof-of-concept repo will be made soon, including all the information I've found about the trackers while developing this package!
npm install haritorax-interpreter
Will write actual documentation at some point, for now refer to the source code, examples, and JSDoc comments. You may also see how it's used in SlimeTora!
For Linux users, you (or your users) need to do some setup depending on the connection mode so the package can communicate with the trackers:
- Run the following commands in your terminal:
sudo usermod -a -G dialout $USERsudo usermod -a -G tty $USERsudo usermod -a -G uucp $USER(for Arch-based distros)
- Restart your computer
See https://github.com/chrvadala/node-ble/tree/main?tab=readme-ov-file#provide-permissions for more info
- Create a new dbus rule (e.g.
/etc/dbus-1/system.d/node-ble.conf) - Insert the following as the contents, changing
%userid%with your user
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"

}, 10000)- SlimeTora - A program that connects any of the HaritoraX trackers to the SlimeVR server, supporting Bluetooth (classic), Bluetooth (low energy), and the GX(6/2) communication dongles for all the HaritoraX tracker models!
