Question: How to access wiimote input data [DSU Client] to make another script

[martinprad0]

I have built linuxmotehook2 on my laptop and want to access the wiimote controller input from the DSU Client. My goal is to write a bash script that makes the wiimote pointer my desktop's mouse and maps the wiimote buttons to other keys.

The question is how can I access the data in localhost:26760 to make this happen.

I'm not very familiar with the GitHub discussion system. With a second though, I believe that the issues section was not the correct place to start this question. I'm really sorry.

I'd recommend looking into using xwiimote library directly instead of relying on this project as middleware:

• linuxmotehook2 does not expose wiimote's IR pointer if that's what you want to use - only motion/buttons.
• xwiimote library is likely quite a bit easier to use than DSU protocol. Neither is (reasonably) usable from bash, though - which is just a poor fit for this task overall.
• To elaborate on the previous point - xwiimote provides an interface that's purposefully easy to use; with DSU protocol you'll have to encode and parse binary packets yourself.

I'd suggest either using C/C++ interface directly, using this project's Vala bindings, or Lua bindings I wrote a while ago (plus probably lua-posix for file descriptor polling). There are also ancient official bindings for Python 2, but you shouldn't use them for obvious reasons.

Thank you! I'll investigate more.

I think that for a personal project like this using Lua bindings would be the best choice; while somewhat harder to redistribute it's much quicker to develop for. Otherwise, I'd go with Vala (which linuxmotehook2 is written in).

Feel free to ask further questions!

It may be worth noting that there's an old X11 module that allows to use wiimote like you've described. Unfortunately, one has to edit X config to turn it off/on and I've found it to be very crash-prone, so can't recommend using it in practice.
