Hi Giuliomoro, I have several questions about how to connect Bela mini to Unity. I'm a beginner, so if some questions I'm asking may confused you, wish to have your understanding 
1. What is the best way to connect Bela to Unity. specifically, there is a distant sensor on Bela mini, the sensing value control the animation that created with Unity. In turn, the different animation (different motion activity from a character) will influence the haptic motor connected on Bela board as output. In a word, how to send data back and forth between unity and bela board.
2. Would you please introduce me some online course/materials, that you think I can start to learn.
looking forward to having your response. thank you so much in advance.

what's with the thread hijacking?

Does Unity take MIDI ? In that case, MIDI is probably the best way to communicate to/from it. If you use the MIDI device hw:1,0,0 from Bela, that will send/receive to/from the USB MIDI interface that shows up on the host when you connect your board. If you are using Pd, have a look at the example PureData/midi-cv-midi .

Hi Giuliomoro,
I am very sorry for hijacking the thread. I have no idea where to post my questions, and add a new theme tag. Thank you for adding the new tag.

a bit late maybe, but as a unity dev im researching if bela is the hardware tool i need... there are a lot of free assets written for midi intergration by Keijeiro, https://github.com/keijiro?tab=repositories&q=midi, using osc might be a good option as well, depending on your application, https://github.com/keijiro?tab=repositories&q=osc, and there are some paid assets as well... https://assetstore.unity.com/?q=midi

and what is an interesting workflow, is that its possible to "embed" libPd inside unity, which probably makes the whole testing, debugging of communication between bela & unity much easier, as on both sides puredata can be used... its a playlist of several videos, showing various kinds of implementation and communication between unity and pd
