Add support for Nreal Light and Rokid Air

[iraqigeek]

Hi,
The current API supports only the Air. What would you need to add support for the Light and Rokid Air? Both use a very similar HID magic packet to switch from 2D to SBS 3D mode.

I have a USB 2.0 sniffer. I have some dumps that I could share of you want. They were taken with (an old) Lecroy USB Analyzer, and require Lecroy's USB Protocol suite

I'm not able to record new ones as Nebula refuses to open now asking me to update, but Nreal hasn't made Nebula available in the Netherlands :\ I don't currently have the Rokids with me. I'm not sure if I have any dumps from them either.

The Light's HID device VID is 0x0486 and the PID is 0x573C.

The Rokid's HID VID is 0x04D2 and the PID is 0x162F.

Hello! I would love to take a look at whatever you have. Me and a few others have been working on this for a few months now. We have done a lot of reverse engineering and packet captures but with a dedicated tool you might have some easier data to work with. As for support for the lights, this can be done, I think we have some idea of the commands but I don't have access to a pair so it's hard to develop for it. Same pretty much goes for the rokid, if you have the commands and can figure out the HID protocol that too could also be added. But it would be hard to calibrate them without having like the lights. I would still be willing to try but we are mainly trying to get the sensor fusion stable on the Airs first as most of us have them. Thanks for reaching out. Matt

I have two pairs of light (dev kits) so I am happy to help out. I'm also a programmer (although mostly web) but not afraid to get into lower level code (I've picked up a bit of Zig recently) if that helps too. If I have some guidance on what to do, I can help out.

Edit: I should also add - I run Windows 11 with WSL (subsystem Linux - Ubuntu) and I have a Macbook Pro. I also have an iPad Air, an older iPhone, some android phones & tablets. Lots of devices for me to test on/with.

The Light and the Air share the same sensor fusion code in Nebula. Whatever works on one will work on the other :)

We are working on improving some of the code, we will try and add support for the lights in the next version
