Interesting read. I wonder where OP got the specs for the device itself, i.E. what it expects in terms of data and what the response (interrupt) values mean?
To my surprise, Nanoleaf tech support responded to me within 4 hours, with a full description of the protocol that’s used both by the Desk Dock as well as their RGB strips. The docs mostly confirmed what I had already discovered independently, but there were a couple of other minor features as well (like power and brightness management) that I did not know about, which was helpful.
Combo of investigating and a foot up from the manufacturer.
When I’ve done this in the past for game controllers I’ve not received such an emphatic response (other than when I was working for the vendor).
Did get some via FOI for a few other products though.
Yeah, props to the Nanoleaf team for helping the author out. Win-win. The author says at the end that they intend on sharing it around more once it has more polish, so I hope they upstream it properly and demonstrate to Nanoleaf that helping out volunteers helps their product reach more customers. (I know it’s iffy to suggest it’s ok to neglect Linux and let us sort it out ourselves, but if we get open-source drivers in the process with the help of the company, I think that’s a net win)
Over the past few posts I’ve set up a Windows VM with USB passthrough, and attempted to reverse-engineer the official drivers, As I was doing that, I also thought I’d message the vendor and ask them if they could share any specifications or docs regarding their protocol. To my surprise, Nanoleaf tech support responded to me within 4 hours, with a full description of the protocol that’s used both by the Desk Dock as well as their RGB strips.
