Protocol quick explanation?

[nullstalgia]

Heyo, love the project! I want to possibly port a version of it to the ESP32 so I can turn the Base Stations on and off without a PC, but I've been having issues finding reasonable documentation on the protocol. Since you and @tsjost also just got the V1 protocol down (the main one I'm interested in), I'd love to get that in too.

Thanks in advance, and sorry if this is a stupid request.

I mostly referenced https://github.com/risa2000/lhctrl/blob/master/README.md and https://github.com/risa2000/lhctrl/blob/master/PROTOCOL.md

(The readme is saying that you must keep sending pings to keep the lighthouse turned on, but that's incorrect as the 0x1200 command will keep it on indefinitely)

If you didn't see it already, I did a quick overview here: #1 (comment)
Do let me know if you have any specific questions!

What kind of Macro Board? The ESP doesn't have USB (except the newer Silicon which is still being worked on Arduino-wise) And I only have V1 light houses, so I'll let you know once I'm ready to have V2 tested And oof, how did I miss protocol.md

Ah, I wasn't sure if you meant a wireless or wired one. Gotcha.

Awesome, I got a proof of concept working with NRF Connect on my Android phone. Thanks much many for the explanation on # 1, the "little endian" comment makes much more sense now.

Can you guys see if it looks alright? Works for me on my V1 Lighthouses, but I don't have any V2s to test.

Steam doesn't require the BSID [for V1]

It gets the BSID from the headset's/controller's tracking dots when reading the data encoded by the laser spinning inside of the lighthouse.

I was able to get the V1 functionality working with my sketch but I didn't own V2 lighthouses until more recently (about a year ago), and when I tested it, my sketch didn't function as expected. Project fell off the backburner, but maybe now is a good chance to try to get it working.
