Having kind of the same pb and looking for another alternative to the brute force solution...

Hello, does anyone have any updates about this? Trying to do the same. Wondering if you guys took a different approach or tried to contact Apple directly and how. Thanks.

Hello, same problem here trying to find documentation for both hardware and firmware side. I saw that even some hotels are getting this fonctionnality and we are not able to find any documentation whatsoever. Did you get more information so far? Thanks.
