That's great, thanks!

Maybe you also want to have a look at the userspace side and talk to Mark Greer (on cc). He recently said, that he is supposed to be taking over maintenance for the neard daemon (see this thread: [1]) which currently looks like it's close to being dead (no release for several years, etc.).

I don't know much about the NFC stack and if/how people use it, but without reliable and maintained userspace tooling, the whole thing seems of little use in the long run. Qt has already dropped their neard support for Qt 6 [2], which basically means the mainline NFC stack won't be supported anymore in one of the most common application frameworks for IoT/embedded.
