Very interesting how they made this work on iOS, given so many failed (before the Apple/Google protocol was released). A lot of the design documentation references the UK market, I wonder if VMWare were asked/volunteered to help with the NHSX app that tried to ignore the Apple/Google "blessed" approach.

The technical details on the protocol (seperate from the "payload" which is contact tracing specific data) are here[1], and the iOS library here[2]. I would be interested if anyone else has verified these claims.

There is a bit of evidence that it _doesn't_ work on iOS, at least not as well as advertised.

Yes. VMWare were one of the lead contractors on the original UK app, but are no longer on the project.
