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.<p>> Provides a number of approaches to workaround the ‘iOS detection in the background’ bug in iOS to a point where detection and continuity is superior to existing protocols<p>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.<p>[1] <a href="https://vmware.github.io/herald/specs/protocol" rel="nofollow">https://vmware.github.io/herald/specs/protocol</a>
