Just under a month ago we wrote about Bluetooth RSSI, Social Distancing and Contact Tracing and how the UK Government was going their own way:
Google and Apple have implemented a new API to allow contact tracing apps to work well on iOS and Android. Some Governments, such as ours in the UK, have currently gone their own way with apps that use existing APIs. Such aforementioned restrictions stop smartphones seeing each other thus severely reducing their effectiveness. The apps won’t work properly and will provide very limited benefit.
We are not surprised that Sky News is reporting that there has now been a U-turn.
To all governments trying to use the standard iOS and Android APIs to measure social distancing and perform contact tracing: You are wasting important time.
