On the iPhone it just goes to sleep. This is a killer. But it's not the end of it. Bluetooth can't measure distance well, it's totally not in it's design. Every phone model is different, I think including software version. So there are databases of phone models to try and fix this. But it's still far from perfect since it's still not in the Bluetooth design. Measuring time of exposure is hard with Bluetooth. Now Apple and Android released frameworks to try and fix these issues. But governments had already invested in the old solution and it's not clear if the new framework will fix much. To do what they want to do with Bluetooth would be pretty amazing. It's basically Geo Location using beacons using existing phone tech. That's fucking cool, yet for some reason it's never been done before this, Covid solves all technological issues it seems? GPS tracking works really well. You will also know where. So you can see if it was inside, outside, walls between them, all things vague Bluetooth apps can't do. Lot's of context with GPS. So, what do we think governments will do when Bluetooth has been shown not to work, but this privacy invading app works really well, which it should.
