I did a few tests with my Ruuvitag and different phones. Not a single phone was able to detect the Ruuvitag without additional application. I tried four different phones, Android and iOS.
I start to feel that I have a major misunderstanding about how a Ruuvitag is supposed to work. In my understanding, the Ruuvitag should show up on your phone as a notification, as long as you a) are close by, b) have location services turned on, c) have Bluetooth turned on. I thought that there are no additional requirements. Is this correct? If so why is it not shown on any of the phones that I tried?
All help is very much appreciated. Thanks!
