If you're on iPhone, you're still beaconing if you turn it off in the swipe down control center, the only way around this is to go into Settings and turn it off there. Also of interest, your iOS BLE "Random" MAC transmits every few seconds and can take up to 48 hours to change. I wrote some software for the Pi that would allow me to enroll a phone when someone was nearby (By RSSI) and then with a directional antenna later in the day, you could confirm presence in a house / building. You can also infer presence of anyone in a house because of this. Oh hey, 2 iPhones in the ex girlfriends apartment, Wonder what's going on in there... Yeah creepy.
