Does this mean your MAC address isn't visible while on, non-discoverable and connected to a BT device?
- baybal2 7y agoActually Android keep bluetooth on even when UI says off for Google to radiolocate your position.
- rjmunro 7y agoAre you sure? I know they keep some WiFi on, but I didn't think there was much location value in bluetooth signals because most bluetooth devices people use are portable (headphones, cars, etc.)
- baybal2 7y agoActually yes, I did investigate that. Can post a screenshot.
- whatisthiseven 7y agoDid you also disable that setting under the "location" submenu, which explicitly says it works even if bluetooth is off? Not that this is good design, mind you, but if you turned both settings off and still say BT activity, then that is much different.
- baybal2 7y agoIf you do that, it will disable it. Yes, it's a well hidden option deep in the menu.
- gruez 7y agoThat can be turned off.
- mavhc 7y agoI thought that was WiFi
- SwaraLink 7y agoI suspect that in this case the phone is using Bluetooth Low energy “passive scanning”. This means that the phone is listening for advertising devices (eg beacons) but never actually transmitting Bluetooth packets and therefore never actually exposing its Bluetooth address over the air.
- cpncrunch 7y agoIs there a way to make it non-discoverable? I don't see that option on my Nexus 6P running 8.1. You can just turn bluetooth on or off. Or is it just discoverable when you click "pair new device"?
