How does the tracker communicate its position?

[–] colournoun@beehaw.org 50 points 1 day ago

In general:

The tracker sends out low-energy Bluetooth announcements including its unique id
a nearby iPhone hears those announcements
the iPhone uses its current location
the iPhone sends the tracker id and the location back to Apple via WiFi or cell
Apple notifies the owner of the tracker where the tracker was seen
