Dynamic BLE addressing issue #132

Closed Semper-Viventem closed 1 year ago

How do you determine the fact that the device you found in the current scan is the same device that you found several scans ago? I can see that you match beacons by the device address, but SmartTags and AirTags use dynamic addressing and change addresses each 15-30 minutes.
