bluetooth - Can you uniquely identify a BLE MAC address in Android 5.0? -


in android 5.0, ble doesn't use static mac addresses anymore, macs change after intervals, using method called irk , public key cryptography.

is possible uniquely identify android phone in way can not spoofed user of phone, or has become impossible unless other side co-operates?

no, not possible. that's whole idea of using irks: only bonded devices can identify after address changes. not possess irk (because have not bonded), appear new device (hence privacy).
