After BLE is connected, retroactive pairing failed due to no cache is found. 05-27 18:24:21.381 I NearbyDiscovery: [trigger-id=Paed20819D34, feature-id=Repa] RetroactivePairManager: Skip, some info is null, mac=XX:XX:XX:XX:00:0D, remainingTime=0, ble-mac=XX:XX:XX:XX:1C:2D, model-id=99F751, bleCache=NONE [CONTEXT service_id=265 ] It may because the model-id 99f751 is filtered by spoofing detected. ModelIdScanTriggerStats ** last-seen-ms-ago= 95982, first-seen-ms-ago= 107254, count= 90, model-id=99f751, NotDownloadedYet, mac=XX:XX:XX:XX:1C:2D, min-distance= 0.07, max-distance= 1.00, result=SPOOFING_DETECTED Since the model-id 99f751 has still not approved in the device console yet, could you go to Settings > Google > All services > Devices and enable Include debug results (requires to enable developer mode first) Then, test again to see if the device can detect the advertisement correctly. Thanks!
