As evident from the below log snippet, once the remote device is disconnected, the host will start a Passive scan. The filter policy is set to "Accept all advertisement" as the previously paired device in the White List (Designer Mouse) has random address: < HCI Command: Disconnect (0x01|0x0006) plen 3 #159 [hci0] 19.853664 Handle: 3585 Reason: Remote User Terminated Connection (0x13) > HCI Event: Command Status (0x0f) plen 4 #160 [hci0] 19.855749 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 #161 [hci0] 19.903759 Status: Success (0x00) Handle: 3585 Reason: Connection Terminated By Local Host (0x16) @ MGMT Event: Command Complete (0x0001) plen 10 {0x0001} [hci0] 19.903829 Disconnect (0x0014) plen 7 Status: Success (0x00) LE Address: DF:29:ED:8F:82:95 (Static) @ MGMT Event: Device Disconnected (0x000c) plen 8 {0x0003} [hci0] 19.903852 LE Address: DF:29:ED:8F:82:95 (Static) Reason: Connection terminated by local host (0x02) @ MGMT Event: Device Disconnected (0x000c) plen 8 {0x0002} [hci0] 19.903852 LE Address: DF:29:ED:8F:82:95 (Static) Reason: Connection terminated by local host (0x02) < HCI Command: LE Set Scan Parame..
