Your CySmart scan parameters configuration looks fine. I have tested it and it worked for me.
Only the device added in whitelist came up while scanning.
Please note that once you close Cysmart the setting will not be retained.
I've realized that when I see other devices, the MAC address are always 'random' and not 'public'. I'm assuming that whitelist is not applying to random MAC addresses. Is there a way to block out the devices that have a random MAC address?
