This isn't then a very good solution. So if the point is not to leak all
known SSIDs all the time while scanning, that needs to be addressed for
all scans. I'd still expect hidden networks to be scanned if they did
not turn up in the passive WiFi scan. Else there is a subset of networks
that can be connected only once; having the user to notice the
relationship between full privacy and hidden WiFi networks will fail
very reliably...
So the idea is not to reveal the WiFi networks used by doing active
scans where active scans are not strictly necessary? By doing active
scan only for known hidden networks, yes, the device reveals itself -
but that is the cost of using hidden networks, right?
Cheers,
