check devices not connected

asierfd opened this issue · comments

Amazing work!
I have a question that I´ve been trying to solve but unsucessfully.
Is there any way to check devices around me, but not connected to any wifi?

Thanks a lot

Thanks!

If the client (station) is doing active scanning by sending out probe requests, you should in principle be able to pick those up. But I don't know if the current code would catch those. If the client only does passive scanning, I do not see any way of detecting it (since it would not be sending anything).

You can read much more about probe requests here:
