Hi this is first post of 2015!!
I'm new at this and i don't speak english very highly, it will be difficult, but let's go:
I wanna get the mac addresses of all devices, notebooks, smartphones, etc, in range of my wifi network who are not connected, in other words, who is "viewing" the wifi network i want the mac.
It's possible?
And if yes how i do?

its not possible

Those who listen do not transmit. Have you got it?

All who see the network I want to get the mac address.
Even if my phone is with the wifi on but not connected in my pocket.

This is not possible?
