title: Find MAC Addresses of devices in range of Wifi router
body: <p>I'm currently working on a raspberry pi project that would require the wifi dongle (Realtek RTL8188CUS) to obtain the MAC addresses of nearby devices that have not connected to it. I had originally thought of doing this through tcpdump but those logs only seem to display the info of devices connected to the wifi network. So what I'm trying to figure out is: how to receive a log or list of MAC addresses within range of the network but are not connected to it.</p>
