Distributed-Wifi-Capability-Collector(DWCC)

This project is designed to passively collect WIFI(802.11) management frames from inexpensive sensors distruted to see what features and specifications your WIFI clients support.

The plan is to collect pcaps then analyze them extracting the relevant data on the sensor. Then sending it to a central database.

Got ideas from https://github.com/Geovation/wifispy and https://github.com/roobixx/harbinger

Status LEDs

The follwing LEDs have been tested with Raspberry Pi 3. To use the status LEDs you must make sure that the VAR "iamapi" is set to 1

• Gpin 6 is on when sniffer is running
• Gpin 13 is on when the sensor can ping google.com
• Pin 1 will come on when the device boots

Wiring LEDs on PI

This will be updated at a later time.
