Title: Digix Wifi Sniffer
Post by: JimiSlew on March 02, 2014, 01:13:50 pm

Hi All,

I was wondering if anyone had converted their digix into something that could detect and log open / closed wifi networks?

Thanks,

Jim

If you check out the datasheet linked form the DigiX WiFi wiki page - there is a command to scan for networks, so this should be pretty easy to do.

Hard to realize. For that you need to extend the firmware running on the ATSAM4S8B with access to the MT5931SA (providing WiFi connectivity).
The current libraries give only indirect access to the Wifi subsystem.

You are better of with either an cheap android system, or an device running openwrt. 
With openwrt you can use tools like aircrack-ng or kismet. Kismet is available in a client-server architecture, which allows to use cheap devices without display for sniffing and some other device with a nice screen for showing results.

That seems to be just the API for '3.1.4. STA Setting Page', where you can list available access points to connect to. 
Real scanners search as well for hidden SSID and other stuff. 

At the end, it depends, why you are planning to scan the network:

If your goal is e.g. enforcing company security policies, which prohibit any use of non company WLAN, its important, that you can see also "hidden" networks.
