Detect deauthentication frames using an ESP8266
Support me and my projects on Patreon!
If the ESP8266 detects deauthentication or disassociation frames it will turn on its LED. That's all ¯\ (ツ)/¯.
So this is a good and cheap way to detect a Wi-Fi deauthentication attack.
You will only need to follow one of the installation methods!
#define channel 1 //the channel it should scan on (1-14) #define channelHopping true //scan on all channels #define maxChannel 13 //US = 11, EU = 13, Japan = 14 #define ledPin 2 //led pin ( 2 = built-in LED) #define inverted true // invert HIGH/LOW for the LED #define packetRate 3 //min. packets before it gets recognized as an attack #define scanTime 500 //scan time per channel in ms
