ESP8266 packet injection/sniffer example

Warning! This example runs with a particular SDK build that is now integrated into this project. Future versions of the esp_iot_sdk removed the ability to send wifi control frames with wifi_send_pkt_freedom.

This example project utilizes sniffer capabilities of ESP8266 to perform deauth attack. The communication between the victim and access point (AP) is traced by wifi_set_promiscuous_rx_cb while packet injection is performed by wifi_send_pkt_freedom. To use the example adjust the Makefile and change MAC addresses in user/user_main.c.
