Info

The ESP32 is able to filter captured WiFi traffic to display and harvest AP beacons sent from surrounding WiFi Access Points.

Once a packet is captured, it is checked for the identifying beacon byte.

if ((snifferPacket->payload[0] == 0x80) && (display_obj.display_buffer->size() == 0))

For each beacon captured, the following information will be displayed on screen:

Source MAC
Source ESSID

All beacons will be saved to an attached SD card in a PCAP file.

This function can be exited by touching the screen. Once exited, the user will be sent back to the menu.
