Probe Request Sniff

Probe Request Sniff

The ESP32 is able to filter captured WiFi traffic to display and harvest probe request sent from surrounding WiFi clients against any network. Once a packet is captured, it is checked for the identifying probe request byte. ```C++ if ((snifferPacket->payload[0] == 0x40) && (display_obj.display_buffer->size() == 0)) ```

For each probe request captured, the following information is displayed on the screen:

• Source MAC
• Destination ESSID

All probe requests 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.
