It uses an ESP32 chip combined with nRF24 modules to create noise and send unnecessary packets, effectively jamming these signals within a range of over 30 meters, which can be extended with better antennas or amplifiers. This jammer is intended strictly for educational and security testing purposes to help understand and improve wireless security. It is illegal to use for malicious purposes, so it should be handled responsibly and legally[1][2][3]. https://github.com/EmenstaNougat/ESP32-BlueJammer
