ESP32-BlueJammer - by @emensta

The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts various devices using an ESP32 and nRF24 modules, causing plenty of noise and sending unnecessary packets (DoS). It interrupts: The whole 2.4GHz broadband! Everything that works on 2.4GHz is being interfered, like: audio in speakers being transmitted over bluetooth, microphones on 2.4GHz, smartphone connections, WiFi, RC Drones (etc.), IoT devices, smart gadgets, wireless keyboard & mouse, just anything on 2.4GHz! Ideal for controlled disruption and security testing. Based on 2,4GHz communication. It has a big range (over 30Meters+ - may vary on your antenna and hardware setup!) on newest Bluetooth versions with casual 2.4GHz antennas, you can easily increase this aswell by taking some simple "bigger" router antennas. An amplifier (2.4GHz) may be an good option too! Remember that jamming is illegal and should not be used with malicious intent! This is strictly for educational purposes only!
