ESP32-BlueJammer

The ESP32-BlueJammer disrupts various devices using an ESP32 NodeMCU and nRF modules, causing plenty of noise and sending unnecessary packets (DoS).

It interrupts:
audio in speakers, smartphone connections, WiFi, RC Drones (etc.), IoT devices, and much more communicating 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!

operation channels

Bluetooth = 80CH
BLE = 40CH
WiFi = 14CH
RC drones, etc. = 1-125CH

hardware

ESP32 Dev Module (such as ESP32-WROOM-32U)
nRF24L01+PA+LNA (2x)
10UF capacitor (2x) any voltage above 5V

If you're looking to add a battery:

3.7V Li-Ion battery
JST PH 2,0 connector
TP4056 Charging Module
3mm LED (blue)
4,7k Ohm resistor
mini slide switch

To screw the 3D printed case together you must have:

M3X16 screws (2x)
M3 Nuts (2x)

THE 3D printed case fits ONLY a PCB size of 7cm x 5.5cm and you'll need to drill out 2 holes according for the M3 screws to fit through the PCB!

flashing ESP32 via webflasher

I've created a webflasher to make it super easy for you to flash your ESP32 chip with the ESP32-BlueJammer firmware of your choice!

Visit ESP32-BlueJammerFlasher
Connect your ESP32 via a data USB cable
Choose your firmware, chip and connect
Flash the firmware of your choice :D

ESP32-nRF24L01+ pinout

Here are both pinouts for HSPI and VSPI. You need both nRF24L01 modules connected in order to achieve full capability of the device.
