ESP32-BlueJammer

The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts devices using an ESP32 and nRF24 modules, causing plenty of noise and sending unnecessary packets (DoS).

It interrupts:
The whole 2.4GHz broadband! E that works on 2.4GHz is being interfered, like:
audio in speakers being transmitted o, 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 (o+ - may vary on your antenna and hardware setup!) on newest Bluetooth with casual 2.4GHz antennas, you can easily increase this as well by taking some simple "bigger" router antennas.
An amplifier (2.4GHz) may be a good option too!

Remember that jamming is illegal and should not be used with malicious intent!

PCB's with ESP32 and RF-module capability

ESP32-RF DIY-PCB:
This PCB can fit an ESP32-wroom-32U/E DevKitC and 2 nRF-modules, along with an 0.96" I2C OLED, LEDs and switches.
*Remember: It is not intended for illegal use!*
For this one, all you need is listed below:

Required:

ESP32 De (Recommended: ESP32-32U CP2102, any ESP32 should work as long as it has the needed pins, 38P required!)

nRF24L01+PA+LNA (2x)

10-100uF Capacitor (2x) (any above 5V)

0.96" OLED Display I2C

Slide Switch (2x)

LEDs: 3mm LED box

Resistor kit

R1 = 1kOhm

R2, R3, R5, R7 = 47kOhm

R4, R6 = 100kOhm

Additional:

TP4056 Charging Module (Micro-USB/Type-C)

JST PH 2.0 Connector

3.7 Battery

3rd Antenna: IPEX to SMA-F pigtail**

PRE-SOLDERED: "The Blue ESP"
This is an ESP32 with RF-module breakouts (nRF24/CC1101 etc.) for experimenting.
*Remember: It is not intended for illegal use, neither for my project!*

Required:

nRF24L01+PA+LNA (2x)

Why do you need to get the nRF24's? -> the pinout can be used to connect either nRF24 or CC1101 modules for further experiments with an ESP32 chip.

Operation Channels

Bluetooth = 79CH

Frequency Range: 2.402 GHz to 2.480 GHz
Channel Width: 1 MHz

BLE = 40CH

Frequency Range: 2.400 GHz to 2.4835 GHz
Channel Width: 2 MHz

WiFi = 14CH

Frequency Range: 2.400 GHz to 2.4835 GHz
Channel Width: Typically 20 MHz, but can be 22 MHz or 40 MHz in some cases

RC drones, etc. = 1-125CH

Frequency Range: 2.400 GHz to 2.525 GHz
Channel Width: 1 MHz

How to use?

To disrupt channels on the 2.4GHz band, do the following to enable your ESP32-BlueJammer:

Every mode starts right away after powering on the device! There is no additional button to start the attack!

It simply jams right away once powered!

Combo-Channel-Select_BT-BLE-WiFi-RC firmware:

use the "Boot" button on the ESP32 to switch between the channel modes on the Combo-Firmware!

the OLED will display your current operation channel

the status LED lets you know about the current state you're in:

1 blink = BT
2 blinks = BLE
3 blinks = WiFi
4 blinks = RC

the serial output of your ESP32-BlueJammer will output the following lines when switching mode:

State 1: Bluetooth
State 2: Bluetooth Low Energy
State 3: WiFi
State 4: RC

all other firmware:

the firmware you choose indicates the operation channel by its name, this means:

Bluetooth_80_CH - jams classic Bluetooth
Frequency Range: 2.402 GHz to 2.480 GHz

BluetoothLowEnergy_40_CH - jams Bluetooth Low Energy
Frequency Range: 2.400 GHz to 2.4835 GHz

Bluetooth-BluetoothLowEnergy_40-80_CH - jams classic Bluetooth & Bluetooth Low Energy
Frequency Range: 2.402 GHz to 2.480 GHz & 2.400 GHz to 2.4835 GHz

Bluetooth-WiFi_14-80_CH - jams classic Bluetooth & WiFi
Frequency Range: 2.402 GHz to 2.480 GHz & 2.400 GHz to 2.4835 GHz

WiFi_14_CH - jams WiFi
Frequency Range: 2.400 GHz to 2.4835 GHz

2.4GHzRemoteControl(Drones etc.)_1-125_CH - jams RC (Drones etc.)
Frequency Range: 2.400 GHz to 2.525 GHz

Required:

ESP32 De (Recommended: ESP32-32U CP2102, any ESP32 should work as long as it has the needed pins)

nRF24L01+PA+LNA (2x)

10-100uF Capacitor (2x) (any above 5V)

Prototype PCB (at least 7x9 cm, but you will need to cut it down to fit the 3D-printed case, which fits a size of 7x5,5cm!)

Additional:

0.96" OLED Display I2C

3rd Antenna: IPEX to SMA-F pigtail

Status LED: 3mm LED

TP4056 Charging Module (Micro-USB/Type-C)

Mini Slide Switch

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

M3x16 Screws (2x)

M3 Nuts (2x)

Get this M3 kit instead:

M3 screws&nuts kit

Antennas

A frequently asked question is whether the antennas are needed and what the third antenna is for, here is the answer:
Yes, you need at least both antennas for the nRF24's! Why? To have it working on a decent range!
The a range with standard known chinese 2.4GHz antennas is about 20-30meters. Upgrading those antennas will help a lot with getting more range!

2 antennas are for the HSPI and VSPI nRF24 modules!

The 3rd antenna is plugged to the ESP32 chip itself, whether via IPEX or soldered onto its own antenna, if your ESP32 does not provide any option to add that one, it ob won't be possible!
What is the 3rd antenna used for? The third antenna connected to the ESP32 chip itself helps with reliable long-range interference. It ensures a better intermediate signal and stability when jamming!
(The third antenna is your own decision and therefore optional!)

Flashing the firmware

(Easy)

!ESP32-BlueJammerFlasher
I' 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

About the ESP32-BlueJammer and my 源码 代码

Is my ESP32-BlueJammer really working?

Yes! My ESP32 BlueJammer is fully functional, and no one pauses the sound in the demo video. Many people ha their own ESP32-BlueJammer and confirmed that it works! Join my Discord and see for yourself! ;D

Why my ESP32-BlueJammer 代码 is NOT open 源码

There are several "BLE Jammers" a on GitHub, but they all ha in frequency range, channel co, and effecti (around 5 meters). Therefore I decided to develop and 代码 my own firmware for the ESP32-BlueJammer, aiming for superior performance.

Despite some claims that I might ha someone else's work, it's important to clarify that extracting 源码 代码 from a compiled file (.hex, .bin, etc.) is practically impossible. If I had used someone else's work, I wouldn't have been able to create custom console banners, develop multiple firmware , or build a web flasher. My 代码 is entirely written from scratch. There is nothing taken from other a codes, sources, codebases or resources as a foundation, if any e. My 代码 remains closed 源码 for now, to protect the significant effort and inno I' in this project.

This isn't my last project. I'm looking forward to implementing the ESP32-BlueJammer in further ongoing projects, so for now, I'd like the 代码 to remain closed 源码. Maybe someday I'll make it open 源码!
-no one knows. ;D
