ESP32 Quad N RF24L01 Plus Jammer Multi Band 2 4ghz RF Controller

Abstract

1. Introduction

This project allows an ESP32 board to control four nRF24L01+ modules for RF jamming (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer, ...) or channel sweeping across multiple 2.4GHz bands. Each module can be independently controlled and jam on its own channel. Modes are selectable via serial commands.

This guide shows how to connect four nRF24L01+ modules to an ESP32, using both HSPI and VSPI SPI buses.

2. Objective

ESP32-Quad-nRF24L01-Plus-Jammer is an open-source project for controlling four nRF24L01+ modules from an ESP32. It enables multi-band 2.4GHz RF jamming and channel sweeping for Bluetooth, WiFi, BLE, RC, USB, and video frequencies, ideal for RF research, testing, and security analysis.

This project demonstrates how C++, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C++ compiler (g++)
• Target board (e.g. Arduino, ESP32) where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/Electro-Gamma/ESP32-Quad-nRF24L01-Plus-Jammer-Multi-Band-2-4GHz-RF-Controller.git
cd ESP32-Quad-nRF24L01-Plus-Jammer-Multi-Band-2-4GHz-RF-Controller

1. Wire up the ESP32 and 4x nRF24L01+ modules as shown above.
2. Flash the provided firmware to your ESP32.
3. Open a serial terminal at 115200 baud.
4. Use the commands above to control the jammers.

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
