base on A minimal, simple and effective jammer that jams Wi-Fi, BLE and 2.4 GHz band. # ESP8266 BLE(Bluetooth) & Wi-Fi Jammer This project aims to develop a jammer using ESP8266 to interfere with BLE and Wi-Fi networks. The project utilizes the RF24 library to generate interference in the 2.4 GHz bands and provides user feedback via an OLED display. ## 📌 Requirements - **NodeMCU ESP8266** (or a compatible ESP8266-based board) - **NRF24L01+** module - **0.96" OLED SSD1306** display - **Push Button** (to switch modes) - **Connecting wires** ## 🛠 Required Libraries The following libraries must be installed in Arduino IDE: - [RF24](https://github.com/nRF24/RF24) - [SPI](https://github.com/espressif/arduino-esp32/tree/master/libraries%2FSPI) - [ezButton](https://github.com/ArduinoGetStarted/button) - [Adafruit GFX](https://github.com/adafruit/Adafruit-GFX-Library) - [Adafruit SSD1306](https://github.com/adafruit/Adafruit_SSD1306) ## ⚡ Hardware Connections | ESP8266 Pin | NRF24L01+ Pin | Description | |------------|---------------|-------------| | D2 (GPIO4) | CSN | Chip Select | | D4 (GPIO2) | CE | Module enable | | D5 (GPIO14)| SCK | Serial clock signal | | D7 (GPIO13)| MOSI | Data output | | D6 (GPIO12)| MISO | Data input | | 3.3V | VCC | Power supply | | GND | GND | Ground | | ESP8266 Pin | OLED Pin | Description | |------------|---------|-------------| | D5 (GPIO14)| SDA | Serial data line | | D6 (GPIO12)| SCL | Serial clock line | | 3.3V | VCC | Power supply | | GND | GND | Ground | | ESP8266 Pin | Button Pin | Description | |------------|---------|-------------| | RX (GPIO3) | Button | User input button (Another PIN Button to GND) | ## 🚀 Setup & Execution 1. **Make the connections**: Complete the hardware setup as per the table above. 2. **Install libraries**: Use **Library Manager** in Arduino IDE to install the required libraries. 3. **Upload the code**: Open `jammer.ino` in Arduino IDE and upload it to your ESP8266 board. 4. **Power up the device**: Connect your ESP8266 to a power source. The OLED screen will display jammer information. ## 📡 Usage When powered on, the device starts in **"Waiting Idly :("** mode by default. Press the button to switch between the following modes: 1. **BLE(Bluetooth) & All 2.4 GHz** (Interferes with all Bluetooth, 2.4 GHz devices) 2. **Just Wi-Fi** (Interferes only with Wi-Fi networks) 3. **Waiting Idly :(** (Puts the device in standby mode) The current mode will be displayed on the OLED screen. **Note:** You can connect external power like small lipo batteries. **Warning:** The nRF24l01 module getting extremely hot during use. This does not affect operation probably. But it may overheat your hand :D. ### Example photos   [](https://www.youtube.com/watch?v=4Mi9WWJwfMw) ## 📜 License & Legal Disclaimer This project is for **educational purposes only** and unauthorized usage is **illegal**.
