## What it is
FazJammer is an ESP8266-based firmware project that turns a NodeMCU plus an NRF24L01+ radio module into a device that jams Wi-Fi, BLE, and the 2.4 GHz band. It provides mode switching via a push button and status feedback on an SSD1306 OLED display, built with the Arduino IDE and RF24 library.

## Use cases
- jam wifi networks with esp8266
- build a 2.4 ghz signal jammer with nrf24l01
- interfere with bluetooth ble devices
- diy rf jammer firmware for nodemcu
- test wireless resilience against 2.4 ghz interference
- block wifi and bluetooth on a handheld device with oled menu

## When to choose
- you have the exact hardware (ESP8266, NRF24L01+, SSD1306 OLED, button) and want ready-made jamming firmware
- you want a simple button-driven device with multiple jamming modes (Wi-Fi only, BLE + all 2.4 GHz, idle)
- you want an MIT-licensed Arduino sketch you can modify for RF interference experiments

## When to avoid
- you need a legal or authorized wireless testing tool - radio jamming is illegal in most jurisdictions
- you want software-only Wi-Fi deauthing from a laptop or phone rather than dedicated RF hardware
- you need support for ESP32, 5 GHz bands, or hardware other than the specified ESP8266/NRF24L01 setup
