Hey wireless explorers!
Welcome back, I couldn’t be more excited to introduce nRFBOX v2.7.2, the latest evolution of our open-source, ESP32-powered toolkit for scanning, jamming, spoofing, and mastering the 2.4GHz spectrum.
With a redesigned menu system, new features like Wi-Fi deauth attack, Android BLE spoofing, and firmware updates via SD card, this release is more powerful and user-friendly than ever.
Let’s break it all down — and show you how to build your own.
🔍 What Is nRFBOX?
nRFBOX is an open-source Tool for the 2.4GHz band. Whether you're testing BLE, Wi-Fi, Zigbee, or other protocols, it’s built to scan, analyze, jam, spoof, and prototype with ease.
Powered by the ESP32-WROOM-32U and three NRF24 GTmini modules, it supports a wide range of experiments — from signal sniffing to spoofing Apple BLE devices.
Version 2.7.2 is the result of months of community feedback and adds powerful new tools alongside a refined user interface.

.bin
file on an SD card - 🔹 Enhanced Scanning & Jamming — Better performance across all protocols
- 🔹 Improved Sour Apple Attack — More stable spoofing of Apple BLE ads
- 🔹 Bug Fixes & Stability — Smoother handling of multiple NRF modules and SD access
🛠 Core Features (v2.7.2)
Here’s what makes nRFBOX a go-to wireless companion:
🔎 Scanner:
Scans the 2.4GHz band to detect Wi-Fi, Bluetooth, and other wireless devices, showing signal strength and channel activity in real time.
📊 Analyzer:
Dives deep into the 2.4GHz band across 128 channels, detecting activity from various protocols and displaying live traffic.
🚫 Jammer:
Disrupts wireless communications by sending noise on 14 selectable Wi-Fi channels. Note: Not a Wi-Fi deauther, and effectiveness may vary.
🛡️ Protokill:
Targets specific 2.4GHz protocols like Zigbee and Wi-Fi for stress testing and protocol-specific jamming.
📡 BLE Jammer:
Floods BLE advertising channels with noise, disrupting device discovery and connections. Also supports classic Bluetooth channels.
🎭 BLE Spoofer:
Mimics BLE devices by sending fake advertising packets. Customize device types and modes, now with Android support!
🍎 Sour Apple:
Spoofs Apple BLE advertisements (e.g., AirDrop, Continuity) to trigger unintended behavior or potential data leaks.
🔍 BLE Scanner:
Detects nearby BLE devices, even hidden ones, and provides detailed info about each.
📶 Wi-Fi Scanner:
Lists nearby Wi-Fi networks with details like signal strength and channel usage.
🔌 Wi-Fi Deauther:
Sends deauthentication packets to disrupt Wi-Fi connections—perfect for testing network security.
⚙️ Settings Menu:
Adjust OLED brightness, toggle NeoPixel feedback, and manage firmware updates.
🔄 Firmware Update:
Updates the ESP32 firmware directly from an SD card, no extra tools needed!
🧱 Hardware Breakdown
Build it on a breadboard or go pro with a custom PCB. Here’s what powers the box:
- ESP32-WROOM-32U – Dual-core MCU with built-in Wi-Fi & Bluetooth
- 3× NRF24 GTmini (LNA) – Backbone of 2.4GHz jamming and scanning
- 0.96" OLED...
