ESP32-Powered Tool to Scan, Jam & Spoof BLE, Wi-Fi - nRFBox

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.

🛠 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!
