Kali Linux includes several pre-installed utilities for Bluetooth reconnaissance and testing:

This will list the available Bluetooth adapters. Take note of the device name (e.g., hci0 ).

Capable of transmitting actual RF interference across the 2.4 GHz spectrum to block all signals.

While not Kali-native, many researchers use ESP32-based "BlueJammers" (firmware-level) and interface them with Kali for control. 🔒 Mitigation & Defense

You can create a simple script to flood a Bluetooth device with requests, essentially making its service unavailable. However, note that the effectiveness can vary widely based on the device, its implementation, and your proximity to it.
