Classic Bluetooth (2.0, 3.0) hopped across 79 channels at 1,600 hops per second. For a jammer to work, you had to predict the hop sequence or blast the entire band.
Ethical hackers and security researchers use these tools exclusively in or "Faraday cages" to test the resilience of new hardware. The goal of using Kali Linux in this context should always be to harden defenses —such as improving frequency hopping algorithms or implementing better authentication—rather than to cause disruption.
