Which of the following describes why Bluestrike is used in testing Bluetooth devices?

• A. It can cause devices to disconnect and prevent reconnection.
• B. It helps identify Bluetooth version.
• C. Disrupting the frequency hopping mechanism to cause disconnection and prevent reconnection.
• D. It enhances Bluetooth pairing efficiency.

Answer: (C)

Testing resilience of Bluetooth links under interference. Bluestrike works by disrupting the frequency-hopping mechanism that Bluetooth uses to spread signals across the 2.4 GHz spectrum. When this hopping is interfered with, the link cannot stay stable, causing disconnections and making reconnection difficult or impossible. This lets testers observe how well a device handles loss of connectivity, how its reconnection and backoff logic works, and how secure pairing is affected under degraded conditions. The goal is to stress the link layer to reveal robustness, not to identify Bluetooth version or improve pairing efficiency.
