A researcher blocked the iPhone with Flipper Zero via Bluetooth by activating an infinite number of fake pop-ups on the smartphone. The specialist used modified firmware for Flipper Zero. Through the device, he started a procedure of constantly sending a simulated AirPods pairing signal via Bluetooth.

If you close the notification window, another one immediately appears and so on. As a result, it becomes impossible to use an iPhone in the Bluetooth range of Flipper Zero. The attack works even when the AirPods mode is enabled. It can be interrupted only by completely disabling Bluetooth in iOS settings, not by tapping the icon in Control Center.
