How To Block WIFI / Bluetooth / RFID / Cell Signals

Can you disrupt a Bluetooth signal?

The first and most crucial step is to operate a device that emits the same frequency as the device you're trying to jam. Signal jammers are the easiest way to do this, but it's also useful to know how to jam a Bluetooth signal with Android phones and other devices.

Why is my phone not discovering Bluetooth devices?

Even if Bluetooth is turned on, your phone itself might not be 'discoverable'. This means that a Bluetooth device you haven't yet paired cannot see your phone. To make it visible to other devices, open the main Bluetooth settings. On Android, phones remain discoverable so long as you stay on that screen.
