# Bluetooth

> Choose Bluetooth menus in the order shown on the device.

Use the `Bluetooth` menu to inspect or test Bluetooth Low Energy (`BLE`) devices.

<Warning>
  Use only your own devices or devices you are explicitly authorized to test. `SPAM` and `AirtagTrigger` can cause numerous notifications on nearby devices.
</Warning>
