What might indicate that a Bluetooth accessory is out of range?

When assessing the indicators of a Bluetooth accessory being out of range, the best choice is the scenario where the accessory is not viewable in the Bluetooth settings. Typically, when a Bluetooth device is within a functional range, it should appear in the list of available devices on your device's Bluetooth settings. If it is not visible at all, this suggests that it is either powered off, not in pairing mode, or indeed out of range.

The other scenarios provide different insights. For example, if the accessory is visible but cannot connect, it might suggest connection issues unrelated to distance, such as interference or compatibility problems. Emitting a continuous beep might indicate a different function or alert state rather than simply being out of range. A solid blue light typically signals that the device is powered on and functioning properly, rather than indicating it is out of range.

Thus, the absence of the accessory from the Bluetooth settings is the clearest sign that it is not within the operational distance required to establish a connection.
