What action must be taken if a Bluetooth connection is required for AirDrop between devices?

For AirDrop to function properly between devices, enabling Bluetooth on both devices is essential. AirDrop uses Bluetooth to discover nearby devices and establish a connection. Once the devices are detected via Bluetooth, they then use Wi-Fi to transfer the files, which allows for faster data transfer rates.

If Bluetooth is not enabled on either device, they won't be able to recognize each other, preventing the AirDrop feature from working altogether. Therefore, enabling Bluetooth on both devices is crucial for initiating and maintaining the file-sharing connection through AirDrop.
