If we have other Bluetooth devices, such as laptops, smartphones or smart TVs paired with the OnePlus smartphone, we can send any file.
It doesn't matter if it's a photo, video or PDF file.

After tapping the Share button, we can select Bluetooth as an app and choose the recipient or the paired Bluetooth device.

Note: In this guide we only select and send an image or photo. This is for illustration purposes only. More options are available.
