Optical File Transfer Pro

Send small files to your phone through the camera as a stream of QR images.

Features:

• No WiFi, Bluetooth, NFC, IrDA, USB cable or internet connection required for transfer
• Wireless and offline at the same time
• Minimal setup: in download mode, just point the camera at the QR stream and wait
• Can send files shared from other apps, such as file managers
• Can broadcast a file full-screen in a loop, for example from a TV or monitor

Notes:

• To receive a file from a desktop PC, use the web uploader:
https://wrobel1989.bitbucket.io/

It runs fully in the browser and is compatible with this app.

• Larger files can take a long time to transfer. This app is not intended to replace USB, WiFi, Bluetooth, NFC or other standard transfer methods.

• Transfer reliability depends on camera quality, phone performance, screen brightness, focus and selected transfer settings.

• If transfer is unreliable on default settings, try lowering FPS or allowing more errors.

• Transfer settings affect only the QR stream producer in upload mode. Download mode adapts to the stream it sees.
