Optical File Transfer Pro

क्यूआर छवियों का एक धारा के रूप में अपने फोन कैमरे के लिए छोटे फ़ाइलों भेजें।

This is the Pro version of the Optical File Transfer app - with the extended functionality.

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

Features :

• Requires no WiFi, no Bluetooth/NFC, no irDA and no USB cable to transfer files

• Both wireless and offline at the same time

• Minimal setup - when in download mode, just point the camera on the stream and wait

• Generates little radio frequency noise - so can be safely used in the airplane mode on the plane (might be also useful in the military)

• Can process requests to send file from other apps in the system (like your favorite file manager app)

• Can be used to broadcast file full-screen on TV in the loop - e.x. to allow people walking by to quickly grab some small pdf guide on their phones.

Additions over the free version :

• It does not have any adds - so little less laggy than the free version

• It can support transfer of files bigger than 5MB

• It allows you to choose download location of the received files

• Uses less space on the phone flash memory - because it does not use any ad functionality - so it also does not require any network permissions at all

Notes :

• To receive file from desktop PC - see a web version (Chrome and Firefox - IE11 not supported) : http://wrobel.wroclaw.pl/opticalfiletransfer/webuploaderjs.php

Also, windows native uploader at http://wrobel.wroclaw.pl/opticalfiletransfer/en/win/index.php or Linux uploader at http://wrobel.wroclaw.pl/opticalfiletransfer/en/lin/index.php - they are compatible with this app.

• Sending larger files is very time consuming - so this app does not intend to replace USB/WiFi way of file transmission at all.

It rather allows to quickly grab some small pdf/text/image from the PC/phone to phone, when you do not feel like searching for

USB cable/setup Bluetooth/WiFi just for that one small file.

• It also does not guarantee that transmission will ever succeed on every phone on the default settings. How fast phone can handle capture of the stream depends on the camera/general phone performance/stream brightness/camera ability to focus.

• Default settings are likely not optimal for every phone.

• If you have problems succeeding to transfer anything on default settings, experiment with the settings - slow down with FPS/allow more errors/etc.

• If you want to speed up a little bit, you can also tweak settings a little - towards faster ones - and find what is the limit for your phone/camera.

• Transmission settings affects only QR stream producer in upload mode - receiver in download mode only fits to what it sees.
