Optical File Transfer Pro

This is the Pro version of the Optical File Transfer app. Send small files to your phone through camera - as a stream of QR images. Features : • Requires no WiFi, no Bluetooth 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 RF noise - so can be safely used in the airplane mode on the plane • Can process requests to send file from other apps in the system (like your favorite file manager app) Notes : • To receive file from desktop PC - see the supplementary Windows program at http://wrobel.wroclaw.pl/opticalfiletransfer/en/win/index.php or Linux program at http://wrobel.wroclaw.pl/opticalfiletransfer/en/lin/index.php - they are both 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. • Free version supports files up to 1MB in size. 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 1MB • 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
