When first opening the app, you will see a screen that says "Please enable bluetooth." To get to the file selection portion, you must go to the settings for our app and allow bluetooth there.
The file selector should now be the first screen to appear. Select a file that you would transfer to another device then press the next button.
This now takes you to the device selection screen, where a list of nearby devices would appear. Select a device to start the transfer process.
The transfer screen now appears with the progress bar.
