How to use the app?
You will need an audio cable and two mobile phones running Android with a API higher than 15 (Ice Cream Sandwich MR1) to use the app. The audio cable the app is tested with is shown in the picture below.
In order to use the app, the ends of the cable have to be connected properly. Therefore, connect the end with the three black stripes to the receiving mobile phone and the end with the two black stripes to the transmitting mobile phone.
Now you can start sending files. If you would like to turn OFDM transmission off or turn (7,4) Hamming coding and interleaving on, open the settings of the app and adjust them accordingly.
