Good day to all. Rested against the currently incomprehensible task.

It became sharply necessary to transfer bytes (bits) using sound. The bluetooth transmitter and bluetooth receiver is used. (Not microphone - speakers).

I looked in the FFT, but something could not figure out how to encode the bytes based on the frequency of the wave.

Please push the solution. Thank you in advance

  • 0x00 - 220Hz, 0xFF - 7040Hz, all that between - to distribute as desired. Frequencies can also be taken at will to others. Here, for simplicity, the illustrations are used for the small and fifth octaves. - Enikeyshchik
  • @ Enikeyschik, thanks. But do not tell the library which accepts wav 16 bit 44100 Sample Rate and 2 channels at the input and encodes (or decodes the data). Generation of a wav stream with the necessary frequency for decoding on the receiving side. There are such? - dailysse
