Support for multiple configurations in data over sound communication is provided.

1- Way Communication: The Sender sends encoded data to the receiver that decodes it. There is no communication back to the sender about the data receiver status. Thus, the sender device does not receive feedback about data received by the receiver or not

2. Two-way communication:

  1. Sender device sends the data to the receiver device.

  2. Receiver device decodes the data.

  3. Receiver device then sends back an acknowledgement to the sender device that the data was successfully received.

  4. Absence of any acknowledgement received by the sender device, can trigger re-trial of transmission of data.
