Hello I have read the details. It seems you need to connect the DAC module with STM 32 board to demodulate the audio. I want to discuss more about the project. Thanks, Chanchal Kumari

i don't think we can receive or transmit ultrasonic data though microphone and normal speakers..you will need ultrasonic transducer and circuits to work this ...i may able to design the circuit for you(and PCB)

Hi, I can do this modulation and demodulation for you. I was working with ultrasonic (and sonic) in my bachelor thesis. I also know the stm32 (I can implement this on discovery board). I am very excited about this project! I am proficient in C and C++, also my skills are backed by work experience as an Embedded Software Engineer. I can share with you my CV. Can we have a chat?
