We need to implement an ultrasonic data transmission between a Computer and a board (IC = STM32, or nordic, ......)
On computer must be only software to modulate the data in audio then on board only need to demodulate the audio in data. On the board we get the data from microphone.

Hello I have many years experience in the STM32, nrf52xx, and PCB design, so i can help you do this project quickly, pls inbox to me for more detail. Thanks & Regards
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)
