Ultrasonic alternatives in kodular

Dear community, I was looking for some solution in generating an Ultrasonic data transmission with kodular. It consist on a mobile sending and receiving ultrasound data for communication.
Is there any extension or possibility to generate those tones and translate them into data?

Thanks in advance.


Can you show an app on Google Play in which this is possible?

I was searching for this type of application in play store (for fun)
But I didn’t find this type of application

Google Pay (Tez) used this technology in past

I think you may not publish app on play store because this technology is owned by Google

Try using Sound Sensor component and emitting already recorded sounds (Ultrasonic)

Dear folks, actually there was an app that send ultrasonic messages called chirp but they were sold to Sonos and after that they removed the application from play and appstore.
