Ultrasound more powerful

[carlosguedes]

Hello Brian, is there any configuration on ultrasound profile that can be made to extend the range transmission for ultrasound communication? I tryed more gain, and other variables and I could not get better results. Can you give me some tips on how transmit better at 1 meter distance? Thanks

Would this be possible?

I'm interested in this too, I ran the example locally and tested it on 2 phones and it worked up to 30 centimeters with an ultrasonic profile. I would like to know if this range can be expanded, for example, up to 5 meters?
