Hi, I did try it and it was working quite good when the devices (phone and laptop) were within ~30 cm. After increasing the distance and putting on the TV in the background it wasn't working that well any longer. I tried only the default protocol with audible frequencies (the ultrasound option didn't work, but my phone does not support the ultrasound option with my application too. guess it's hardware limitation).
I am willing to sacrifice bandwidth to achieve better reliability of the communication and I believe I was able to achieve it. Although, I haven't done tests with many other devices/conditions than my own, so my result might be biased.
