I am trying to send a short amount of data (10-15 characters) from one mobile device to another via (inaudible) sound within 1-2 seconds. I'd like to be able to deal with normal external noises (chatter, traffic, etc).
I have a software engineering background, but no experience working with sound or audio. Is there a known/documented solution to address this problem of reasonably reliable ultrasonic data transfer? If you know of a guide or some document that'll explain the concepts to me as I develop out a solution that would be really awesome.
I've researched a little bit on this topic, but have been unable to find something concrete for ultrasonic communication. Any direction would be much appreciated (and yes, I know I'm a noob here). Thanks.
