I would like to measure the distance between a bluetooth speaker and the phone's microphone by measuring the time it takes sound to travel from the speaker to the microphone. The acoustic ruler is already very close to this. It just needs to have a button that starts the timer and triggers the bluetooth speaker to play a sound, and then stop the timer when the microphone detects the sound.
Has anyone done anything like this before?
