Pretty dope. I remember i wanted to do something like this but Todday didn't care for my idea of using a flash to trigger. I didnt think of using bluetooth speakers but that's an interesting solution to the problem. I guess you can ping the speaker and get back a time in ms which you can use to estimate the delay, pretty simple, if that's what they're using?

Oh yea, I didn't think about the delay. I'm guessing even at 100 meters there's gonna be a slight delay in sending that Bluetooth signal from phone to speaker
