Syncing two iOS devices over bluetooth

I'm not sure if this one is even possible, but I thought that I should ask. I need an event to be triggered on two (or more) ios devices at the exact same time. Right now I use Bluetooth to trigger the event on all devices, however, as expected, there is a small (or not so small, depending on many factors) delay.

Is开发者_如何学JAVA there a way to achieve this? Or should I forget it?

Depending on how demanding your requirements are, you could use something like the NTP protocol to synchronise the device clocks, and then send a specific time at which each device should trigger the event.
