The point to (multi)point will be sufficient, if you are using broadcast mode, and the sender can see each receiver.
Great, thanks, this is series 1 right? I may got with two anyway to give flexibility for future projects. Unless the way series 2 works hinders the synchronicity of course...
An XBee that is an end device or router can communicate with an XBee that is a coordinator, possibly through other routers.
So, the coordinator would need to send a message to all the end devices/routers. They would all have to reply "Ready" Then, the coordinator would have to broadcast a "Go" message. That rather defeats the purpose, eh?
...ah, so then that message could have the same delay to certain recipient Xbees... which would mean another ready message would need to be sent and the following "Go" message could still be delayed... sounds like a vicious circle!
I don't understand. How are you moving this audio data around?
It'll be through fading in one speaker while fading out the adjacent speaker to give the effect something is moving throughout the space, If a chain of speakers are treated in this way, the sound can move around a circle of speakers or along a wall for example. If this is done precisely with attention to detail some cool effects can be gained.
Keep the message as small as possible. Make sure that the coordinator can see all the end devices/routers, so that use of routers to retransmit the message is minimized (or, perhaps you shouldn't have any routers).
Great, thanks for your advice
