46  Using Arduino / Project Guidance / Re: [Big problem] Communication between multiple Arduino (with Xbee) without errors on: October 27, 2011, 01:12:29 pm
hi everyone!

I´m have the same problem. I have one coordinator and multiples end devices. The end devices sends continuosly data, for example temperature. But, suddenly the coordinator can send a request asking for something in particular. Here, i find the problem, `cause if the coordinator talk to a device, it need to differenciate the responser of the previous request from the constinously messages from the others end devices, what I mean is
I want to diference who belongs each message.

A solution could be: the coordinator reads a packet and determines from which end device is from. I could add the address of the end device but it means overload, and I was wondering if there is a easiest solution to solve the address of the source.

Another could be, send silence messages to end devices less the one you are insterest to talk and then just talk with him. Later iniciate again the continiously messages. But now, how could I stop a end device to send data.

well, sorry, my english is no good enough

I hope you could help me

thank you!!

I´ve one coordinator and several end devices. I want to difference the messages. A solution could be include the end device´s address in the data segment  but i was wordering if they are a simpliest way to do it.

thanks, and sorry, my english it´s not so good
