I have 2 arduinos(uno and mega) each of them fitted with an xbee shield. I got both them to send me back OK when i send +++ to them, sometimes I need to seed two or three times before i get an answer, any ideas why?
Well what i want to do is to take the value read on analog0 from one of the arduino send it to the other one, the other arduino also reads analog input at A0 and then send both values + timestamp to my laptop over usb. Sth like this Time, A0Local,A0Remote
The problem is that I have problem finding any good tutorials to do this.
I have these XBees: http://www.sparkfun.com/products/9097

this shield on the mega 5V: http://shieldlist.org/dfrobot/mega-expansion-1-1
any tip were to find information on how to do this would be appreciated.
