I hope this is the right forum for this question. You are all so smart anyways I am sure somebody will have an answer for me, or be able to send me off in the right direction. Basically I am trying to communicate wirelessly with between a mechanical device with sensors and my PC. I really like the AVR Raven concept of a tranceiver and microproccesor board that communicates with a USB stick plugged into the computer. But is this the best way for my computer to receive the signal? I am not going to use the Raven, but I am going to try and build something similar, and I want to use LabVIEW for signal processing.
The question that got me typing here is how does the receiver connected to the PC recognize the signal transmitted by the remote device? How do they know each other?
