title: Wireless communication: AVR based embedded system and iPhone
body: <p>What is the best way to realize wireless communication between an embedded system (based on an AVR controller) and the iPhone? I think there are only two options: either WiFi or BlueTooth. The range is not really a problem, since both devices should stay in the same room.</p>
  
  <p>I have no idea, if there are any useful WiFi boards that can be connected to an AVR based microcontroller system (or any small microcontroller), any hints would be highly welcome.</p>
  
  <p>I guess the better solution would be BlueTooth, but there is also the problem: which BlueTooth board is best suited for attachment to an AVR system, and is it possible to use the iPhone BlueTooth stack for (serial) communication over BlueTooth with the AVR device.</p>
  
  <p>I hope that somebody already realized such a system and can give some helpful tips...</p>
