title: iPhone to RS-232 via Bluetooth
body: <p>I'm looking to connect my iPhone to an RS-232 serial device via Bluetooth. Has anyone implemented this successfully and can offer advice on hardware to use? It's kind of tricky because of the need for the Apple Authentication Processor with the device. The best potential device I've found is <a href="http://www.connectblue.com/products/bluetooth-products/bluetooth-modules/bluetooth-iphone-ios-accessory-module-obs414/">this guy</a> but it only comes in an embedded package, its serial port interface is just logic-level UART rather than line-level RS-232, and I can't find a supplier with it in stock.<br>
  Any thoughts would be appreciated.  </p>
  
  <p>I'm considering just using WiFi to serial instead, but please ignore that possibility for the purposes of this question. </p>
