title: External Accessory reading problem
body: <p>I need to receive data periodically through a BlueTooth External Accessory.</p>
  
  <p>I implemented an event-driven model of EA's streams. However, the initial transmission from bluetooth is always delayed. For example, if each packet was 15 bytes long, the stream delegate would not fires until about 150 bytes.</p>
  
  <p>Will polling help?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>Also I found it hard to recover the session after the app switching back from background to foreground. Trying to open session again would fail. Any idea?</p>
