title: iOS WiFi probe interval
body: <p>I am writing an app which connects via WiFi to a proprietary device.  The proprietary device acts as a WiFi access point.</p>
  
  <p>When the device powers down, the WiFi connection is terminated, as I would expect. </p>
  
  <p>The iPhone continues to send probe requests, looking for networks to connect to.  It  follows an exponential backoff algorithm for sending probes.</p>
  
  <p>My problem is that eventually the intervals between the probe requests sent by the iPhone are longer than the timeout on my device, so they don't make a connection.</p>
  
  <p>I am using the Reachability code and it works as I would expect.</p>
  
  <p>It seems that pressing the home button will reset the backoff and send a probe request immediately. Does anyone know of a way to have my app do something similar?</p>
  
  <p>Thanks for any help.</p>
