title: Bluetooth HCI snoop log not generated
body: <p>I'm running Android 4.4.2 and I enabled the "Bluetooth HCI snoop log" as described here <a href="https://stackoverflow.com/questions/23877761/sniffing-logging-your-own-android-bluetooth-traffic/23900782#23900782">Sniffing/logging your own Android Bluetooth traffic</a></p>
  
  <p>After turning bluetooth on and off I rebooted the phone. I could not find the log file in the expected location: </p>
  
  <pre><code>$ adb pull /sdcard/btsnoop_hci.log
  remote object '/sdcard/btsnoop_hci.log' does not exist
  </code></pre>
  
  <p>How can I get to the btsnoop_hci.log?</p>
