title: Android BLE Connection time interval
body: <p>I am developing a BLE application on Nexus 4 using Android BLE API. I have a few questions/doubts:</p>
  
  <p>1) Is there a way to set/override the connection or notification interval of BLE central device. I have found that for Android, the default connection interval is fixed to 7.5ms. Is there a way to change this connection/notification delay interval settings.</p>

  <p>2)  On connecting to the remote device, I am facing an issue of getting disconnection after random period of time interval. There are many people facing the connection drop issue stating that android is unstable when they are using Android 4.3 API for BLE connection. Is there any solution for this?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>what else I observe here is when it is taking time to reconnect then it's coming with some L2CAP log ...following the log</p>

  <p>Any idea how can clear cahce mantain by L2CAP?</p>
