title: How to access Bluetooth low level functions in pybluez?
body: <p>Are there pybluez wrapper functions for lower level bt functionality? I couldn't find anything in the docs. What I need to use is equivalent functionality to:</p>
  
  <pre><code>l2ping (single ping)
  hcitool cc
  hcitool rssi
  hcitool lq
  hcitool tpl
  hcitool dc
  </code></pre>
  
  <p>Is there a way to access that from pybluez (or actually any other wrapper and/or scriptable language)?</p>
