title: How can I retrieve the data from a bluetooth device?
body: <p>I have a bluetooth device, in particular a Heart Rate Measurement.</p>
  
  <p>The bluetooth standard for these kind of device is the 180D 2A37. </p>

  <p>I would like to get the measurements. How can I do?</p>
  
  <p>At the moment, I am able to connect and pair with my device using the Bluetooth API (<code>BluetoothSocket</code>)</p>
