title: Connect to a Bluetooth LE device using bluez python dbus interface
body: <p>I would like to connect to a Bluetooth LE device and receive notifications from it in python. I would like to use the Bluez dbus API, but can't find an example I can understand. :-)</p>
  
  <p>With gatttool, I can use the following command:</p>
  
  <p>gatttool -b C4:8D:EE:C8:D2:D8 --char-write-req -a 0x001d -n 0100 –listen</p>
  
  <p>How can I do the same in python, using the dbus API of Bluez?</p>
