title: LEAdvertisingManager1 missing from DBus.ObjectManager.GetManagedObjects
body: <p>I'm running tests with my home computer running Ubuntu and Python 2.7 in the hopes of having Raspberry Pi 3 advertise using BLE with custom services and characteristics. I've installed Bluez Version 5.42 (using the recommended method) on both devices as well as dbus-python. My computer and Raspberry Pi both are able to advertise using the <code>hci0 lescan 0</code> command, but I'd like to advertise with the bluez example scripts, example-gatt-client.py and example-advertisement.py found <a href="https://github.com/RadiusNetworks/bluez/tree/master/test" rel="noreferrer">here</a>, as I want to use my own custom characteristics.</p>
  
  <p><strong>Home Computer - Kernel version 4.4.0-31 generic</strong></p>
  
  <p>I'm able to create custom characteristics and advertise by running example-gatt-server.py and example-advertise.py with no issues on my home computer. The one snag I had was I needed to enable Bluez experimental mode by adding <code>--experimental</code> to the bluetooth.service file located in <code>/lib/systemd/system/bluetooth.service</code>. Also installing the dbus-python library was a bit of a pain, as I had to build and install it myself for Python2.</p>
  
  <p>The advertise.py script looks for a specific advertising interface called "org.bluez.LEAdvertisingManager1". The gatt-server.py script looks for "org.bluez.GattManager1". I can check if that interface exists by running the following command: </p>
  
  <pre><code>dbus-send --system --dest=org.bluez --print-reply / org.freedesktop.DBus.ObjectManager.GetManagedObjects
  </code></pre>
  
  <p>These interfaces are found and work fine on my home computer. The scripts run without issue.</p>
  
  <p><strong>Raspberry Pi - Kernel version 4.4.38-v7+</strong></p>
  
  <p>With the same bluez version and the experimental features enabled, I run into this error when trying to run advertise.py:</p>
  
  <blockquote>
    <p>LEAdvertisingManager1 interface not found. </p>
  </blockquote>
  
  <p>And when I execute the command "systemctl status bluetooth" it shows the experimental flag is enabled, but I don't see LEAdvertistingManager1 when running. </p>
  
  <pre><code>dbus-send --system --dest=org.bluez --print-reply / org.freedesktop.DBus.ObjectManager.GetManagedObjects
  </code></pre>
  
  <p>I can however run the gatt-server.py script without issue which means "org.bluez.GattManager1" is found and working properly. What am I missing here?</p>
  
  <p>I've searched this issue, but the only suggestions were to enable experimental features and ensure my kernel is >= 4.1.</p>
