title: Running thermometer-test Bluez 5.18 dbus error
body: <p>I need to develop an application with a bluetooth dongle that makes use of the thermometer profile. The thing is that, after succesfully pair and connect with the remote device, whenever I try to run the <code>test-therometer</code> file, I obtain the following error:</p>
  
  <pre><code>dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "RegisterWatcher" with signature "s" on interface "org.bluez.ThermometerManager1" doesn't exist
  </code></pre>
  
  <p>I have also tested the <code>test-heartrate</code>, and I obtain something similar:</p>
  
  <pre><code>dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "RegisterWatcher" with signature "s" on interface "org.bluez.HeartRateManager1" doesn't exist
  </code></pre>
  
  <p>I have successfully tested the dongle with bluetoothctl, so I can discard hardware compatibility issues. I'd like to know if I'm missing something while running the tests.</p>
  
  <p>I'm working under ArchLinux x86_64.</p>
