receivedExtendedAltitude is only called when an altitude-TAG is found in the Navdata (that's not the case when in Demo mode). receivedAltitude is called even in Demo mode. Altitude is > 0 only if the drone is actually flying. When it is not flying (e.g. if you hold it in your hands), altitude is always 0.

A new plugin has been added to the Control Center to demonstrate altitude.
