payloadType property
A code that identifies the content of the payload (0 for unknown, which is the default). If this code is less than 32768, it is a 'registered' payload type and the corresponding code should be added to the MAV_TUNNEL_PAYLOAD_TYPE enum. Software creators can register blocks of types as needed. Codes greater than 32767 are considered local experiments and should not be checked in to any widely distributed codebase.
