I would say it is not option at all with the Typhoon H. DJI has it built into their App Software. Yuneec would have to do the same thing but currently they Yuneec app on the ST16 is very basic. Possibly in the future they could add this feature.
the ST-16 will never be able to stream because it lacks Cellular board. plus the st-16 can not connect to a wifi router and be connected to the Cgo3 wifi at the same time
