I made up a very simple app proposal (basically recording the telemetry info and trying to follow an object by analysing the FPV image. I don't think they looked at it though - I got back an email in chinese with a link that let me download the sdk's (there's one for IOS and one for Android). Though I've been writing java apps for nearly 20 years (since 1995) I've never written an Android app so I only asked for Level 1 access. Probably won't get very far with the SDK as (a) I'm very busy with building a new rig for kite aerial photography and a tiltable mount for an S100 to use with my PV and (b) I'm 73!
The SDK's are quite big some 40MB of stuff in each with a sample app as well as html docs etc.
