Thanks. As far as I can see, in terms of controlling the drone's movements, the current SDK seems to have everything I need. If all I'm trying to do is write a simple SDK wrapper to be able to fly the drone with a controller from my PC, am I correct in my understanding that it can be achieved with the SDK, usinge the "rc a b c d" set command?Initial SDK was much more limited than current (see SDK 1.0); but even today there are more known unofficial commands than the SDK offers (wifi configuration, video stream parameters, photo, ...). Just compare.
