Playing with Tello for the last two weeks, such a nice little drone, the SDK really makes it interesting to play with. Hopefully i'll get a build of the Tellometrik ready during next week and share it here.
Yes, keyboard controls and "mission files" are something that i will try to look into, i'll see if i can reuse some of the implementation for mission files already available at jsolderitsch/tello-nodejs and keyboard control from here: SovGVD/nodetello
Ideally i would like for tellometrik to
support more advanced controls (height and speed limits, ev values, more detailed flight logs etc) that are not documented in the sdk.
store flight logs in csv files locally
record video and convert it to .mp4 files on demand
