Hi all,
When first using TelloFpv I noticed that after changing maximum altitude setting, with
Tello hovering up in the air, the app lost control of
Tello: no command nor menu was working any more. I had to exit the app, leaving
Tello hoverkng alone, and restart it to regain control. A bit scaring..
This happened to me on two different devices (mobile).
Additionally ( I think it was just after restarting, sorry don't remember exactely) the screen was not shown any video streming: it stayed black until I switched to camera and back to video mode.
I believe both behaviour are unintended, right?
In any case, greate app! Keep developing it.
One of the thing I like most compared to the official app is the better usability of the sport mode, which is often required when flying outdoor in some wind, thanks to expo.
One suggestion: also implement a "rate limiter" (mostly for pitch & roll) so that control value does not jump immediately to the joystick value but rather grows in time with a maximum rate (e.g. of the order of 1-2s to go from 0% to 100%). This should help avoid the sudden change in attitude when recording videos.
In fact, the feature (user configurable) could be automagically activated only when recording is on.
I believe that something similar is used by
Tello's firmware when in video mode.
