That depends on the app you use.
On the native Tello app you can get an overview at options/bluetooth-joystick/game controller diagramm (*).
On the TelloFPV app you can map almost all functions to almost all buttons at your controller. Look at the menu/controller/mapping (*).
(*) The menu topics can be a bit different, because I only have the german titles.
I don't use the Ryze app anymore for obvious reasons so no clue about that. All I know is it has a fixed mapping.
With TelloFpv you can (and have to!) map the buttons and sticks as you please:
And then tune the sensitivity using usual RC tuning parameters:
All onscreen buttons remain functional, the controller buttons are just added to this. There is a lot more to this app, if you have it / buy it please read the PDF manual available under "menu => help"
Super prgramm you made. For intuitive youngsters the manual might be OK but for me not quite clear.
Preferring my GameSir T1d for flying above my old Android it is not yet quite clear to me how to 'map' (assign) gamesir buttons to the fpv app and vice versa...
Do preprogrammed GameSir T1d buttons still work, like L2 + up = flip fwd ? R2 + Y = still Take-off?
Yaws, rolls and pitches not too important to me.
Circling POI, take-off / land, take photo/video, circle for video, wider circle for photo's, are of omportance to me.
I'm not quite sure if GameSir or fpv apps steer the Tello drone...what to do to get things strait?

First you have to go to the "controller" screen and scan for a new controller. The T1d will show up, it could take 2-3 tries sometimes. Then select the T1d controller in the "Student" drop down. That way onscreen controls are "master" and you can always overrule the T1D controller with the onscreen controls if something goes wrong.
Then go into "Mapping" and select the T1D controller. There you can check the mapped functions and assign new functions to the buttons. The Ryze app button mappings (L2+up = flip etc) does not work. TelloFpv does not support dual button combinations. You can use long press, short press instead.
Hope this helps!
the circles are only shown when pressing "..:". these are flip buttons for flipping the drone
You can define the buttons to your personal liking. There are more functions than buttons actually.
You can also set two functions on one button. One function for short press, another button for long press as mentioned in the manual.
And then just try it. Will all come naturally one piece after the other.
