moveByChanged uninitialized

Hi!

I am trying to access the moveByChanged event message, but I get an error message saying that it is uninitialized.

My code:
import olympe

from olympe.messages.ardrone3.PilotingState import FlyingStateChanged, moveByChanged
from olympe.enums.ardrone3.PilotingState import MoveByChanged_Status

drone = olympe.Drone("10.202.0.1")
drone.connection()

drone(
    olympe.messages.ardrone3.Piloting.TakeOff()
    >> olympe.messages.ardrone3.PilotingState.FlyingStateChanged(state="hovering", _timeout=15)
    >>olympe.messages.ardrone3.Piloting.moveBy(1, 0, 0, 0)
    >> olympe.messages.ardrone3.PilotingState.FlyingStateChanged(state="hovering", _timeout=15)
).wait()


print("Moveby changed :" ,drone.get_state(moveByChanged))

The error message happening at the last line:
RuntimeError: ardrone3.PilotingState.moveByChanged state is uninitialized

Should we not be able to access the last received moveByChanged with the .drone.get_state(…)? Have I done anything else wrong?

From my current understanding, I would guess that I have received at least two moveByChanged event messages by the time of printing, one when sending moveBy and one when the moveBy finished. I this correct?

In my log, i can’t find any received event messages named moveByChanged. Is there a way to change the verbosity level of the logging?

Anafi sends the moveByEnd event after a moveBy command.

I think that the moveByChanged message is only sent by Bebop and Bebop 2.

For Anafi, you should get the moveByEnd event only after a successful moveBy.

For an Anafi, you shouldn’t have received any moveByChanged event message.

If you really want more logs, you can increase the log level to “debug” (4).

drone = olympe.Drone("10.202.0.1", loglevel=4)

You should then see in your logs every message received from the drone.

Hi ndessart, thank you for the quick reply,

Would it be possible to get similar information(dX, dY and dZ) after canceling a moveBy on anafi that the moveByEnd and moveByChanged provides?

This would need an Anafi firmware update.

You should add a message to the wishlist topic created by @Jerome and explain there what you’d like to see in a future release. Thanks

Thanks again for a quick answer.

If it is not yet implemented, I fear it is to late for me. I only have until the end of the summer. :frowning:

The wishlist seemes like a good idea. :slight_smile:
