Get single latest telemetry item about mavsdk-python HOT 5 CLOSED

I don't think you can use position() as a polling interface unless you do something like:

async for position in drone.telemetry.position():
    return position

It is probably fine if you call that only once, but not ideal if you call it in a loop. The point is that we provide telemetry as a stream, and you have to consume it.

But you could totally update your state from that stream and write your own polling interface allowing you to get the latest value whenever you want, right?

Hi @JonasVautherin
you reccomended writing a polling interface to retreive the latest value, would you be able to give me an idea of what that would look like? We are trying to write a program that will need to call a function that returns the most recent position value and we can't quite get our heads around how to do this from the telemetry stream.
Thank you in advance.

Something like:

async for position in drone.telemetry.position():
    state.position = position

in a coroutine, and then when you want to access it, you do something like:

print(state.position)

Does that make sense?

That's brilliant thanks!
