Android Question dji getUltrasonicHeight with Java Object

[shb777]

This is my 101st question. I want to get the UltrasonicHeight, using the getUltrasonicHeight method.
It's in the class DJIFlightControllerDataType.DJIFlightControllerCurrentState I guess. But I don't
know how to do this with a Java Object. The DJI SDK documentation is very confusing to me. I'm
no java programmer. If you can do this, please explain to me the step by step process you use, so I can do these by myself, without always asking for help.

Try this:

Dim jo As JavaObject = st 'st is a DJIFlightControllerCurrentState
Log(jo.RunMethod("getUltrasonicHeightInMeters", Null))

Try this:

Dim jo As JavaObject = st 'st is a DJIFlightControllerCurrentState
Log(jo.RunMethod("getUltrasonicHeightInMeters", Null))

ok I'll try it.

It works! it only works at 30 feet and below, but that's where you really need it, when you're close to people. I don't trust the gps altitude. it's not
that accurate, and it only gives you the altitude relative to where you took off.

why does the dji documentation say that the class containing getUltrasonicHeight is
DJIFlightControllerDataType.DJIFlightControllerCurrentState

rather than

DJIFlightControllerCurrentState?

You should ask this question to DJI, not US.

You should ask this question to DJI, not US.

does that mean, that it doesn't make sense to you, because it doesn't make sense to me.

I realize it's not your job, to teach me how to read other people's documentation.

No.
But it make sense to ask this question in the DJI forum instead of the B4X forums if you think it is wrong.
