Elevator bug - wrest - 07-09-2019
Device: iPhone 6s, iOS 12.3.1
Phyphox: 1.1.0 build 7650 File format: 1.7
User interface localization -- russian.
In the Elevator experiment, height and velocity do not calculate and do not display (height and velocity windows are empty).
Acceleration records and displays O'k.
RAW data seems to be O'k: pressure and acceleration are recorded.
When exporting data to CSV, height and velocity are just set to zero:
Time (s) "Pressure (hPa)" "Height (m)" "Time (velocity) (s)" "Velocity (m/s)"

Restarting device (switch off and then boot on), deleting and re-installation the app does not help.
RE: Elevator bug - Sebastian Staacks - 07-09-2019
I have to admit that I am a bit ashamed that we did not find this in our tests before release and a bit surprised that it has not been reported before. Indeed, I can reproduce the problem on an iPhone 8 and we need to fix this fast (which unfortunately still means a few days plus Apple review time). I do not yet know exactly why this happens but it seems to be a problem with the new formula-node, because the older version of the experiment still works with the new version of the app.
So, until we have fixed it, you can simply open this version in phyphox:

Thanx, the link works O'k
RE: Elevator bug - Sebastian Staacks - 07-10-2019
The fixed version has been submitted to Apple this morning, so if the app passes Apple's review process smoothly, an update without this problem should be in the app store at some time tomorrow.
