I've seen this message several times in the past:
It appears that your barometer is 'stuck' -- i.e. it reports the same value for extended periods of time. You should check that your barometer is still working and is connected correctly. If you do not have a barometer, then please check your software and adjust it so that it does not report barometer values.
I've attached a screen capture (I know the text is small, but I needed to get the file size down. Sorry about that.). I know it's not right, and I ignore it. But I was curious if anybody else ever sees this message?
Kinda strange that the green thumbs up are there and the previous line before the error mentions "these values are in range so your barometer is probably calibrated correctly". ?.?. Haven't seen that one yet.
