firstly read temperature for avoiding wrong calculation #51

emre-h commented 3 years ago

I have used the library and it was giving wrong altitude values because of not calling the readTempC() before calling readFloatAltitudeMeters(). Then I have called it and it has been fixed.

Thanks for the PR!

Does this method come from the datasheet? Why do you readFloatPressure twice?

Hmm, it looks like t_fine gets set in readTempC and is used in readFloatPressure.

It has fixed the wrong calculation. You can try it with or without my two-line containing commit. (it will probably give the wrong meter calculation without this commit)
