Mbient app accelerometer data is different

Holding the MetaWearR device in any fixed position, I log the data from the mbient app. Then opening our app, with the device in exactly the same position, our log returns different values. Eg mbient app: X=0.158 Y=-0.01 Z=0.992 but in our app X=0.52 Y=0.152 Z= -0.817

Quite a difference! Thank you for any help.


  • What iOS API version are you using and what is your code for processing the accelerometer data?  The data from the app is what you would expect for a board laying flat on a table so I find it odd that your app reports completely different values, namely opposite Z values.
