Error enabling Quaternion during logging using MetamotionC

Using MetaMotionC, Firmware 1.3.7
Connected to MetaBase Version 4.0.1 on Ipad (iOS 11.3.1)

After the most recent update to the Metabase, when I initialise the MetaMotionC in logging mode to record Quaternion data, it instead records linear acceleration data. When MetaMotionC is enabled in streaming mode, it correctly records Quaternion data. This bug occurs regardless of what other sensors are enabled at the time. I checked the output file (named ...LinearAcceleration.csv) and it is valid linear acceleration data. It seems to be an error with the sensor initialisation specific to logging.

Bug is repeatable using MetaMotion C running Firmware 1.3.6


  • Thanks for the report. We have found and fixed the issue, the next release should be on the App Store within 2-3 business days.

  • Cheers!
