Version 4.4.0 — June 2011
- Enabled a global watchdog timer that will reset a device if it is not hit at least once per second. This is intended to prevent any possible firmware lock-ups from halting data collection prematurely.
Version 4.3.2 — March 2011
A firmware bug was corrected that caused bad inclination algorithm parameters to be configured during manufacturing. This manifests as a device always indicating a standing (1) value.
