Version 3.2.1 — May 2013
- Encode firmware version in USB descriptor for improved troubleshooting.
- Corrected a bug that could cause the flash log to be corrupted during a reset recovery. No data loss occurred in instances of this bug, and a workaround was placed in ActiLife to fully recover data.
Version 3.1.0 — March 2013
- Fixed a bug that could cause USB communication failures.
- Changed battery warning threshold to extend the amount of time a user has to charge a device after seeing the LED indication (~36 hrs. @ 30 Hz or ~14 hrs. @ 80 Hz).
- Only firmware with the same or higher major version number (i.e. 3.x.x) may be programmed on a device.
- Implement 60 second epoch data collection on the device. This feature allows for up to 90 days of recording if raw data collection is disabled. Epoch records contain the following data: * X, Y and Z axis counts * Gravity projected counts using all three axes * Lux * Steps * Heart Rate (wGT3X+ and wActiSleep+ only) * Down vector (i.e. normalized gravity vector for inclination information)
Version 2.5.0 — June 2012
*Added ability to disable Idle Sleep Mode. This allows a device to never enter Sleep Mode when no activity is sensed. * Fixed an issue where a device might enter sleep mode in very low activity levels.
Version 2.4.0 — February 2012
• Added firmware to support new battery charger
Version 2.3.0 — December 2011
• Fixed a bug with 512MB devices that allowed units to continue taking data even though memory is full. • Fixed a bug where the root directory table gets corrupted and does not allow the unit to be downloaded. Data in this situation is actually good and can be recovered. • Fixed a bug that did not allow the red LED to continue to flash if a hardware error occurs to indicate the units needs to be sent back to ActiGraph (This is a single 0.5 second on, 0.5 second off, red LED flash).
Version 2.2.0 — September 2011
Increased accelerometer start-up delay to correct manufacturing test issues and also improve sleep mode reliability. False positives for detected motion that cause sleep mode to exit have been reduced.
Version 2.1.0 — July 2011
• Fixed incorrect logic that could cause up to 15 seconds of data at the very end of recording to be dropped. • Increased the battery log size to allow for longer diagnostic recording with 512 MB devices.
Version 2.0.0 — May 2011
• Implemented a more error tolerant firmware update process. • Lux and battery are now committed to non-volatile memory in a single batch to improve power efficiency. • Corrected USB and LED behavior when halting after a power interruption is detected in delay or active logging modes. • Fixed a bug that could cause loss of some battery log data.
