Firmware Releases


v2.5.0 (12/15/2017)

New Features

  • New Data Streams: EEG delta/theta/alpha/beta/gamma,EEG power sum, Acceleromter Std Dev.
  • REM Snooze! If the pushbutton is pressed or moderate to heavy movement is detected, REM stimulations will be immediately stopped (if started) and any further stimulations will be ignored for 5 minutes.

Breaking Changes

  • Sleep Staging algorithm now runs every 2 seconds.
  • Sleep Tracker stream now outputs an averaged sleep stage every 30 seconds (industry standard epoch length).

Bug Fixes

  • Fixed a bug that could cause the buzzer to hold a note indefinitely.

Bug Fixes

  • Fixes BLE Unknown firmware detection when connecting to certain Windows computers over USB.
  • Prevents crash loop when Aurora is booted up with a missing or failed SD card.

v2.4.0 (10/23/2017)

Bug Fixes

  • Prevent crash caused by enabling file output for the temperature stream.
  • Better detect file corruption when a file transfer is interrupted.

v2.3.0 (06/07/2017)

Improvements

  • Our earlier sleep staging algorithms were not perfect because the Aurora Wizards could only see into our team's brains. We’ve now embedded a Rune of Clarity into our Wizard’s staves. As a result, Aurora’s new sleep algorithm received a 20% accuracy boost.
  • Aurora is now better at distinguishing the awake stage from other sleep stages.
  • We caught certain Aurora elves slacking off at night, causing variations in data lengths collected. We’ve whipped them into shape and now Aurora’s sensor sample rates are more consistent for longer sessions.

Bug Fixes

  • BLE now reliably reports version info.

v2.2.7 (05/13/2017)

Bug Fixes

  • Fixes crash caused by playing a buzzer song while another one is in progress.
  • Fixes shutoff delay / rewind parameter mixup in LED transition effect command.

v2.2.6 (05/7/2017)

Improvements

  • Significant battery savings while using BLE. Aurora can now run for 15+ hours on a single charge.

Bug Fixes

  • Fixed bug that caused session transfers to occasionally fail due to a missed byte while performing streaming decompression.

Downloads


v2.2.4 (04/20/2017)

Improvements

  • Faster BLE transfers.
  • Longer advertising after BLE disconnection (5min).
  • Pushbutton now triggers advertising for 1 minute if not connected and no profile is running.
