The Seismofit® System is comprised of multiple parts of software. Software release notes are grouped into four. Each section, contains information about the latest release:
  • App
  • VO2-max Estimation Algorithm
  • Web API
  • Device Sensor Firmware

App

V. 1.0.2

  • Fixes a bug, that could lead to the analysis being stuck at state “analyzing”. 

V. 1.0.1

  • Improved German Translation in the app
  • Fixes a bug where authentication token was invalid, but the flow in the app persisted. This should now be fixed. 

Known bugs or issues

  • After performing an analysis and returning to the overview of Seismofit devices, the user might need to select the Seismofit twice, before performing the next recording

V. 1.0.0

This release initiales the use of the VentriJect Clinical app on both iOS and Android operating systems.

  • App has been completely rewritten to Xamarin
  • Basic functionality as in V. 0.3.0
  • Sampling for Z-axis only for faster transferspeed between Seismofit®, phone and cloud. 

 

Known bugs or issues

  • On the result-screen, the normal VO2-max is not displayed
  • On Android, Seismofit® devices does not show up automatically in the device view, the user need to “pull down the list” to refresh and find the Seismofit® devices

V. 0.3.0

  • Updated workflow around JWT token
    • API v2.0.0 uses JWT token for authentication
  • Updated the base URL for the new API
  • Pop back to the correct controller, if a device disconnects
  • Testing with the new production API
  • Show serial number instead of device identification.
  • Switch to using Log instead of printing for internal testing

V. 0.2.0

First release of the software used for testing.

  • Bluetooth Low Energy Interface to Seismofit® Sensor
    • Start and stop of recording
    • Obtaining information about the device
    • Calculate CRC Checksum for transferred data
  • Contact information to VentriJect added
  • App searches for previous recordings
  • Show part of the recording ID and recording time, used as part of the testing

V. 0.1.0

  • Initial Bluetooth Low Energy Interface programmed

VO2-max Estimation Algorithm

V. 4.6.1

  • This updates brings improvements to the VO2-max estimation prediction for subjects with a high VO2-max

V. 4.5.1
