A4100 Release Notes 3.1.0

We are pleased to announce the first public release of Mason OS for the Mason A4100 smartwatch!

Hope you enjoy and love this product as much as we do!

! The A4100 is not a medical device and should not be used for medical purposes. The A4100 is not intended to diagnose, treat, cure or prevent any medical condition. If you are experiencing symptoms of a medical condition or have concerns about your health, you should seek the advice of a medical professional immediately.

Mason Hardware Framework SDK

With the Mason OS 3.1.0 release, customer applications will be able to integrate with the Mason Hardware Framework SDK in order to interface with the built in A4100 ECG sensor technology. ECGSensorManager lets you access the device ECG sensor and the ECGEventListener callbacks can be used for ECG sensor events.

Please note that the existing Mason Framework SDK, designed to give your application privileged abilities on the Mason OS, is also available on the A4100. We are bringing forward all the goodness of the Mason framework to the A4100 smartwatch.

A4100 Sensor Technology

ECG

Mason has designed and integrated an ECG sensor stack and application-level support which is all available through the Hardware Framework SDK.

With the Mason OS 3.1.0 release, your application will be able to access sensor data to measure:

User presence
Heart Rate
Heart Rate Variability
Stress
Energy

And to perform tasks such as:

User (un)enrollment*
User authorization*
User metadata (age, height, weight)*

*The smartwatch is not associating any sensor data to an end-user. The application is responsible for that.

See Mason Sample applications for examples on using heart rate in your application

PPG

With the Mason OS 3.1.0 release, your application will be able to access sensor data to measure:

Respiration Rate
Heart Rate
Blood Oxygen (SP02)

Since Mason OS PPG support has been integrated with Android Hardware Sensor framework the Android standard APIs can be used. See the Android documentation for additional details.

Also see Mason Sample applications below for examples on using respiration rate in your application

SP02

With the Mason OS 3.1.0 release, your application will be able to access sensor data to measure:

Blood oxygen level

See Mason Sample applications for examples on using respiration rate in your application

There are a set of sample applications including source code that will help you get started on building your application using wellness metrics such as heart, breathe, blood oxygen etc.

Android Security patches

Stay up to date with the Android 8 security patches. Mason OS is integrated with the latest Android 8 security patches.

Mason OS Configurations

As before all Mason OS configurations can be found at https://docs.bymason.com/devices

Mason OS User Interface

The Mason OS experience has been updated to fit the navigation and visual experience that is needed for the screen size of a watch. You will notice a difference between the interface of the watch versus our handheld (6”) and 8” and 10” tablets

There is a new keyguard experience and also updates to:

Application launcher
Settings

QR Code Provisioning

We introduced the ability to provision a device through QR Code scanning. This is to accommodate the watch screen size since the manual setup UI on the watch is quite strenuous on the eyes.

Please see https://youtu.be/ZVEvTHPLAvg for details on how to provision your device using a QR Code.
