Xsens DOT New Features - Release 2020.2

Overview

  • Synchronization
  • Recording
  • Additional recording modes
  • iOS support full feature set
  • Heading reset optimization
  • Customizable power save mode
  • Xsens DOT Server

Synchronization

The synchronization feature will allow the timestamp of all sensors to be synchronised to a common time base. This is achieved by setting one of the sensors as a root node and all the others as scanners. The scanners’ timestamp is then adjusted with respect to the root. This will require a synchronization time before the start of measurement for about 10s.

This procedure will result in the SampleTimeFine to be similar across all sensors for each data point (minus some error). In terms of accuracy, Xsens synchronization algorithm will guarantee 1ppm (part per million) error after 30 minutes (equals to 1.8ms) and approximately 3ppm after 60 minutes (10ms). This is ideal for all cases where multiple sensors need to be connected at the same time.

Recording

The Recording feature allows for internal data storage and is available on Xsens DOT App and SDK. The maximum recording time is about 88 minutes and data export is available though Xsens DOT App via Bluetooth (export time will be about the twice of the recording time) or USB cable (export time approximately 1/8 of the recording). Additionally, it is possible to set a timer in order to stop the recording after a set duration. For further information on how to use Recording on Xsens DOT App, check out this guide.

iOS Full Feature Support

The iOS version of Xsens DOT App supports all features present in the Android counterpart. This includes:

  • All measurements modes
  • Heading reset
  • Firmware crash logs

For further information on feature compatibility across all Xsens DOT software packages and firmware, check the tables at the bottom of the article.

Heading Reset optimization

Heading reset function is optimized for simpler use on Xsens DOT App

Customizable Power Save Time

Power save mode timeout can be adjusted through Xsens DOT App for both advertisement and measurement mode. For further information on this feature check out the respective app guides.

Xsens DOT Server

A simple web server that will enable the use of Xsens DOT on any platform. You can find the open-source code on GitHub: https://github.com/xsens/xsens_dot_server

Firmware Compatibility table

The new firmware released will be version 1.4.0 (Stable). You can find the compatibility table below between firmware and app version.
