• Sensors can only upgrade or downgrade when in charging status.
• Do not exit the update page or close the App during OTA.
• Network connection is required for OTA.
3.5.1 Firmware update
Once the sensor is connected, you can receive firmware update notifications if a new
version of firmware is available in Xsens DOT App. If no notification is received, the current
firmware version is up to date.
Follow these steps to perform a firmware update:
1. Put sensors in charging status
2. Open Xsens DOT App and connect the sensors you want to upgrade
3. Follow the notification badge, go to Advanced Device Firmware Update,
choose Upgrade
4. Check available new firmware version, select sensors to upgrade
5. Check release notes and start upgrade
6. Check upgrade status after all upgrade is done. The sensor will automatically reboot
after firmware upgrade
7. Wait 10 seconds for sensor rebooting and then you can connect the sensors again
to experience the new firmware.
3.5.2 Firmware downgrade
Firmware downgrade function is provided to downgrade the beta firmware versions to the
last stable version. Stable firmware versions cannot downgrade to any previous versions.
Moreover, if a new stable version is available, beta versions cannot rollback to previous
stable versions. You can only update the beta versions to the new stable version under this
circumstance. If downgrading to a previous firmware version is needed, contact technical
support.
