Fitbit Air Firmware Patch Targets Data Sync Glitches
Google is pushing a firmware update, version 20001.253.2, to the Fitbit Air. This release follows two major updates to the Google Health app and aims to resolve persistent friction regarding exercise data exports and connectivity stability.
Version Discrepancies and Deployment
This new build replaces the previous 20001.245.19 iteration. Users should note that Google uses different numbering conventions across mobile platforms: the Android version of the app displays the update as 67.20001.253.2, while the iOS version lists it as 20001.253.2. Despite the naming split, the core software remains identical.
Installation is managed through the Google Health app. When the update is ready, a “Device update” card will appear in the Today feed or on the device settings page. Unlike legacy wearables, the Fitbit Air does not require a charging state to update; it can remain on the user’s wrist during the process, which typically takes a few minutes.
Fixing TCX Exports and Connection Drops
The update arrives as a direct follow-up to Google’s post-launch feature roadmap. It addresses two primary technical hurdles:
- TCX Export Accuracy: A bug causing incomplete data in TCX file exports has been fixed. This specifically affected exercises tracked via the Fitbit Air using connected GPS, as well as data aggregated from multiple devices or apps linked to Google Health.
- Connectivity Resilience: The update improves how the Google Health app behaves during live tracking sessions when the connection between the wearable and the smartphone is interrupted.
Future Roadmap and Ecosystem Stability
Google is not stopping at these immediate bug fixes. The company confirmed it is continuing to work on expanding the range of exercises the Fitbit Air can automatically detect.
Installation Quick-Start Guide
Do I need to charge my Fitbit Air to install this update?
No. The device does not need to be on a charger to install firmware version 20001.253.2.
How do I know if the update is ready for my device?
Google indicates that a “Device update” card will appear in the Today feed or on the device page within the Google Health app once the firmware is available for your specific unit.
What is the main benefit of this update?
The update primarily addresses data integrity for TCX exports and improves app behavior during live exercise tracking if the connection to the device is lost.
