Garmin has issued a firmware update for its CIRQA fitness tracker that has caused unexpected issues with heart rate broadcasting. The update, version 2.50, was intended to improve device performance but has led to Bluetooth connection problems. Users report that their devices now fail to maintain stable connections, disrupting real-time biometric data syncing with third-party apps. This has affected the usability of the CIRQA for those relying on continuous heart rate monitoring during workouts. Garmin has not yet released a fix, leaving users frustrated. The issue highlights the risks of software updates in wearable technology, where a minor glitch can significantly impact user experience.
