Garmin CIRQA firmware update breaks Bluetooth heart rate broadcasting
Garmin's CIRQA fitness tracker is experiencing Bluetooth heart rate broadcasting failures following the August 20 firmware 2.50 update, according to user reports on a Gadgets and Wearables forum thread. Affected users say Bluetooth connections cycle between connected and disconnected on Garmin Edge devices, while broadcasting fails outright on apps like Zwift, TrainerRoad, Rouvy and Strava, plus Bluetooth-enabled gym equipment. ANT+ connections remain unaffected, and a Garmin representative confirmed the issue has been escalated internally with no fix timeline given yet.
