What is the reason why Glory Bracelet 4 stopped measuring heart rate during exercise from Huawei Health App?

Starting from Huawei Health App and stopping heart rate measurement during exercise may be caused by the following reasons:

If you start exercising from Huawei Health App and stop exercising through App, the bracelet will also stop heart rate measurement synchronously.

If you start exercising from Huawei Health App, during the exercise, if the Bluetooth connection is disconnected for more than 5 minutes and not reconnected, the bracelet will directly exit the heart rate measurement interface.

If you start exercising from Huawei Health App, take off the bracelet 10 minutes during the exercise, and the bracelet will automatically exit the heart rate measurement interface.
