Please make sure that the latest version of Huawei Health App is installed on the mobile phone, and that the bracelet and mobile App are connected normally. Due to the influence of Bluetooth signal strength, data size and other factors, data synchronization may fail. It is recommended that you try to synchronize multiple times (at least 3 times).
If it doesn't work, please disconnect and reconnect to synchronize:
Android users: Please disconnect the bracelet from the App, re-pair the connection and try to synchronize again.
IOS users: Please disconnect the bracelet from the App, select "Ignore this device" on the Bluetooth page of the mobile phone system, re-pair the connection, and try to synchronize again.
If you still can't synchronize data through the above methods, please close and clear the App from the phone background, then reopen it and try to synchronize again.
