Wait for the upgrade prompt on the phone, click OK, and the phone will start searching for the bracelet.
After the search is completed, the bracelet will be upgraded, the mobile phone will prompt that data is being transmitted, and an "arrow" sign will appear on the bracelet. Only after the upgrade is completed will you be prompted that the upgrade is successful. Click "Finish" and the bracelet will also be turned on.
Then click the settings in the upper right corner of the bracelet application on the mobile phone, select my bracelet, and click O-Band to find the latest version of the bracelet.
