⚠️ Attention: If the application displays the error “The device is already paired,” this means that the bracelet was previously connected to another phone. You need to reset the tracker settings through the menu of the bracelet itself or unlink it in the application on the old device.

To complete the procedure, press the “Confirm” button or the checkmark on the bracelet screen, if such an action is required. The synchronization process can take from 30 seconds to several minutes, depending on the connection speed and the need to download updates.

Firmware update and basic settings

Immediately after successful connection, the system will most likely offer to update the tracker software. It is strongly recommended to perform this action without putting aside, since new firmware versions often contain corrections for errors in the operation of the heart rate sensor and improved connection stability.

Make sure that the bracelet is near the phone and the battery level is at least 20%. The update process cannot be interrupted: if the connection is broken while recording data, the device can go into service mode, from which it is difficult to remove it without special equipment.

Solving common connection problems

Even if you follow all the instructions, users may encounter technical failures. The most common problem is that the phone stops seeing the bracelet after the connection is broken. In this case, the first thing you need to do is restart both devices: turn off and turn on the smartphone, and also restart the tracker through the settings menu.

If rebooting does not help, try removing the device from the list of paired ones in your phone's Bluetooth settings, and then removing it from the Mi Fit application. After this, complete the connection procedure again, starting with searching for the device.

Menu path (example for MIUI): Settings → Battery and performance → Application selection → Mi Fit → No restrictions

If the bracelet shows the wrong time or date, check the time zone settings in the application. Usually, time synchronization occurs automatically when connected to the phone, but a network time failure on the smartphone can transmit incorrect data to the tracker.

Make sure that the bracelet fits tightly to the skin and is 1-2 cm above the wrist bone. If the skin is cold or damp, dry it and warm it up. Also check if the optical sensor on the back panel is dirty - wipe it with a soft cloth.
