💡

If you’ve previously tried to connect other smart devices, clear the Bluetooth cache: Settings → Annexes → Application management → Three points. → Show system-based → Bluetooth → Warehouse → Clear the cache.

2.Select the app for connection: Mi Fit vs Zepp vs Wear OS

The right app is responsible for 80 percent of the success of the connection. Xiaomi and its subsidiary brand Amazfit use different platforms to manage the watch, and not all of them work equally well with the Redmi Note 8 Pro.

Main options:

For most Redmi Note 8 Pro users, the best choice will be Mi Fit (for Xiaomi watches) or Zepp (for Amazfit), except for the Xiaomi Watch. S3 And newer – they require Xiaomi Wear, which may not be installed on older versions. MIUI without circumventing regional restrictions.

Step 2: Preparing the clock

• ⚙️ Charge the watch to at least 50%
• 🔄 If the watch has already been connected to another device, reset via Settings. → System system → Reset
• 📱 Turn on the watch pairing mode (usually a long press on the physical button)

Step 3: Device pairing

Install and configure the application|Charge the clock to 50%+|Reset the clock (if used previously)|Insert the clock pairing mode|Add the device in the annex-->

1. In Mi Fit, press "+" → "Add the device" → Choose a watch model
2. On the smartphone will be a request to connect via Bluetooth – confirm
3. Compare the codes on the phone screen and the clock (must match)
4. Wait until the synchronization is complete (may take up to 5 minutes)

If at the interface stage there is an error "Can not connect", try:

• 🔄 Reboot both devices
• 📱 Manually add the clock through Settings → Bluetooth → Searching for devices
• 🛡️ Shut down. VPN Firewall (they can block the connection)

💡

For Amazfit models (GTR 4, GTS 4) be sure to use the Zepp app – Mi Fit does not support full functionality, even if the connection is successful.

4. Alternative ways of connecting: NFC and Wi-Fi Direct

• 📲 Wait for vibration and sound signal – this is a confirmation of successful pairing

Limitations NFC-linkage:

• ❌ It only works for the initial setup.
• ❌ Does not support constant data synchronization
• ❌ Requires a re-connection of Bluetooth for full functionality

Wi-Fi Direct (for firmware and large amounts of data):

1. In the watch app, find the Settings section → Update by air (OTA)
2. Connect both devices to the same Wi-Fi network (or use your smartphone’s hotspot)
