How to turn Bluetooth on Xiaomi Smart Band 8: a step-by-step guide

Turning on Bluetooth on the Xiaomi Smart Band 8 isn’t just about activating a single feature, it’s about launching an entire ecosystem of interaction between your wrist and smartphone. Unlike the classic smartwatch, this tracker doesn’t have a full-fledged operating system with open access to network settings, which often causes confusion among beginners. In fact, the wireless module here runs in the background, waiting for commands from an authorized app to synchronize health data and notifications.

Many users mistakenly search for the switch in the menu of the bracelet itself, not realizing that the control of the radio module is completely left to the mobile application Mi Fitness. Bluetooth Low Energy (BLE), which is used in the device, consumes minimal amount of power, but requires strict adherence to pairing protocols. If you just unpacked the gadget or faced problems after updating the firmware, it is important to understand the logic of the system.

In this article, we’ll look at all the nuances of activating a wireless module, from the first couple to solving complex software conflicts, and learn why a standard phone settings menu may not see a device and how to properly configure permissions for stable operation.

Bluetooth in Smart Band 8

The wireless architecture in the Xiaomi Smart Band 8 is built on BLE technology, which is radically different from the classic Bluetooth used in headphones or speakers. The main difference is that the device does not constantly broadcast a signal for detection, but only periodically “wakes up” to check for requests from the smartphone. This allows battery life to last up to 16 days without recharging, which is a critical parameter for wearable electronics.

The control of this process is completely automated: once you open the application on the phone, it sends a request to wake up the tracker module. There is no constant Bluetooth active search on the bracelet itself, since this would instantly drain the battery, which is why you will not find the "Enable" button in the device interface.

For a stable connection, it is critical that the smartphone operating system versions and the bracelet firmware are compatible. Often problems arise from aggressive energy savings on Android smartphones, which can "kill" the application's background process by breaking the link with the tracker.

For maximum connection stability, add the Mi Fitness app to your smartphone’s power saving exception list.

Preparing the smartphone for the first pairing

Before you try to connect devices, make sure your smartphone is ready to work with the peripherals of Xiaomi.The process does not start with the bracelet, but with the setting of the mobile device, where all data and profile settings will be stored. Make sure that the phone has modern Bluetooth (preferably 5.0 and above) and geolocation services are activated.

Why GPS is required? Many users are surprised, but the BLE protocol uses location services to scan nearby devices at the Android and iOS system level. Without geo-positioning enabled, the phone simply won't start searching for new gadgets, even if the Bluetooth slider is active.

It’s also worth checking if your bracelet is connected to another phone.The Smart Band 8 can store multiple pairs in memory, but active sync only leads to one device. If the tracker was previously linked to another account, it should be untied through the app, rather than simply forgetting in Bluetooth settings.

• 📱 Make sure that the latest version of the Mi Fitness app is installed on the smartphone from the official store.
• 📍 Enable geolocation services (GPS) in the notification curtain or system settings.
• 🔋 Charge the bracelet to at least 20%, as at low charge the communication module can work unstablely.
• 🔄 Reboot your smartphone to reset possible Bluetooth stack errors.

Step-by-step activation instructions via Mi Fitness

The main and virtually the only way to “turn on” Bluetooth on the bracelet is to conduct the pairing procedure through the official application. The interface of the tracker itself does not provide manual control of the radio module, as this is done to simplify the user experience and protect against accidental changes.

Launch the Mi Fitness app and log in to your account (Xiaomi, Google or Apple). On the home screen, click Add Device or go to profile. The app will automatically start a space scan, at which point a vibration signal and a request for confirmation of pairing should appear on the bracelet screen.

Click on the confirmation icon on the tracker screen, and then you'll see a pair request on your smartphone, confirm it, and the system will automatically set up the necessary data exchange protocols, and the bracelet will go into active synchronization mode.

It is important not to interrupt the process when the original configuration files are transferred. If the screen goes out, tap it to activate it. In rare cases, you may need to re-click to confirm access rights to notifications and contacts.

Configuring permissions and system parameters

After successfully creating a pair, it is critical to properly configure the permissions, otherwise Bluetooth will be on but not work properly. Android operating system, in particular the MIUI shell and HyperOS, have strict background activity rules. If the application does not have full access, the connection with the bracelet will break when the phone screen is locked.

Go to your smartphone settings, look for the Apps section, and select Mi Fitness. Here you are interested in Permissions. Make sure that Bluetooth, location, and notifications are allowed at all times, not just when you're in use. This is a key point for background synchronization.

Also, consider the battery settings. In Activity Control, select Unlimited or Autostart, which will allow the app to keep the tracker channel open at all times, preventing the system from putting it to sleep to save charge.

Solving Device Detection Problems

There are times when Bluetooth is on, the app is running, but Xiaomi Smart Band 8 stubbornly does not appear in the list of available devices. Often this is due to the fact that the tracker is already “remembered” by the system, but the connection with it is lost, and it blocks new attempts to connect.

The first thing to do is go to the Bluetooth system settings of your smartphone, find your bracelet (usually called Mi Smart Band 8) in the list of previously paired devices, and click “Forget the device” or “Untie.” Only then repeat the search in the application.

If that doesn't work, try resetting the network settings on the smartphone itself, which won't delete your data, but will update the network stack, and it's also effective to reboot the bracelet itself through the settings menu or hold the touch button until the vibration appears.

⚠️ Warning: Do not attempt to connect to the bracelet directly through the phone's Bluetooth system menu without bypassing the app.This will result in a pairing error and the device will become unavailable for Mi Fitness until completely reset.

Features of working with several devices

Xiaomi Smart Band 8 supports multi-connect, but with limitations. It can be tied to one main smartphone for full data synchronization, but it can support a connection with another device for notifications (Android only).

If you want to switch the bracelet to a new phone, be sure to break the connection on the old device via the app.Just turning off Bluetooth on the old phone isn't enough - the bracelet will keep looking for a familiar device and ignore new requests.

For iOS users, there is a limitation: the bracelet can only be active on one iPhone at a time.Switching between iPhone and Android requires a full detachment and reconfiguration, as the structure of health databases in iOS and Android differs.

• 🔗 For full synchronization, use only one main device.
• 📲 Switching between phones requires a mandatory “Forget the device” procedure».
• ⚙️ The display notification settings are stored in the bracelet memory and can be reset when changing the platform.

💡

The main secret of stable operation is the correct permissions in Android and the absence of old “remembered” pairs in the Bluetooth system menu.
