Modern wearables, such as Xiaomi’s popular trackers, have become an integral part of the active lifestyle of millions of users. However, despite the ease of use, sometimes there are situations when the gadget stops responding to commands or does not want to connect to the smartphone.
It is important to understand that smart bracelets do not always have a separate button to turn Bluetooth on the device’s menu, as many models rely on automatic activation when pairing. However, there are nuances of firmware and system limitations that require user intervention to restore a stable connection.
In this article, we will discuss in detail how to force a radio module to run, what applications are needed to control the device, and what to do if standard methods do not help, you will learn how to distinguish a software failure from a hardware failure and how to properly configure data synchronization.
The principle of Bluetooth in Xiaomi devices
The fundamental difference between fitness trackers and smartphones is the architecture of their operating system. Whereas on a phone you can manually switch sliders in the notification curtain, the Mi Band or Mi Smart Band often run in the background, waiting for a signal from the host.
Technically, the communication module in the bracelet constantly scans the air for a familiar MAC-It's a way of protecting the user from unauthorized access and keeping the battery in charge, and activating full detection mode only happens after a request is made through a companion app.
Why is the bracelet not visible when searching?
It’s worth noting that there’s a difference between “on” and “conjugated” states: A device may have an active radio module but not support connections if it’s already connected to another phone or blocked by Android or iOS system security settings.
Preparing a smartphone for pairing
Before you try to turn on Bluetooth directly on the wristband, you need to make sure that the receiving party - your smartphone - is ready to go. Often users try to find the device in the general settings of the system, which is a mistake.
First of all, check that not only is Bluetooth activated on the phone, but also geolocation. BLE (Bluetooth Low Energy) devices. GPS-The scanning gadget module just won’t start and you won’t be able to see your tracker.
- 📱 Open your phone settings and make sure Bluetooth is activated and visible to other devices.
- 📍 Turn on geolocation (GPS) and select High Precision Location Mode.
- 📲 Download the official Mi Fitness app (formerly Zepp Life) from Google Play or the App Store.
- 🔒 Give the app all the permissions you request, especially access to Bluetooth and background.
On newer versions of Android (12 and above), energy saving algorithms can aggressively kill background processes necessary to communicate with the bracelet, so it’s important to add the app to the battery exclusion list.
💡
Before you start setting up, clear the list of previously paired devices in your phone's Bluetooth settings. Delete all old Mi Band entries to avoid addressing conflicts.
Activation process through the Mi Fitness app
The main way to turn on Bluetooth on the wristband is to initiate the pairing procedure through official software, and it's the application that sends a special data packet that wakes up the tracker's radio module and puts it in visibility mode, which is often impossible to do on its own through the device's menu.
Launch the Mi Fitness app and log in to your account. On the home screen, click the add-on button. The system will automatically start scanning. At which point a pairing confirmation request may appear on the bracelet screen, which must be confirmed by touching the touch button or vibration.
If the automatic search didn't work, try the manual method. In the app, select the "Add device" option and wait for the list to appear. Sometimes you need to press and hold the touch button on the bracelet for 5-10 seconds to force the search mode to start, although in new models this happens automatically when you first activate.
If the process is interrupted at a stage of 50-80%, the Bluetooth module can freeze, in which case it will help to reboot the bracelet through the settings menu or application.
| Model bracelet | Bluetooth version | Annex | Features of connection |
|---|---|---|---|
| Mi Band 8 | 5.3 BLE | Mi Fitness | Fast pairing of NFC |
| Mi Band 7 | 5.2 BLE | Mi Fitness / Zepp Life | Support for AOD |
| Mi Band 6 | 5.0 BLE | Mi Fitness / Zepp Life | Classical conjugation |
| Mi Band 5 | 5.0 BLE | Zepp Life | Magnetic charging |
Solving the visibility problems of the device
The situation where the smartphone physically does not "see" the bracelet is one of the most common.This may be due to the fact that the Mi Band is already paired with another phone. Bluetooth protocol often does not allow the device to be visible to the third gadget while it is actively connected to the first.
To solve this problem, you need to break the existing connection. Go to the Bluetooth settings on your old phone, find the device and select "Forget the device" or "Unpair the pairing." Only then the bracelet will be available for search again.
⚠️ Attention! Do not try to connect to the bracelet directly through the Bluetooth Android or iOS system settings. This will lead to a pairing error. Initiation must occur strictly within the Mi Fitness or Zepp Life application.
It is also worth checking whether the bracelet is not enabled with Do Not Disturb mode or air mode (if the model supports independent communication, although this is rare for classic gangs), in some cases, resetting to factory settings helps, which completely clears the memory of the communication module of the old encryption keys.
☑️ Actions if the bracelet is not found
Resetting and reconnecting the tracker
If the software methods do not help activate the wireless module, you need to perform a full reset (Hard Reset), which will return the device to factory parameters, including Bluetooth settings, on most Xiaomi models, this can be done through the menu of the bracelet itself.
Swipe your finger across the screen before the settings menu (the gear icon) appears. Find System or Settings, then select Unbind or Factory Reset. Confirm action. Once the bracelet is rebooted, it will be ready for new pairing as a new device.
In the rare cases where the touch screen doesn't respond, you can use the app. In the Profile section, select your bracelet, scroll down and find the Unbind button. This will force you to break the connection and often restart Bluetooth services on the tracker itself.
💡
Completely resetting the device is a radical, but often the only way to restore the Bluetooth module to software failures.
Updating the firmware for stable operation
An outdated version of the software is a common cause of wireless modules that are unstable. Xiaomi engineers regularly release updates that fix bugs in the Bluetooth stack and improve compatibility with new versions of mobile OSes.
Check for updates in the app. If a new version is available, connect the bracelet to the charger (preferably above 50% charge) and start the process. During the update, do not disconnect the device from the phone or leave the application.
The firmware update rewrites the system files responsible for radio exchange. This can eliminate bugs that interfered with Bluetooth activation or caused permanent connection breaks. After the update, it is recommended to re-pair.
- 🔋 Make sure the bracelet is at least 50% charged before starting.
- 📶 Keep your phone and bracelet close to each other throughout the process.
- 🚫 Do not open other heavy apps on your smartphone during the upgrade.
⚠️ Attention! interrupting the firmware update process may cause the bracelet to stop turning on (brick.
