Modern wearables require the right initial setup to work properly. Xiaomi’s Haylou LS02 is stylishly designed and functional, but often raises questions for beginners when first launched. The process of creating a connection between the watch and the smartphone is not complicated, but requires a strict sequence of actions.
Many users make the mistake of trying to connect devices directly through the standard Bluetooth menu in the system settings, which is a wrong approach that will not allow you to activate all the capabilities of the activity tracker.
In this guide, we will take a detailed look at each step of pairing, from hardware preparation to fine-tuning notifications, and learn how to avoid common synchronization errors and ensure that your gadget works smoothly with your smartphone’s operating system.
Preparation for the first launch of the gadget
Before you start setting up, make sure your device is ready to go.The Haylou Solar LS02 comes with a base charge, but for confident synchronization, it's best to put it on charge for at least 15-20 minutes.This will eliminate a sudden shutdown at a critical time of firmware update.
Turn on the watch with a side button for a few seconds, and the brand logo should appear on the screen. QR-If the screen does not light up, check for protective film on the charging contacts on the back of the case - it must be removed before first use.
It's also important to prepare the smartphone itself. Make sure the phone has wireless modules on. Without active Bluetooth, you can't find the device (GPS), As the current versions of Android and iOS require location permission to search BLE-device.
💡
Before connecting, clear the list of paired devices in the phone’s Bluetooth menu from old “Haylou” or “LS02” entries if they are left behind from previous attempts.
Installation and configuration of the Haylou Sport app
The main management tool is the Haylou Sport app, which can be found in official Google Play stores for Android or the App Store for iOS. QR-The code displayed on the watch when turned on leads directly to the download page of the desired version of the program.
Once installed, start the app, you will need to register an account or log in through an existing profile (Google, Facebook), which is necessary to save your activity history in the cloud, and the first time you log in, the system will ask for a number of permissions.
For the correct operation of the smart watch Xiaomi Haylou LS02 you need to provide access to:
- 📍 Geolocation (required for Bluetooth scanner on Android 6.0)+)
- 📞 Contacts and call logs (to display the name of the caller)
- 💬 Notifications of messengers (WhatsApp, Telegram, Viber)
- 🏃 Fitness data (for synchronization of steps and pulse)
In the main menu of the application, go to the Profile tab or click on the add-on icon. The system will start searching for available gadgets within range. Make sure that the watch is near the phone (no more than 1-2 meters).
The process of pairing a clock with a phone
When the Haylou Sport app detects your watch, a device card called "LS02" or "Haylou Solar" will appear on your smartphone screen. Click on it to start the mating procedure. A request for confirmation of connection may appear on the watch screen - agree if it occurs.
The process of establishing a secure communication channel takes from 10 to 30 seconds, during which time do not switch between applications and do not block the phone screen. Once successfully connected, the watch will vibrate the status, and the main interface of the tracker will appear on the smartphone screen.
It is important to understand the difference between system Bluetooth and the application. The synchronization of time, date and weather data occurs exclusively through the Haylou Sport app, not through the standard menu of the phone settings. If the time on the clock is lost, then the background connection with the application is broken.
☑️ Checking a successful connection
Configure the language and interface of notifications
One of the first tasks after connecting is to localize the interface. By default, the watch can be in English or Chinese. To change this, in the Haylou Sport app, go to the device settings (cog icon or watch profile).
Find the "Watch Language" option and select "Russian" or "Auto." When you select the automatic mode, the watch interface language will mirror the language of your smartphone system. Changes apply immediately after confirmation.
To set up notifications, go to Push Notification, which lists all apps installed on your phone, and activate the switches in front of the services you want to see on your wrist:
- 📱 System calls and SMS
- 💬 Messengers (WhatsApp, Telegram, Viber, VK)
- 📧 Postal clients
- 📅 Calendar and alarm clocks
Please note that the notification text may not be displayed in full if the phone’s privacy settings hide the contents of the messages on the locked screen, in which case the watch will only show the name of the application.
⚠️ Note: On smartphones Xiaomi and MIUI You need to additionally fix the Haylou Sport app in memory and allow auto-run, otherwise the system will force the program to close, and notifications will stop coming.
Compatibility table and system requirements
The stability of the smartwatch depends not only on the correct configuration, but also on the version of the smartphone operating system. The Haylou LS02 model is based on the Bluetooth Low Energy protocol (BLE 5.0), which provides low power consumption, but requires support from the OS.
The following are the minimum requirements for the correct operation of all tracker functions:
| Parameter | Android | iOS (iPhone) | Note |
|---|---|---|---|
| Minimum OS version | Android 5.0 and higher | iOS 10.0 and higher | On older versions, the application may not be installed |
| Screen. | 720p and higher | Any authorization | The application interface is adapting |
| Bluetooth | 4.0 BLEs and higher | 4.0 BLEs and higher | Mandatory support for Low Energy |
| Memory. | 100 MB is free | 100 MB is free | For installation and cache of data |
If your smartphone meets these requirements but the connection fails, try restarting both devices. Often a temporary failure in the phone's Bluetooth stack prevents new devices from being discovered.
Why can't the watch see the phone?
Solution: if the connection fails
Despite the simplicity of the procedure, there are technical difficulties, and the most common problem is that the phone sees the device but writes "Pairing error" or "Unconnected." In this case, do not try to connect them through the standard Bluetooth menu.
You need to reset the pairing list completely. Go to your phone's Bluetooth settings, search for "LS02" or "Haylou" and click "Unpair/Forget" before repeating the connection procedure through the Haylou Sport app.
Another reason could be aggressive energy savings: Many smartphone makers (Huawei, Xiaomi, Samsung) limit the background activity of apps to save power, which causes the watch to fall off after a few hours of operation.
To prevent communication from breaking:
- 🔋 Turn off energy saving for Haylou Sport app
- 🔒 Allow auto-start and work in the background
- 📍 Make sure that access to geolocation is in "Always" mode"
⚠️ Note: When resetting the clock settings to factory (Reset), all accumulated statistics for the current day can be lost if synchronization with the server was not carried out.
💡
The key to stable operation is to allow Haylou Sport to run in the background without the limitations of energy saving.
