Modern wearable gadgets have become an integral part of digital health, and the model Intelligence Health Bracelet M3 is deservedly popular due to its accessibility and functionality. However, the process of initial device activation often raises questions among users who are encountering such technology for the first time. An incorrect sequence of actions can lead to the smartphone simply “not seeing” the tracker, despite Bluetooth being turned on.
In this article we will analyze in detail the pairing algorithm, which guarantees stable operation of the sensors and correct transmission of data about your activity. We will pay special attention to the settings Android systemsthat often block the operation of background applications, and also consider the nuances of choosing the right software. Understanding these technical points will allow you to avoid common mistakes and set up the device in a matter of minutes.
Preparing the device and smartphone for pairing
Before trying to create a pair between gadgets, you need to make sure that they are physically ready for work. The bracelet M3 often comes with a minimum battery charge, so the first step should be to connect it to a charger. The indicator on the screen must light up, confirming the receipt of energy, otherwise the module Bluetooth may not be activated at all.
On the smartphone side, it is also necessary to carry out preliminary “cleaning” in the communication settings. Go to the Bluetooth menu of your Android device and check the list of previously paired devices. If there is already an entry about M3 or a similar tracker from previous connection attempts, it must be deleted. This is a critical step, as a saved incorrect connection profile will prevent the establishment of a new, clean connection.
⚠️ Attention: Do not try to pair the bracelet directly through the standard Bluetooth menu in the phone settings. The device may appear in the list of available ones, but without a special application, full data exchange (steps, heart rate, notifications) will not work.
Also make sure that geolocation is enabled on your smartphone. In modern versions of Android, scanning for Bluetooth Low Energy (BLE) devices is technically tied to location permission. Without turning on GPS, searching for a device may be unsuccessful. Intelligence Health Bracelet M3, is technically tied to location access permission. Without GPS enabled, searching for the device may not be successful.
☑️ Ready to connect
Selecting and installing the right application
The key element of the ecosystem is software, which acts as an intermediary between the bracelet hardware and the phone's operating system. For the model M3 there are several firmware versions, so there may not be a universal application. Most often, manufacturers use the platform FitPro or Lefun Health, but the exact name is indicated in the instructions or on the QR code printed on the device body.
The application should be downloaded exclusively from official stores Google Play or App Store. Third-party resources may offer modified versions of software that contain viruses or do not work correctly with data transfer protocols. After installation, run the app and grant it all the requested permissions, especially access to notifications and background work.
Why does the application ask for so many rights?
Modern versions of Android strictly limit the operation of apps in the background to save battery. In order for the bracelet to receive notifications of calls and messages when the phone is locked, the application needs full access to the notification system and the right to run in the background without power saving restrictions.
If the kit came with paper instructions, scan the QR code with your phone's camera. This is the most reliable way to get to the desired download page. If you have lost the instructions, try entering the model name in the app store search. Sometimes manufacturers use brand names like WearPro or Da Fit for the same hardware platform.
The process of registering and searching for a device
After launching the installed application, you will be asked to go through the registration procedure. Although many functions are available without an account, creating a profile allows you to synchronize data with the cloud and not lose statistics when changing your phone. Enter the correct email address and create a strong password, as restoring access to health data may be difficult.
In the main menu of the application, find the section responsible for adding devices. It is usually indicated by a plus icon or the inscription Device / Device. Click the search button and the application will begin scanning the airwaves. At this moment, a vibration or Bluetooth icon may appear on the bracelet screen, indicating that it has been detected. M3 a vibration or Bluetooth icon may appear to indicate that it has been detected.
- 📱 Make sure that the bracelet screen is active at the time of the search.
- 📶 Keep the phone and tracker at a distance no more than 1 meter from each other.
- 🔄 If the search lasts more than 30 seconds, restart the application and try again.
Once the device appears in the list, click on its name to initiate pairing. A system window may pop up on your smartphone screen asking you to connect - confirm the action. The process of establishing a secure communication channel takes from 5 to 15 seconds, after which the time and date data are automatically synchronized from the bracelet.
Setting up permissions and background work
The most common problem of users is that the connection is lost a few hours after setup. This is due to Android's aggressive power saving policy, which kills processes not directly in use at the moment. In order Intelligence Health Bracelet M3 to work stably, you need to manually configure exceptions for the companion application.
Go to the phone settings, section Applications, find your application for the bracelet and open the “Battery” or “Energy Saving” item. Select mode “No restrictions” or “Do not limit”. This will prevent the system from disabling the application, even if the phone screen is off for a long time.
⚠️ Attention: There are additional levels of protection on Xiaomi, Huawei and Honor smartphones. Go to the “Security” application → “Permissions” → “Autorun” and allow the tracker app to launch manually.
It is also important to check permissions to access notifications. In the application settings, find the section Notifications and activate the switches for those instant messengers and services from which you want to see notifications on your wrist. Without this setting, the bracelet will vibrate only for incoming calls, ignoring messages from WhatsApp or Telegram.

Please note that support for older versions of operating systems may be formal. In practice, new versions of applications may not work correctly on Android 4.4 or 5.0 due to changes in Google security protocols. If you have an older device, you may need to look for an archived version of the application's APK file.
If the bracelet loses connection when you move more than 5 meters from the phone, check whether it is worn too loosely on your hand. Close contact with the skin improves the performance of the antenna and sensors.
Diagnostics and solutions to common problems
Even if all instructions are followed, technical failures may occur. For example, the bracelet displays the wrong time or does not count steps. In such cases, the first thing to try is to force sync by pulling down on the main app screen until the update indicator appears. This often solves the problem of time zone desynchronization.
If the device is not detected at all, perform a complete reset of the bracelet. In the menu of the tracker itself, find the item Reset or hold down the touch button for 10-15 seconds (depending on the revision M3). After rebooting, repeat the search procedure in the application. Also check if the “Flight” mode is enabled on your phone, which can block individual communication modules.
90% of connection problems are solved by completely removing the device from the phone’s Bluetooth menu and re-pairing exclusively through the app.
In rare cases, the problem lies in a conflict of firmware versions. Go to the application settings, section "About the device" or Firmware Update. If a new firmware version is available, be sure to install it without delay. Updates often contain corrections for connection protocol errors.
⚠️ Attention: When updating the firmware, the bracelet must be near the phone, and the battery charge must be at least 30%. Interrupting the recording process may lead to the device becoming bricked.
