Smart watch models M4 remain one of the most popular budget solutions in the wearable electronics market due to its affordability and wide range of basic functions. However, users often encounter difficulties during the initial setup, since the process of pairing these devices with the ecosystem Android has its own specific features that differ from standard Bluetooth gadgets. An incorrect approach to connection may result in the gadget being displayed in the list of devices, but not being able to transmit health data or notifications.
In this article, we will analyze in detail each stage of integrating the tracker into your system, starting with choosing the right software and ending with fine-tuning permissions for stable operation. You will learn why the standard Bluetooth menu is not suitable for full use of the watch and what hidden settings need to be activated in the operating system of your smartphone.
Preparatory stage and software selection
The first thing you need to do before attempting to synchronize is to make sure that your watch has enough battery power. It is recommended to charge the device for at least 30 minutes, since the initial initialization and firmware update process consumes a significant amount of energy. A weak charge can lead to a break in the connection at the most critical moment, which sometimes causes a software failure of the microcontroller.
The key element of the ecosystem M4 is a specialized mobile application through which all communication occurs. Unlike premium brands that use their own unique platforms, this tracker works through universal aggregators. Most often, an application is used for this model; however, depending on the batch and region of delivery, the manufacturer may bundle the device with software FitPro, however, depending on the batch and region of delivery, the manufacturer may complete the device with software Fundoo or WearPro.
To install the correct software, carefully inspect the device box or the back cover of the watch: there is usually a QR code there that leads to the download page on Google Play or the App Store. If the sticker is missing or unreadable, go to the app store and enter the model name in the search bar. Download only those apps that have high ratings and recent reviews from users who use similar gadgets.
Why can’t you use third-party applications?
Some users try to connect their watches through universal utilities like “Notify for Mi Band”. However, the M4 data transfer protocol is proprietary, and third-party software will not be able to correctly decode packets of information about heart rate or steps, which will lead to the display of incorrect data or a complete lack of synchronization.
After installing the application, do not rush to open it immediately. First, register an account using your email or phone number. This is a mandatory requirement of the server part of the service, without which local pairing by Bluetooth will be blocked at the software level.
The process of pairing devices through the app
Many users make a common mistake by first trying to find the watch in the Bluetooth settings of their smartphone. This approach is incorrect for this category of devices. The data exchange protocol requires that the connection be initiated strictly from the mobile application interface, and not from the phone’s system menu.
Launch the installed application and go to the device settings section, which is usually indicated by a clock icon or inscription Device. Click the search or add a new gadget button. At this moment, the smartphone screen will begin scanning the airwaves in search of signals with an identifier M4.
At the same time, a request to confirm pairing or a Bluetooth icon should appear on the screen of the watch itself, which will begin to blink. If this does not happen, try rebooting the tracker by holding the touch button for a few seconds until the logo appears.
- 📱 Make sure that the Bluetooth module on your phone is activated and visible to other devices.
- 📍 Turn on geolocation (GPS) on your smartphone, since in modern versions of Android this is a prerequisite for Bluetooth Low Energy to work.
- 🔋 Check if the watch is in power saving mode, which disables wireless modules.
When the application detects the device, its name will appear on the screen, often containing a set of symbols or letters M4. Click on it to begin the pairing procedure. The system may request permission to access geolocation and notifications - be sure to provide these rights, otherwise the functionality of the watch will be reduced.
☑️ Checklist for successful connection
Setting up permissions and background work
After successful pairing, it is critical to correctly configure the application permissions in the Android system. Modern smartphone operating systems, such as MIUI, OneUI or ColorOShave aggressive power-saving algorithms that can force background processes to close.
If the application is closed by the system, the watch will lose contact with the phone, stop receiving notifications about calls and messages, and synchronization of training data will only occur when you manually launch the software. To avoid this, you need to add the app to the battery exclusion list.
Go to Settings → Applications → FitPro (or your application) → Battery. Select the operating mode "Unlimited" or "Unlimited". This will allow the process to remain active in the background 24 hours a day, providing a stable communication channel with the wearable device.
⚠️ Attention: On some Xiaomi and Huawei smartphone models, you need to additionally fix the application in memory. To do this, open the menu of running applications, find the window with the tracker and click on the lock icon so that the system does not unload it when clearing the RAM.
Also check permissions to access notifications. In the application settings, find the section Push notifications and activate the switches for those instant messengers and services whose messages you want to see on your wrist. Without this setting, the watch will vibrate only when there is an incoming call.
Compatibility table and main characteristics
Understanding technical limitations will help you avoid disappointments with the functionality of the device. The model is positioned as a fitness bracelet with advanced capabilities, but it has a number of hardware limitations compared to full-fledged smartwatches. data-i="85">Bluetooth version M4 It is positioned as a fitness bracelet with advanced capabilities, but it has a number of hardware limitations compared to a full-fledged smartwatch.
| Parameter | Characteristics M4 | Android requirements |
|---|---|---|
| Bluetooth version | 4.0 / BLE | Android 4.4 and higher |
| Synchronization type | Only through the app | Availability of Google Play Services |
| Water protection | IP67 (splashes, rain) | Not recommended for swimming |
| Sensors | Pulse, steps, sleep | Access to motion sensors |
As seen from tables, the device requires a relatively recent version of the operating system for the correct operation of data encryption protocols. On older smartphones with Android versions below 5.0, the connection may be unstable or completely impossible due to the lack of support for the necessary libraries. BLE.
If you have a smartphone with two SIM cards, make sure that the application has access to call management for both lines, otherwise notifications about missed calls from the second SIM card will not be displayed.
Fixing common connection problems
Even if all instructions are followed, users may encounter a situation where the watch does not connect or constantly loses connection. One of the common reasons is the presence of an old pairing profile in the phone’s memory.
Go to the Bluetooth settings of your smartphone, find an entry with the name M4 or similar identifier in the list of devices and press "Forget device" or "Cancel pairing". Only after completely clearing the Bluetooth cache can you repeat the search procedure through the app.
Sometimes the problem lies in a conflict of firmware versions. The watch software update function may be available within the application. If the connection is unstable, try to find this item in the device menu and start the update by placing the phone and watch next to each other.
- 🔄 Restart both devices: the smartphone and the smartwatch.
- 📶 Turn off Wi-Fi during pairing to eliminate radio interference in the 2.4 GHz range.
- 🗑️ Uninstall and reinstall the application if the problem persists for a long time.
⚠️ Attention: Do not try to connect your watch to several smartphones at the same time. The M4 operating protocol does not support multi-connection. Trying to pair with a new phone without disconnecting from the old one will result in an authentication error.
Sensor calibration and personalization
After the technical connection has been established, you need to move on to personalization so that health data is as accurate as possible. Go to the user profile in the application and enter your real anthropometric data: height, weight, age and gender.
These parameters are used by algorithms to calculate step length and calorie consumption. Without precise input data, activity tracker will show average values, which may differ greatly from reality, especially when running or vigorous walking.
In the watch face settings section, you can choose the appearance of the screen. The application offers many options, from classic arrows to information displays with large numbers. Choosing a watch face that is too complex with a lot of animation may slightly increase the watch's battery consumption.
For sports fans, it is important to set targets. Set your desired number of steps per day and calorie limit. The watch will vibrate and light up the screen when you achieve your goal, acting as a motivator.
The accuracy of health data directly depends on the tightness of the strap to your wrist. A too loose fit results in loss of signal from the optical heart rate sensor.
