Smart wearable devices have become an integral part of modern life, and budget ones M4 fitness bracelet gained popularity due to their accessibility and wide range of functions. However, for owners of devices based Android the initial setup of the gadget can cause certain difficulties, especially if you are encountering such devices for the first time. The pairing process requires not only that Bluetooth is turned on, but also the correct installation of specialized software.
In this article we will analyze in detail the entire algorithm of actions, from unpacking the device to full synchronization of health data. You will learn why the standard Bluetooth menu of your smartphone is not always suitable for connection, and what system permissions must be granted to the application for it to work correctly. We will also look at typical errors that occur when trying to connect M4 Band with a phone, and offer effective ways to eliminate them.
Proper setup at the start is the key to long and uninterrupted operation of your activity tracker. An incorrectly established connection may result in calls or messages not being received and heart rate data not being saved in history. Therefore, it is extremely important to follow the sequence of actions and pay attention to the nuances of the operating system of your smartphone.
Preparing the device and smartphone for pairing
Before you try to pair your gadget with your phone, you need to make sure it is ready to work. Often new devices are shipped with minimal battery charge, so the first step is to put M4 bracelet on charge. The indicator on the screen should light up to confirm that power has arrived. If the device is completely discharged, leave it on charge for at least 15-20 minutes before turning it on.
On the smartphone side, a number of preparatory measures are also required. Make sure that the module is Bluetooth activated and in visible mode. In modern versions of Android, starting from 6.0 and higher, Bluetooth scanning also requires enabled geolocation (GPS). This is a Google system security requirement that many users overlook.
⚠️ Warning: If your smartphone has power saving mode enabled, disable it before starting setup. Aggressive power saving algorithms may block background application processes, which will prevent the bracelet from successfully connecting.
Also, check the availability of free space on the internal storage of the phone. The synchronization application, although it does not take up many gigabytes, requires space for temporary files and a cache of workout data. Clearing the memory before installing the software will help avoid errors when downloading and unpacking installation files.
☑️ Ready to connect
Selecting and installing the right application
The key point in the setup process is choosing the correct software. For the model M4 application is most often used FitPro, however, depending on the specific revision of the bracelet firmware, other clients may be required, such as Yoho Sports or WearPro. Information about the required application is usually contained in the instructions included in the kit, or is displayed as a QR code on the screen of the device itself when turned on for the first time.
It is strongly recommended to download the application exclusively from official stores: Google Play Market for Android devices. Installing software from third-party sources may result in your device being infected with malicious code or syncing functions not working correctly. In the store's search bar, enter the name of the intended application and pay attention to the number of downloads and rating.
After installing the application, launch it and go through the registration procedure. You may be required to create an account by providing an email address or phone number. Some features, such as saving activity history to the cloud, are only available to authorized users. Do not skip this step, as it is necessary to link the device to your account.
If the QR code on the bracelet is not read by the phone's camera, try increasing the brightness of the smartphone screen and moving the camera closer, or enter the name of the application manually in the store search.
When you first launch the application, it will ask for a number of permissions to access the phone's system functions. It is extremely important to provide access to Bluetooth, geolocation, contacts and notifications. Without permission to access notifications, you will not be able to receive messages from instant messengers on the bracelet screen, and without geolocation, the jogging route tracking function may not work.
Pairing process through the app
Many users make the mistake of trying to connect the bracelet directly through the Bluetooth system settings in the phone menu. This is the wrong approach for devices like M4 Band. Pairing must occur strictly within the interface of the installed application. If you previously paired the device in your phone settings, be sure to click the “Forget device” or “Unpair” button to clear the connection cache.
Open the application and go to the section responsible for managing devices. Usually it is called Device, Device or has an icon in the form of a watch/bracelet in the bottom menu. Click the Add Device (Add device) button or the plus icon. The application will start the process of scanning the nearest available gadgets.
At this moment, make sure that the bracelet screen is active. If it goes off, touch the touch button on the body to wake up the display. The model name should appear in the list of found devices, for example M4 or a character set containing these letters. Click on the device name in the application list to begin the pairing procedure.
| Connection stage | User action | Expected result |
|---|---|---|
| Search for device | Pressing the scan button in the application | M4 appears in the list of available devices |
| Initiation of communication | Selecting the name of the bracelet in the list | Request to confirm pairing |
| Confirmation | Pressing the confirmation button on the screen bracelet | Vibration of the bracelet and success message in the application |
| Synchronization | Waiting for data transfer to complete | Displaying time and data on the M4 screen |
After selecting a device, a confirmation request may appear on the bracelet screen pairing with a check mark or button OK. Press the touch area of the bracelet to confirm. A successful connection is usually accompanied by a short vibration of the device and a change in the status in the application to “Connected”.
Setting up notifications and data synchronization
After successful connection, the main task is to configure the transmission of notifications. Go to the device settings inside the application and find the section Call Reminder or Notification Alert. Here you can choose which applications should duplicate their notifications on the screen M4. Popular instant messengers are usually available: WhatsApp, Telegram, Viber, as well as calls and SMS.
For this function to work on Android, you need to give the companion application access to “Notifications” in the phone’s system settings. The path to this menu may differ depending on the smartphone model, but most often it is located in the Settings → Applications → [Your application] → Notificationssection. Make sure that the switch for allowed access is active.
⚠️ Attention: On Xiaomi, Huawei and Honor smartphones with MIUI or EMUI shells, you must additionally pin the application in memory and allow autorun. Otherwise, the system will kill the application process a few minutes after the screen turns off, and notifications will stop coming.
Also in this section you can configure the time display format. You can choose 12-hour or 24-hour format, which automatically syncs with your phone settings. Test synchronization by sending yourself a test message. If it appears on your wrist, then the configuration is correct.
Why don’t I receive notifications from specific applications?
Some instant messengers have their own internal notification settings. Go to the settings of the messenger itself (for example, Telegram) and make sure that the “Mute” or “Hide content” mode is not set for important chats, since the bracelet may not duplicate silent notifications.
Calibration of the pedometer and health functions
To increase the accuracy of measurements, it is recommended to enter your personal data in the application. Go to your user profile and indicate your current height, weight, age and gender. These parameters are used by algorithms accelerometer to calculate step length and calorie consumption. Without this data, statistics will be averaged and less accurate.
The heart rate monitoring function in the model M4 works in automatic or manual mode. In the application settings, you can set the automatic measurement interval, for example, every 10 or 30 minutes. It is worth remembering that frequent measurements significantly increase the battery consumption of the bracelet.
If you plan to use the bracelet to track sleep, make sure that it fits tightly to your wrist during the night. The sensor should have good contact with the skin, but not overtighten the hand. Data on sleep phases will be available in the application in the morning after synchronization.

Some firmware versions support a sedentary lifestyle reminder function. If you sit for a long time without moving, the bracelet will vibrate, inviting you to warm up. This feature can be enabled or disabled depending on your preferences in the health settings section.
Solving common connection problems
Even if you follow all the instructions, situations may arise when the bracelet does not connect or constantly loses connection. One of the most common reasons is a Bluetooth version conflict. Make sure your smartphone has the latest system updates. Sometimes resetting the phone's network settings helps clear Bluetooth stack errors.
If the application sees the bracelet, but when you try to connect it gives an error, try deleting the application, rebooting the phone and installing the software again. Also check if the bracelet is connected to another phone at the moment. M4, like most budget trackers, can only maintain an active connection with one device at a time.

Most connection problems can be solved by completely reinstalling the application and clearing the Bluetooth cache in the smartphone settings.
Recommendations for operation and updating
For stable operation, regularly check for firmware updates in the application. Developers periodically release patches that correct synchronization errors and improve the performance of sensors. The update usually occurs automatically when the bracelet is connected to a phone with active Internet, but the process can be started manually in the section Device Update.
Remember about the moisture protection of the device. Although M4 has protection against splashes and sweat, it is not recommended to immerse it entirely in water, especially in hot water or steam (sauna, bathhouse). High temperatures and pressure can damage the seal of the case and damage the electronics.
Wipe the strap and back of the sensors regularly with a soft cloth. Accumulation of sweat and dirt can irritate your skin and reduce the accuracy of your heart rate measurement. Following simple hygiene rules will extend the life of the accessory and ensure wearing comfort.
- 🔄 Regularly check the updates section in the application to install patches.
- 💧 Avoid contact with hot water and aggressive chemicals.
- 🧼 Clean sensors and sweat strap after each workout.
