Modern wearable gadgets have become an integral part of the digital ecosystem, and the model M16 Plus deservedly takes its place among the popular budget solutions. However, like any Wear OS or proprietary device, this watch requires proper initial setup to sync with your smartphone. The connection process may seem confusing due to the many similar models and applications, but in fact it consists of several logical steps.
Many users encounter difficulties precisely at the stage of choosing software, since the Play Market store offers dozens of analogues. Wrong choice of application This is the most common reason why the watch does not see the phone or does not transmit notifications. In this article, we will analyze in detail the algorithm of actions that guarantees a successful pairing between your gadget and smartphone.
We will also touch on the technical nuances of the operation of Bluetooth modules and explain why the standard Android settings menu is not suitable for full integration of accessories. You do not need to be an IT expert to set up the device, just follow the sequence of actions described below.
Preparatory stage before pairing
Before trying to connect the devices, you need to make sure that both gadgets are in working order and ready to interact. Charge M16 Plus watch to a level of at least 50%, since the process of initial setup and firmware update may require significant energy consumption. A dead battery can lead to a loss of connection at the most critical moment.
Enable the module Bluetooth and geolocation (GPS) on your smartphone. This is a mandatory requirement for the Android operating system from version 6.0 and higher. The system uses location services to scan for available Bluetooth devices, and without active GPS, searching for the watch will be unsuccessful.
⚠️ Attention: If you have previously paired other smartwatches or bracelets, be sure to go to your phone's Bluetooth settings and tap "Forget device" or "Unpair" for older gadgets. An address conflict may prevent a new connection.
Make sure the watch's screen is on and in pairing standby mode. Usually, when turned on for the first time M16 Plus they automatically switch to this mode, displaying a QR code or Bluetooth icon. If the screen goes dark, simply touch it or press the side button to activate it.
☑️ Ready to connect
Selecting and installing the right application
The key element of the ecosystem is a specialized companion application. For the model M16 Plus the main and most stable application is Da Fit. It is through this app that health data is transferred, dials are set up and notifications are managed.
Open the Google Play store on your smartphone and enter the name “Da Fit” in the search. Download the application developed by Shenzhen Jieshun Science and Technology Industry Co., Ltd. Avoid installing dubious clones with similar names, as they may not support the full functionality of your watch.
If you cannot find the application in the Play Market due to regional restrictions, scan the QR code displayed on the watch screen when you turn it on for the first time. It will take you to the download page for the required software version.
After installation, launch the application. You will need to create an account or log in through an existing account (Google, Facebook or email). Registration is necessary to save statistics of your activity in the cloud, so that the data is not lost when you change your phone.
Give the application all requested permissions. In particular, permissions to access contacts, SMS, call log and notificationsare critical. Without granting these rights, the watch will not be able to display incoming messages and calls, turning into a regular accelerometer.
Pairing process via Da Fit
The connection process itself is carried out exclusively within the application interface, and not through the standard Android Bluetooth settings menu. Open Da Fit and go to the “My” tab in the lower right corner of the screen.
Click on the item Add device (Add Device). The application will start scanning the air. Make sure the watch is close to the phone (within 1 meter). An entry M16 Plus or a code starting with the letters M16 should appear in the list of found devices.
Click on the device name in the list. The watch screen will ask you to confirm pairing with a check mark or confirmation button. Click on it. After this, a notification will appear in the app on your phone indicating a successful connection, and time and date synchronization will begin.
⚠️ Attention: Never try to pair directly through the Bluetooth settings on your phone. If you do this, the Da Fit app will not be able to establish a stable data connection and the watch will display as “connected but not synced.”
If scanning does not produce results for more than 30 seconds, try restarting Bluetooth on your phone: turn it off, wait 10 seconds and turn it on again. Also check to see if your phone has a power saving mode enabled, which may limit background scanning services.
Setting up notifications and health features
After successful pairing, you need to fine-tune your data transfer. Go to the Settings section inside the Da Fit application. Here you will find the “Message Notification” item. Activate the switches next to those applications whose messages you want to see on your wrist: WhatsApp, Telegram, Viber, SMS and calls.
For this function to work correctly on some smartphones (for example, Xiaomi, Huawei, Samsung), you need to additionally pin the application Da Fit in memory. Go to your phone settings, “Applications” section, find Da Fit and select the “Autostart” or “Run in background” option. This will prevent the system from being forced to close.
In the health monitoring section, you can configure the frequency of measurements. Pay attention to the table below, which describes the effect of sampling frequency on autonomy:
| Monitoring mode | Measuring frequency | Impact on battery | Data accuracy |
|---|---|---|---|
| Economic | Once every 30 minutes | Minimum | Low |
| Standard | Once every 10 minutes | Average | Optimal |
| Professional | Continuous | High | Maximum |
| Sleep | At night only | Low | High |
Also in this section you can set up a goal by steps, reminders about your sedentary lifestyle (sitting) and drinking regime. All these settings are synchronized with the watch instantly after pressing the save button.
Fixing common connection problems
Even if you follow all the instructions, technical failures may occur. One of the common problems is that the watch is visible in the phone’s Bluetooth list, but the application does not find it. In this case, you need to perform a complete reset of the watch. Go to the watch menu, find the item Settings (Settings) and select Reset (Reset).
Another common situation is a disconnection a few hours after setup. This is almost always due to Android's aggressive power saving policies. You need to add the application Da Fit to the battery exclusion list. The path usually looks like this: Settings → Battery → Battery optimization → All applications → Da Fit → Do not optimize.
⚠️ Attention: The energy saving settings interfaces may differ depending on the manufacturer of your smartphone (MIUI, OneUI, EMUI). If you cannot find the item you need, use the search inside the phone settings for the word “battery” or “energy saving.”
If the watch stops responding to touches or is stuck on the logo, perform a forced reboot. Press the side button (or the touch zone if there are no buttons) for 10-15 seconds until vibration or the logo appears.
What to do if the time on the watch is lost?
The time on the M16 Plus watch is synchronized only with a smartphone. If you see the wrong time, open the Da Fit app and pull down on the screen to force sync. Make sure that the correct time zone is set on the phone itself and that automatic time synchronization via the network is enabled.
Additional features and customization
Once the connection is established, access to advanced functions opens. There is a watch face store available in the Da Fit app. You can choose one of the preset options or upload your own photo. To set your own background, select the “Custom Dial” option, download an image from the gallery and press the download button on the watch.
The phone search function is also available. If you have lost your smartphone within the apartment, click on the phone icon in the watch menu. The smartphone will start to sound loud even if it is in silent mode. This is a useful feature for quickly detecting a device.
Do not forget to periodically update the watch firmware. Developers are releasing updates that correct errors in the heart rate monitor and improve the stability of the Bluetooth connection. A notification about the new version will appear in the application automatically.
The stability of the M16 Plus watch is 90% dependent on the correct power saving settings for the companion application in the Android system.
