Modern Xiaomi, Redmi and POCO smartphones are equipped with advanced wireless communication modules that ensure stable audio transmission of high quality. However, users often face a situation where automatic pairing does not occur, and the gadget simply does not see the headset. This may be due to the features of the MIUI or HyperOS shell, as well as the nuances of the operation of specific models of accessories. Understanding the algorithm of the system will avoid unnecessary reboots and time loss.
In this guide, we will go into detail all the steps of setting up, from putting the device in detection mode to fine-tuning the codecs for maximum sound quality. It is important to consider that the settings interface may vary slightly depending on the version of the operating system, but the overall logic of actions remains unchanged for all devices of the brand.
Incorrect sequences or ignoring simple diagnostic steps often lead users to think their technique is faulty, and in fact, 90 percent of the time, the problem is the trivial, unsynchronized status of visibility. Let's figure out how to make the connection fast and seamless.
Preparation of headphones for the first pairing
Before you try to find a device on the list of available devices, you need to make sure that it is ready to interact (ANC) When you first turn on, you automatically go to search mode, but old or discharged gadgets require forced activation. 5-7 seconds before the indicator flashes blue and red (or white.
If you TWS-The algorithm may be different, and often you need to remove both earbuds from the case and press the touch zones at the same time or hold the button on the case itself. It is critical that at this point, the headphones are not connected to any other smartphone that is nearby, as they can instantly βsnapβ the connection.
β οΈ Warning: If the light flashes quickly and intermittently, it almost always means low battery power.Put the headset on charge for at least 15 minutes, as in power saving mode, the Bluetooth module can work unstablely.
For NFC-enabled devices, the process can be simplified by simply putting them on the back of a smartphone if the feature is activated on the system. However, the classic method through the settings menu remains the most reliable way to initial register, especially for budget models where NFC-chip implementation is often absent.
Search and activation of Bluetooth on Xiaomi smartphones
The standard way to turn on the communication module is through the Quick Action Panel. Swipe down from the top edge of the screen to open the notification curtain, and find the Bluetooth icon. If the icon is grey, click on it to turn blue. For a deeper setup, you better press and hold your finger on the icon, which will immediately throw you into the corresponding system menu.
Alternatively, through the Settings app. Depending on the version of MIUI, the item you want can be in the Connection and Sharing section or be displayed in the main menu. After you log in, make sure that the Visibility for Other Devices switch is activated, although on modern Xiaomi smartphones it is on by default when the module itself is activated.
- π Click on the search icon or update the list if the device doesnβt appear immediately.
- π± Make sure your smartphone screen is unlocked, as for security reasons, finding new devices on a locked screen may be limited.
- π If the list is not updated for a long time, turn off and turn on Bluetooth again.
The system will start scanning the ether, and after a few seconds the name of your headset should appear in the list of "Available Devices". Please note that sometimes the device may appear under the technical code of the model, rather than under the commercial name indicated on the box.
Connection and confirmation of access rights
Once you see the name on the list, click on it. A pop-up will appear on your smartphone screen asking for pairing. In some cases, the system may request that you PIN-code, although it's rare for modern headsets. Standard combinations, if you need them: 0000 or 1234.
When you press the "Connect" or "OK" button, the system creates a secure communication channel, at which point the headphones may hear a voice message "Connected" or a characteristic beep. The status in the smartphone menu will change to "Connected" indicating the battery level, if the headset supports the transfer of this profile.
βοΈ Checklist of successful connection
Sometimes when you connect, the sound doesn't switch automatically, so you have to manually select the output device, unlock the screen, click the media control icon, or call the sound control panel and select your headset from the list of available sources.
Customization of sound and additional functions in MIUI
Xiaomi's ecosystem offers enhanced audio management capabilities. After a successful connection, go to the Bluetooth menu, click on the gear or arrow next to the device name, and it opens a menu of detailed settings where you can rename the gadget, turn off automatic connectivity, or view the charge level.
For users of Mi True Wireless or Redmi Buds headphones, it is recommended to install the Xiaomi Earbuds app (formerly Mi Buds M8), which allows you to update the firmware of accessories, adjust the equalizer, change the purpose of touch touch touch and select noise reduction modes. Without this application, many advanced features will remain unavailable.
β οΈ Note: Not all high-resolution codecs (LDAC, aptX HD) Supported by all Xiaomi smartphone models. Check the specification of your processor and Bluetooth module in the specifications on the official website.
In Settings β Sound and Vibration β Bluetooth sound quality (the path may differ in different versions of firmware), you can force the priority codec to be selected. If you are an audiophile, choose LDAC or aptX Adaptive for maximum detail. If stability of the connection in the subway or gym is more important, it is better to leave the standard SBC or AAC.
| Codec | Sound quality | Stability | Battery consumption |
|---|---|---|---|
| SBC | Basic | Tall. | Low. |
| AAC | Good. | Tall. | Medium. |
| aptX | Excellent. | Medium | Medium. |
| LDAC | Hi-Res (Maximum) | Low (depending on interference) | High-pitched |
Solving Common Connection Problems
It's a common situation where the phone sees a device but says "Didn't connect" -- most often because the headphones are "memorized" on another gadget and try to connect to it in the background -- the solution is one: go to Bluetooth on your phone, find your headphones, click on the gear icon and select "Forget the device" or "Cancel pairing."
Then do a full reset of your Bluetooth settings on your smartphone. Go to Settings β Connection and Sharing β Bluetooth, click three dots in the corner and select Reset Bluetooth. This operation will delete all previously saved devices, so they will have to be reconnected, but it often solves problems with the system's hanging services.
- πΆ Make sure there are no powerful sources of interference (wi-fi routers, microwave ovens) nearby).
- π Check if the headphones are power saving mode, if such a function is provided by the manufacturer.
- π² Reboot your smartphone is a banal but effective way to clear the cache of communication services.
If the problem persists with only one particular app (like YouTube), check the permission settings for that app. make sure it has access to the microphone and playback devices, although this is usually governed by Android system settings.
What to do if the sound is interrupted?
Use of the Engineering Menu for Advanced Users
For those who arenβt afraid to experiment, Android has a hidden engineering menu that allows you to manage Bluetooth settings at a low level. To get there, open the Phone app and type in the code ##6484## (for hardware testing) or ##4636## (for phone information).
Inside the testing menu, you can find the Bluetooth Test section, where commands are available to check the signal power and reboot the module without restarting the entire phone. This is useful if the standard slider on and off does not help. However, beware: changing unknown parameters can lead to unstable communication.
β οΈ Note: Signing into the engineering menu and changing the settings are done at your own risk.Do not change the values that are not sure, as this may affect the operation of Wi-Fi and the use of the system. GPS module.
Also in the "Developers" menu (to activate, you need to click on the build number in About Phone 7 times) there is the "Bluetooth AVRCP Version." If the music is not controlled from the headphone buttons, try changing the value from 1.5 to 1.4 or 1.6. This often solves problems with track metadata and switch buttons.
