Modern smartphones Xiaomi Redmi and POCO series are equipped with high-quality wireless modules that allow you to transmit audio stream without delay. Connecting external acoustics turns a mobile device into a powerful media center that can voice a party or become the basis of a home theater. The process of pairing in the shell of MIUI or HyperOS is as simplified as possible, but users often face nuances that require detailed explanation.
In this article, we'll look at not only the standard algorithm of actions, but also the hidden settings that affect sound quality. You'll learn how to properly activate visibility mode, which codecs support your devices and what to do if the gadget does not find the periphery. Connectivity depends not only on the drivers, but also on the correctness of the sequence of actions when the devices first meet.
Before we get to the practical steps, it’s worth noting that the menu interface may vary slightly depending on the version of the operating system. However, the logic of the Android system remains the same for all models. We will consider universal methods that will suit both the budget Redmi models and the flagship Xiaomi series.
Preparation of equipment and activation of search mode
The first and most critical step is to put portable acoustics into pairing mode, and many users mistakenly believe that simply turning on power is enough to detect the device by the phone, and in fact, the speaker should go into a special connection standby mode, often indicated by a flashing indicator or a voice message.
Usually, to activate this mode, you need to press the on button or a special key with a Bluetooth image for 3-5 seconds. If the indicator starts to flash quickly in blue (or alternately blue and red), this means that the detection mode is activated, at which point the device is ready to receive requests from external gadgets.
⚠️ Warning: If the indicator is on straight or flashing slowly, the device is likely just on but not in search mode. Repeat the button clamping procedure until the blinking pattern changes.
Make sure that the speaker is charged or connected to the grid. When the battery is low, some models automatically reduce the transmitter power or block the pairing to save energy.
Bluetooth configuration in the MIUI and HyperOS interface
Once the peripherals are ready, you need to move to smartphone settings. Xiaomi owners have two main ways to access wireless interface management. The first and fastest way is to use the control panel, which is called by swipe down from the top of the screen. The second way is through a full system settings menu.
For deep tuning, the full interface is recommended. Go to the Settings menu, find the Bluetooth partition, and activate the switch slider. The system will immediately start scanning the surrounding space for available devices, a process that can take anywhere from 5 to 15 seconds depending on the load of the air.
- 🔍 Device search: the smartphone automatically scans the air and displays a list of found gadgets in the section "Available devices".
- ⚙️ Visibility settings: Make sure your phone is also visible to others if you plan to transfer files, although it is not critical for audio.
- 📱 Identification: In the list, look for your column name, which usually corresponds to the model or brand listed in the instructions.
Just wait for the name of your acoustics to appear on the list.

The pairing process and confirmation of the connection
When the name of your acoustics appears on the list of available devices, click on it with one touch. The system initiates the handshake procedure, during which the encryption keys are exchanged. In most modern cases, especially with devices that support Bluetooth 5.0 and higher, the connection is instantaneous and without a request. PIN-code.
If the system requests a confirmation code, the standard value for most devices is the combination 0000 or 1234. This information is also always contained in the technical documentation for the column. After successful authentication, the icon of the connected device will appear in the status bar of the smartphone, and the color of the indicator will change on the column itself – it will become even light or go out.
| Status of indicator | Significance of state | User action |
|---|---|---|
| Fast blinking. | The mode of pairing (Pairing Mode) | Search for a device in the Bluetooth list |
| Slow blinking | Waiting for reconnection | Turn on Bluetooth on your phone |
| Smooth glow | Active compound | You can make sound. |
| Red color. | Low charge or error | Put it on charge. |
From the moment the Connected status is introduced, all system audio, including music, video and notifications, will be transmitted to an external device. If there is no sound, check the volume level on both the phone and the speaker itself, as they are independently adjustable.
💡
If after connecting, the sound goes through the phone’s speaker, tap the speaker icon in the notification curtain or lock screen and select your Bluetooth column as the output device.
Advanced sound and codec settings
For users demanding audio quality, Xiaomi offers access to hidden codec options.SBC's standard protocol provides basic quality, but modern devices support more advanced compression formats such as AAC, aptX or even LDAC.Using improved codecs allows you to transfer more details of the sound.
To check and change the codec settings, you need to activate the developer menu. Go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version). After the message "You became a developer" appears, go back to the main settings menu, select Additional → For developers.
In the list that opens, find the audio-related section, usually called the Bluetooth Codec, and you can choose the format that your speaker supports, and if you choose an incompatible codec, the connection may break or the sound may become intermittent.

Reproduction and multimedia management
Once successfully connected, tracks are managed using standard tools. The Xiaomi Redmi lock screen features a player widget with buttons for switching tracks, pauses and volume control. Most modern speakers also have physical buttons that duplicate these features, allowing you to control playback without removing the phone from your pocket.
Special attention should be paid to the speaker function, when an incoming call is made, the system automatically switches the audio stream to the speaker, turning it into a speakerphone. The speaker microphone tends to have better sensitivity and noise cancellation than the one built into the phone, which provides comfortable communication even in a noisy room.
In some scenarios, it is useful to use the Google Home app or the speaker manufacturer’s proprietary utilities (for example, JBL Portable or Sony Music Center), which allow you to customize the equalizer, update the acoustic firmware and create stereo pairs. For basic music listening, such applications are not necessary, but expand the functionality.
⚠️ Warning: If the connection breaks (out of range or discharge), the phone may not switch the sound back to the speaker automatically, in which case, just pause the playback and start again when the connection is restored.
Solving Common Connection Problems
Despite the technology's fine-tuning, users can run into difficulties. One of the common problems is that the phone sees the speaker but doesn't connect, giving an error called "failed to mate." In this case, cleaning the list of associated devices helps. Find the speaker name in the Bluetooth list, click on the gear next to it and select Forget the device or Unpatch the pairing.
Another common situation is intermittent sound or constant wheezing, which can be caused by interference from 2.4GHz Wi-Fi routers, or physical obstacles, try to keep your phone and speaker away from microwave ovens and routers, and check if too many background applications are running that consume CPU resources.
- 🔄 Resetting: Completely reset the column to factory settings (usually by pressing the volume and power buttons).
- 📶 Reboot: banal smartphone reboot often solves problems with the getting stuck Bluetooth module.
- 🔋 Power saving: Turn off the power saving mode on your phone, as it may limit the operation of wireless modules.
If neither method worked, perhaps the problem lies in the hardware compatibility of Bluetooth versions.Old speakers with version 2.1 or 3.0 may not work smoothly with the latest smartphones, although backwards compatibility should provide basic functionality.
💡
The most effective solution to 90% of connection problems is to completely remove the device from the phone’s memory (“Forget the device”) and re-pair the procedure from scratch.
