Modern Xiaomi and Redmi TVs are no longer just devices for receiving an air signal. These are full-fledged multimedia centers based on the Android TV operating system that require high-quality and uninterrupted peripheral connectivity. One of the key interfaces for expanding functionality remains Bluetooth, which allows you to transmit audio stream or control the cursor without unnecessary wires. Users often look for ways to bring sound to external acoustics or connect wireless headphones so as not to disturb others with volume.
The process of synchronizing devices in the Xiaomi ecosystem is usually intuitive, but there are nuances that depend on the firmware version and TV model. MIUI for TV or pure Android TV can have differences in the location of the menu. In this article, we will discuss in detail the algorithm of actions that will help you avoid common pairing errors. You will learn how to properly activate visibility mode and what to do if the TV does not find your gadget.
Before you go to settings, make sure your connected device is charged and in good condition. Wireless communication is sensitive to interference, so it is recommended to keep gadgets at a distance of no more than 3-5 meters from each other during the initial setup. This will provide a stable signal and fast connection establishment. Next we will go to the direct instructions for activating the module.
Activation of Bluetooth module in the system
The first step is always to turn on the wireless module itself in the settings of the TV, which can be turned off by default to save resources or because of the regional settings. You need to access the main control menu. To do this, take the remote control and find a button with the image of the gear or the settings icon.
After you go to the menu, navigation is done using the direction buttons. The interface may differ depending on which shell is installed: PatchWall or standard Android. TV. In most cases, the path is as follows: → Devices and accessories → Bluetooth. If you use older versions of the software, the path may be Settings. → Network and connectivity → Bluetooth.
The screen will have a switch that you want to activate. Once you put it on, the TV will start scanning the surrounding space. The device search usually lasts about 10-15 seconds. At this time, the system updates the list of gadgets available for connection. Make sure that the TV shows the "Search..." or similar activity indicator.
⚠️ Note: If the TV immediately shows a blank list after turning on Bluetooth, do not rush to restart the system. Often, it takes a few seconds for the module to initialize detection services, especially if a different connection profile was previously used.
Importantly, some Xiaomi TVs have a built-in module, but it can be software-disabled in certain regions.If you don't find a Bluetooth item on the menu, you may need to change your region in settings or upgrade your firmware to the current version.
Why is Bluetooth not on the menu?
Connecting wireless headphones and speakers
The most common use case is an audio output connection, which allows you to listen to music or watch movies at night without creating noise, first you need to put your headphones or speakers in pairing mode, usually by pressing the on button or a special button with a Bluetooth image for 5-7 seconds, until the indicator flashes quickly in blue or red and blue.
Go back to the list of available devices on your TV screen. The "Available Devices" list should show the name of your headset. It can show as a model (e.g. Mi True Wireless Earbuds) or as a generic name (e.g., "Wireless Headset"). Click on the name with the remote to begin the mating procedure.
The system may request confirmation or PIN-The standard code for most devices is 0000 or 1234, but modern Xiaomi devices support the Secure Simple Pairing protocol, which allows you to connect without entering code, simply by confirming the action on the screen. After successful connection status will change to "Connected", and the sound will automatically switch from the TV speakers to the external device.
☑️ Checking before connecting audio
If the audio doesn't go, check the audio output settings. Go to Settings → Sound → Output and make sure your Bluetooth device is selected, not Dynamics TV. Sometimes the default system continues to broadcast the sound through the built-in speakers, ignoring the active connection.
💡
To minimize latency when watching video via Bluetooth, use aptX Low Latency codecs if both devices support them.
Use of gamepads and keyboards
Xiaomi TVs turn the living room into a gaming area, especially if you use cloud gaming or emulators. Connecting a game controller is not much different from the audio setting, but has its own stability features. Gamepads, keyboards and mice use an HID (Human Interface Device) profile, which requires a more stable connection than audio streaming.
To connect the gamepad, turn it into search mode. On the screens of some emulators or games, you may need to calibrate the buttons. Once you connect to the Devices and Accessories menu, a new input device will appear. Android TV system perfectly recognizes standard controllers from Xbox, PlayStation (via an adapter or natively in new versions) and specialized gamepads for TV.
When using a wireless keyboard, it is important to consider that it can conflict with the remote if both devices are trying to control the cursor at the same time. In special features settings, you can turn off control of the cursor from the remote, leaving it only for the keyboard, which will eliminate the chaotic movement of the pointer on the screen.
| Type of device | Bluetooth profile | Features of connection | Signal delay |
|---|---|---|---|
| Headphones | A2DP / AVRCP | Automatic sound switching | Medium (notable in games) |
| gamepad | HID | Requires calibration in games | Low (critically) |
| keyboard | HID | Could be in conflict with the remote. | Minimum |
| sundbar | A2DP | Manual activation in the sound menu is required | High (not for games) |
Keep in mind that multiple Bluetooth devices can be intermittent, and if you have both a keyboard and headphones on, the radio can be overloaded, causing interruptions, and in such cases, it is recommended to use one of the devices via a wired USB interface if possible.
Solving the visibility problems of devices
Xiaomi TVs simply can't see Bluetooth devices are one of the most common situations, which can be caused by a cache of system services or a software failure of the module. First of all, try rebooting the TV by completely disconnecting it from the network for 10-15 seconds, which will clear the temporary files and restart the drivers.
The second important aspect is the forgotten devices, and if you've connected this headset or column before, but you're not connecting, find the device in the "My Devices" list, select it, and click "Forget or Disable." After that, search again. Old communication profiles often conflict with new pairing attempts.
⚠️ Warning: Make sure your Bluetooth device is not currently connected to your smartphone.Many gadgets automatically connect to the latest known device, becoming invisible to the TV.
The problem can also be in distance and interference. 2.4GHz Wi-Fi routers can interfere with Bluetooth because they use a similar frequency range. Try moving the router away from the TV or switching the Wi-Fi network to 5GHz if your router and TV support this standard, which will free up the air for stable wireless interface operation.
In rare cases, network resets help. Go to Settings → System → Reset and select resetting your Wi-Fi and Bluetooth settings. This won't delete your apps, but will return network settings to factory values, which often resolves software conflicts.
Adjusting sound and delays
Once a headphone or speaker is successfully connected, users often experience audio and video dissynchronization. Sound can be a fraction of a second behind the picture, which is especially noticeable when watching dynamic scenes or playing. Android TV has built-in compensation mechanisms, but they don't always work correctly.
To minimize delays, go to Settings → Sound → Additional settings. There may be a "Game Mode" or "Low Lag" option, activating this mode prioritizes transmission speed over quality, which reduces buffering, but the sound quality may deteriorate slightly.
If you use third-party video playback apps like VLC or MX Player, check their internal settings. They often have the ability to manually adjust audio delay (Audio Delay), you can move the slider a few milliseconds forward or backward, achieving the perfect lip of the actors in the words.
💡
Perfect synchronization of sound and image over Bluetooth is possible only with the support of both devices modern codecs with low latency.
Also worth paying attention to the equalizer settings: Some preset sound profiles ("Cinema", "Sport") can add digital processing that increases latency. Switching to "Standard" or "Direct" mode often eliminates the lags.
Expanded opportunities and limitations
While Bluetooth offers many possibilities, Xiaomi TVs, like any technology, have limitations: the protocol supports the simultaneous connection of a limited number of devices, usually a single pair of headphones or a single gamepad. Trying to connect two pairs of headphones simultaneously to watch a movie together is likely to fail without the use of special external transmitters.
The quality of the audio transmitted is also limited by the channel bandwidth. SBC, It's a device that supports all devices, but it's not a Hi-Res. For audiophiles, the built-in Bluetooth TV module may not be enough (S/PDIF) plug-in DAC-system.
Don’t forget about the Bluetooth version. Xiaomi TVs from different years of release can have modules version 4.0, 4.2 or 5.0. When connected to modern headphones with version 5.2, they will work, but only in compatibility with the older version of the TV. This means that you will not get all the benefits of the new standard, such as increased range or multi-stream.
