Modern Xiaomi TVs, which run on Android TV, offer users a wide range of options for expanding functionality. One of the key wireless interfaces is Bluetooth, which allows you to transmit audio and data without unnecessary wires. Many owners purchase smart TVs precisely for the sake of using wireless acoustics or game controllers, but the process of initial setup often raises questions.
In this article, we will discuss how to activate the communication module, pair with external devices and solve typical problems that arise during operation, learn about the nuances of the protocol on the Android TV platform and get answers to complex technical questions.
Not all Xiaomi TVs have built-in Bluetooth, which is often a surprise for budget buyers. Before you start setting up, you need to make sure that the appropriate hardware is available in your particular device model.
Checking the availability of Bluetooth module on the TV
The first step before trying to connect any gadget should be the verification of the technical characteristics of your TV. In the line Xiaomi Mi TV and Redmi TV there are models where to reduce the cost of design, the manufacturer has excluded the Bluetooth radio module, leaving only Wi-Fi. You can check the presence of the module through the system menu or by examining the specification on the box.
The most reliable way is to go to the system settings and look for the appropriate section. If there is no "Bluetooth" or "Add Accessory" item on the menu, it is likely that the hardware is missing. Sometimes the module is there, but it is hidden or not activated software, which requires more in-depth analysis.
⚠️ Note: The absence of Bluetooth on the menu does not always mean that it is not physically available. In some regional firmware (for example, Chinese without global localization), this section may be hidden.
You also have to pay attention to the remote control. If the remote is running over Bluetooth (it has voice control or it works without the line of sight of the sensor), then the module in the TV is definitely there. If the remote is infrared (it requires guidance on TV), this does not guarantee Bluetooth for the periphery, but increases the odds.
- 🔍 Go to Settings. → Device and accessories and look for the Bluetooth section.
- 📦 Check the technical documentation or sticker on the back of the TV for the Bluetooth logo.
- 🎤 Check the type of remote: Support for voice input often indicates the presence of a radio module.
If you're convinced that a module is present, you can move on to directly activating and pairing devices, and ignoring this step can lead to a waste of time searching for a non-existent feature.
Bluetooth Activation and Device Search
The process of enabling the wireless interface on Xiaomi TVs is standardized, but may vary depending on the version of the PatchWall shell or pure Android TV. Usually all the necessary switches are in the upper right corner of the interface or in the deep settings menu.
To get started, you need to put the module into detection mode. The system will automatically start scanning the airwaves, but the success of the search depends on whether your peripheral device is in pairing mode. Just turning on your headphones or speaker is often not enough.
💡
Make sure that the device you are connecting is no more than 3-5 meters away from the TV and is not connected to another smartphone at this time.
Press the settings button (the gear icon) on the remote and go to Device and Accessories. Here you will see "Bluetooth." If the switch is turned off, activate it. The TV will start looking for available gadgets.
It's important to understand the difference between operating mode and pairing mode. The normal turn on of the headphones puts them in playback mode, and to connect to a new source (TV) you need to press a special button or hold the power button until the indicator flashes.
- 📱 Go to Settings. → Device and accessories → Bluetooth.
- 🔄 Make sure the activation slider is in the "On" position».
- 📡 Click Add Accessory to Start Forced Scanning.
If your gadget doesn't show up after 30 seconds, try rebooting the Bluetooth module on your TV by turning it off and on again.
Combination of headphones, speakers and gamepads
Connecting different types of devices has its nuances, although the overall algorithm remains similar. Audio devices (headphones, saunbars) and game controllers use different data transfer profiles, which can affect the stability of the connection.
To connect the headphones, select their name from the list of found devices on the TV screen. The system can request a pairing confirmation that must be received by the OK button on the remote. Once the connection is successfully installed, the sound will automatically switch from the TV speakers to the wireless headset.
☑️ Checklist of successful pairing
Gamepads like the Xbox Wireless Controller or Sony DualShock 4 connect in a similar way. However, for games, it is important to minimize signal latency. Some controller models may require a firmware update via PC before working with Android TV.
If you connect a Bluetooth adapter to transmit sound to an old speaker system (via AUX), make sure the adapter supports the A2DP Sink profile. Xiaomi TVs most often work as a source (Source), so the adapter must be able to receive the signal.
⚠️ Attention: When you connect Bluetooth headphones, the sound in the TV speakers completely turns off. To return the sound back, you need to manually turn off the headphones in the menu or turn them off.
In the case of keyboards and mice, the process is automatic, and a cursor can appear on the screen, controlled from the touchpad of the mouse, which turns the TV into a computer, which is convenient for surfing in the browser.
Set up audio output via Bluetooth
After successful pairing, it is important to properly configure the audio stream settings. Android TV lets you choose the default audio output device, but sometimes the system can get stuck on internal speakers.
To control the audio output, go to Settings → Sound → Audio output. You can force a Bluetooth connected device to choose from here, and you can also use the PCM (Passthrough) audio format settings in this section, which is critical for home theaters.
Why can the sound be quiet?
Sound quality is directly dependent on the codecs you support. If your headphones support aptX or LDAC, and your TV doesn't, the sound will be streamed in the SBC core codec. This is not critical for normal viewing, but audioophile can notice the difference.
In some cases, especially when using cheap Bluetooth adapters, audio and video (lipsync) may be desynchronized. To combat this, you can add artificial audio delay in the developer settings or special applications.
- 🔊 Go to Settings. → Calibration sound.
- ⚙️ Select the priority output device in the list of active connections.
- 🎚️ Adjust balance and equalizer to the characteristics of your wireless acoustics.
Remember that Bluetooth audio transfer consumes the resources of the TV processor, which in rare cases can affect the smoothness of the interface on weak models.
Use of Bluetooth adapters and transmitters
If there is no built-in module in the TV, or it does not work correctly, external solutions will be used. USB-Adapters: The market offers many options, but is compatible with Android TV — succession.
Most standard USB-Bluetooth whistles running on a PC won’t work on a TV without installing special drivers, which is extremely difficult to do on TV. You need to look for adapters that are defined by the system as HID (for keyboards / mice) or Audio device without the need to install software.
An alternative and more reliable option is to use an optical output (S/PDIF) or AUX with an external Bluetooth transmitter, which is powered by USB, receives digital or analog signals from TV and transmits them to any Bluetooth headphones.
💡
An external Bluetooth transmitter connected via optical output often works more stable and with less latency than embedded software solutions for budget TVs.
When choosing an adapter, look for the Bluetooth version. 5.0 and higher versions are relevant for TVs, providing better range and energy efficiency. Support for aptX Low Latency will be a huge plus for gamers.
Installation of such an adapter is simple: connect it to a USB port for power (if there is no separate power) and to an optical output for sound. The TV will “think” that the sound is output through the optics, and the adapter will instantly transmit it to the headphones.
Solving Typical Connection Problems and Errors
Despite the simplicity of the technology, users often encounter errors, the most common being “failed to conjugate” or persistent connection breaks, which can be caused by an ether overload or software failure.
Interference from a Wi-Fi router is a common cause of problems, as Bluetooth and Wi-Fi (2.4 GHz) are in the same frequency range. If the router is close to the TV, try to move it or switch the TV to a 5 GHz network.
| Problem. | Possible cause | Decision |
|---|---|---|
| No device found. | The pairing mode is not activated | Click the pairing button on the gadget until a quick blink |
| The sound is interrupted. | Wi-Fi interference or low charge | Charge the device, push the router away |
| Big latency of sound | SBC codec or distance | Use the LL adapter, shorten the distance |
| Driver error | Incompatibility USB-adapter | Use the transmitter via AUX/Optical |
Resetting your network settings can help if the Bluetooth software stack is “hanging.” In the settings menu, find “Reset Network Settings” or “Reset Bluetooth Preferences” that will delete all the saved devices and restart the service.
If nothing works, check for system updates. Xiaomi regularly releases patches that fix wireless modules. Go to Settings → About TV → System Update.
