Technology has turned a simple video or music experience into a real multimedia experience, bringing together devices into a single ecosystem. Users often wonder how to connect a phone to a Xiaomi TV via bluetooth to bring sound to powerful speakers or stream content to the big screen. While Bluetooth wireless technology was originally designed to transmit data over short distances, in the context of smart TVs, it plays a key role in organizing the audio system.
One important technical nuance to note is that Bluetooth is not designed to stream live images from a mobile device to a TV screen in real time, as Wi-Fi Direct or Chromecast does. The main function of the connection in this case is to create an audio channel that allows you to use the TV as an external Bluetooth speaker, or connect peripherals such as headphones and gamepads to the TV itself. Understanding this difference will help you avoid confusion when setting up your equipment.
In this article, we will take a look at all aspects of working with wireless interfaces on Xiaomi devices, including pairing algorithms, possible limitations and alternative methods of content transfer. You will learn how to properly activate visibility mode, which codecs are supported by the Android TV system and what to do if the device is not on the list of available.
Bluetooth technical features on Xiaomi TVs
Xiaomi TVs, which are based on the Android TV operating system or PatchWall proprietary shell, are equipped with a built-in Bluetooth module, which usually meets the standards of version 4.0 and higher. This module is responsible for stable connection with external devices, ensuring the transmission of audio stream with minimal delays. It is important to understand that the channel bandwidth is limited, so for high-definition video (4K HDR) this interface is not technically suitable, unlike Wi-Fi.
Audio codecs are critical to sound quality. Current TV models support advanced codecs like aptX, AAC, and SBC that allow you to transmit sound with minimal compression. If your smartphone also supports the same codec as your TV, you'll get the cleanest possible sound. However, if devices use different coding standards, the system will automatically switch to basic SBC, which can slightly reduce the quality.
⚠️ Note: Do not attempt to use Bluetooth to mirror the screen (image broadcasting). This is technically impossible due to low data rates.
In addition, the Bluetooth module in a TV can work in two modes: as a receiver (when the phone connects to the TV) and as a transmitter (when the headphones are connected to the TV). In the context of our topic, we are interested in the mode of the receiver, when the TV becomes the audio output for your smartphone, the stability of the connection depends on the firmware version and the distance between the devices.
Preparation of equipment for interface
Before you start the connection process, you need to make sure that both devices are ready to go. This is a basic step that is often ignored, which leads to search errors. Make sure that your smartphone and TV are on Bluetooth and it is active. On Xiaomi TVs, the management of this option is in the system settings.
It is also critical that both devices be in close proximity to each other. The optimal distance for initial pairing is no more than 1-2 meters. Obstacles in the form of walls or metal structures can significantly weaken the signal, especially if you use older versions of the protocol.
☑️ Preparation for connection
Another important thing is to check the list of devices already connected, so if your TV has been paired with another phone and is in range, it can automatically connect to it, ignoring your new request, in which case you need to temporarily turn off Bluetooth on a third-party device or remove the TV from its list of stored gadgets, which will free the channel for a new connection.
Step-by-step: connecting the smartphone to TV
Connecting your phone to a Xiaomi TV via Bluetooth requires you to perform sequential actions on both devices. First, you need to activate the visibility mode on the TV so that the smartphone can detect it. To do this, take the remote control and go to the main menu.
On the remote, click the settings button (usually indicated by a gear) or the Home button to call the Quick Access menu. From the list that opens, select Settings. Next, look for the Add Accessories or Bluetooth section, which can be in the Remotes and Accessories or Network and Accessories category depending on the MIUI TV firmware version.
In the Bluetooth menu, make sure the switch is in the On position. The TV will start looking for available devices, but in this mode it also becomes visible to external gadgets. Now take your smartphone. Go to Bluetooth settings, turn on the search and wait for the name of your TV (usually a model, for example, MI TV 4A or Android TV).
You can see a request on your TV screen to confirm your connection with or without a code. Use the remote to select Confirm or Pair. Once you have a successful connection, your smartphone will notify you that the audio will be played through a Bluetooth speaker. Now any sound made by the phone will be broadcast over the TV.
| Phase | Action on TV | Action on a Smartphone |
|---|---|---|
| 1 | Menu -> Settings -> Bluetooth | Settings -> Bluetooth -> On |
| 2 | Add Accessory mode | Searching for devices |
| 3 | Waiting for the request | Clicking on the TV name on the list |
| 4 | Confirmation (Referral) | Acceptance of the request |
💡
If the TV isn’t visible on the list, try restarting the Bluetooth module on your smartphone by turning it off and on again, or restarting the TV itself.
Customization of audio output and media content
Once paired successfully, it is important to properly configure the output priority. In Android on smartphones, connecting a Bluetooth device often results in an automatic audio stream switching. However, in some cases, the sound may remain on the phone and you will need to manually change the output device.
If you plan to use the TV as a speaker to watch videos from a gallery or listen to music through streaming services, make sure the player app supports external audio devices. Most modern applications, such as VLC, YouTube or Spotify, do this automatically. However, if you use specific file formats, a software decoder may be required.
To adjust the volume, use the buttons on the TV remote. Note that on some models, the volume of the Bluetooth input and the built-in TV tuner is adjusted separately. If the sound is quiet, check the volume level on the smartphone itself. Double adjustment (at the source and at the receiver) allows you to fine-tune the balance.

Solving Common Connection Problems
Despite the simplicity of the technology, users may encounter difficulties connecting. One of the common problems is that the device is found but the connection is not performed or immediately breaks. This is often due to a Bluetooth cache on a smartphone or a profile conflict. Try forgetting the device on your phone and starting the process again.
Another common situation is no sound after a successful connection, in which case, check if the TV is chosen as the default output device in the smartphone sound settings. Also make sure that the TV does not have Headphones Only mode or a similar limiter that can block the output of sound to speakers when an active Bluetooth connection is installed.
- 🔍 Device not found: Make sure the TV is in pairing mode (the indicator flashes or the screen says "Search"), not just on.
- 🔇 No sound: Check the mixer settings in Android, sometimes media sound and system sound are separated.
- ⚡ Intermittent sound: Remove sources of interference, such as a running microwave or Wi-Fi router operating at 2.4 GHz.
If problems persist, resetting the network settings on your TV can help. Go to Settings -> Network -> Network Reset. This action will delete all stored Wi-Fi passwords and Bluetooth pairings, returning the network modules to factory status. After rebooting, try connecting the devices again.
Alternative ways to broadcast content
While Bluetooth is great at transmitting audio, there are more efficient methods for streaming an image or video from a phone to a Xiaomi TV. The main standard for the Android ecosystem is Google Cast (Chromecast built-in), which allows you to stream high-resolution video directly over a Wi-Fi network without straining your smartphone processor.
To use Cast, make sure your phone and TV are connected to the same Wi-Fi network. In YouTube, Netflix or Chrome apps, click on the Wave rectangle icon (broadcast) and select your TV. The image will appear on the screen and the phone can be used as a remote control. This provides better picture quality and no delays compared to any wired or Bluetooth methods.
Another option is Mi Remote, or MIUI's built-in Translation (Cast), which allows you to duplicate your smartphone screen onto your TV. Unlike Bluetooth, it uses Miracast or Xiaomi's proprietary protocol, and activate this feature in the phone's notification curtain by selecting "Translation" or "Projection" and follow the instructions on the screen.
💡
For video transfer, always use Wi-Fi (Chromecast/Mi Play), and Bluetooth is reserved exclusively for audio or peripheral connection (gamepads, keyboards).
