How to connect Xiaomi TV to your phone via Bluetooth

═══

Modern multimedia systems allow you to turn the living room into a real entertainment center, and the key element here is often a bundle of smartphones and TVs. Users of the Xiaomi ecosystem often wonder about the possibility of wireless data or sound transmission using Bluetooth. It is a really convenient protocol for connecting the periphery, but its functionality in the context of phone-TV interaction has its own unique features and limitations that you need to know about.

Unlike Wi-Fi Direct or Miracast, which are designed to broadcast images, Bluetooth is primarily focused on audio streaming and input devices. When you try to connect an Android smartphone and a Mi TV, you most often set up the phone as a Bluetooth headset for a TV or use reverse circuitry to output sound. Understanding this connection architecture will help avoid frustration and set up the system correctly.

In this article, we will discuss in detail the pairing algorithms, possible use cases and methods for solving typical problems. It is important to understand that standard Bluetooth is not designed to transmit high-resolution video in real time, so expectations need to be built around audio and control. We will look at how to make your smartphone part of a home audio system or remote control using only built-in communication modules.

Features of Bluetooth Protocol in Xiaomi TVs

The Bluetooth technology in Xiaomi TVs is implemented with an emphasis on the stability of the connection with peripherals, unlike smartphones, where Bluetooth is used for file transfer and tethering, in the case of the Internet. TV-Android-based systems TV or PatchWall, this module most often works in reception mode (A2DP Sink) or output (A2DP This means that the TV can either receive sound from the phone or transmit it to wireless headphones.

It's worth noting that the bandwidth of the channel is limited. If you plan to use a bunch to listen to music, the quality will depend on the codecs supported. Current Mi TV Stick and Mi Box models support aptX, which provides high audio quality, whereas budget models can be limited to a standard SBC codec. This is not critical for management, but it matters for audiophiles.

⚠️ Attention: Do not attempt to use Bluetooth to stream video from your phone to your TV. channel bandwidth (around) 2-3 Mbit/s) is categorically insufficient for the transmission of a video stream even in low resolution, which will lead to desynchronization or break of the connection.

It is also important to consider the module version: new TV models are equipped with Bluetooth 5.0 and higher modules that provide longer range and less power consumption. Older models can have version 4.0 or 4.2, which sometimes causes compatibility problems with the latest smartphones, although backward compatibility is usually maintained at a basic level.

To check the Bluetooth version and signal quality on the Xiaomi TV, you can use the application "Bluetooth Analyzer" from the Google Play Store, installed on the device. TV-prefix.

Preparation of devices for pairing

Before you start looking for devices, make sure both gadgets are ready to go. On a Xiaomi TV, the Bluetooth module by default can be turned off or hidden in the depth of the menu. You need to go to Settings, select Remotes and Accessories (or Remote & Accessories) and activate the search. The interface may vary depending on the version of the PatchWall shell.

On the smartphone, you should also enable visibility for other devices. In some versions of MIUI or HyperOS, Bluetooth settings can be optimized to save energy, which hides the device from external search. It is recommended to open the Bluetooth settings and make sure that the Visibility slider is activated. Also, make sure that both devices have updated software to the latest version.

• 📱 Make sure that your smartphone and TV are no longer a distance away. 3-5 Meters apart for a stable primary handshake.
• 🔋 Check the battery level on your mobile device, as active search and pairing can quickly drain energy.
• 📡 Turn off Bluetooth on other nearby devices to avoid confusion when searching for and selecting the wrong gadget from the list.

If you are using the external TV-A set-top box, such as the Mi Box S, make sure it's connected directly to the TV and not closed by the TV case, which can shield the signal. USB-port, so the presence of metal objects in the immediate vicinity can impair the quality of communication.

Instructions: Connecting a smartphone as an audio device

The most common use case is to output sound from the TV to the phone (using the phone as a headset) or vice versa. For the first option, when the TV transmits sound to the phone, the process is as follows. Go to the Bluetooth menu on the Xiaomi TV via the Settings path → Remote and accessories → Add accessories.

When you start the search, you'll see a list of available devices on your TV screen, find your smartphone name in the list and select it. You'll see a request for a matching code on your mobile device, you'll need to check the numbers and confirm the action on both screens, and after you've successfully paired, the sound from the TV will go through the phone's speaker or the headphones connected to it.

The activation menu path:


Settings → Remote and accessories → Add accessory → Search → Selection of devices

The reverse is that when the phone streams music to the TV, you need to turn on the receiver mode on the TV. Make sure it is visible on the Bluetooth menu of the TV. On the phone, start searching for new devices, select your Mi TV and confirm pairing. After that, in the phone's audio settings, you need to select Xiaomi TV as the audio output device.

Using the phone as a remote control

While direct control via the standard Bluetooth HID (Human Interface Device) profile on Xiaomi TVs is not always explicitly implemented, there are effective ways to turn a smartphone into a remote.The official Mi Remote or Google Home app uses a local Wi-Fi network to transmit commands, but for devices without a screen or in specific Bluetooth scenarios can be used by system services.

If your goal is to control a media player, when you pair your phone with your TV as an audio device, you often see playback buttons (Play/Pause/Next) on your smartphone screen, a standard feature of the AVRCP protocol. It allows you to flip through tracks or pause videos without getting out of the couch using the phone's interface.

For more advanced management, including PatchWall menu navigation, it’s best to use dedicated remote emulator apps that can work hybridly: They try to establish a connection via Bluetooth Low Energy (BLE) for an initial handshake, and then switch to Wi-Fi. This ensures work even if the router is temporarily unavailable, but the devices are on the same subnet.

• 🎮 Use Google Home app for basic media content management on Android TV.
• 📱 Xiaomi Mi Remote app offers advanced functionality for smartphone owners of the same brand.
• ⌨️ Third-party Bluetooth emulators HID You may try to emulate the keyboard if TV Supports input from external keyboards.

File transfer and limited functionality

Users are often interested in the ability to transfer photos or video files directly over Bluetooth. In the Android TV operating system on which Xiaomi TVs are based, the standard OBEX (Object Exchange) profile responsible for transferring files is often disabled by the manufacturer or hidden, this is done for security and optimization of system performance.

If you try to send a file from your phone to your TV through the standard Share via Bluetooth menu, the TV may simply not appear in the list or the request will be rejected. In rare cases, on older versions of firmware or if you have specific file managers on the TV (for example, X-plore with a Bluetooth Server plugin), this can be implemented, but this is rather an exception.

To transfer media content, it is much more efficient to use DLNA or Chromecast technologies. They work on top of Wi-Fi and provide high speed transfer. Xiaomi TVs have built-in Chromecast support, which allows you to stream photos and videos from the phone gallery with a single touch, which is the preferred use case.

Solving Typical Connection Problems

Despite the standardization of protocols, users often face difficulties, and one of the most common problems is that the TV can't see the phone or vice versa, in which case you need to complete a full cycle of rebooting modules, not just turn off and turn on Bluetooth, but actually forget the device in the paired list and remove it from the cache.

If the pairing is gone but the sound is missing or interrupted, check the power saving settings. On Xiaomi smartphones with MIUI shell, aggressive battery optimization can kill the data transfer process in the background. Add the app through which the broadcast is being streamed to the exclusion list or set the No Limits mode.

⚠️ Warning: If previously connected devices stop working after upgrading your TV firmware, reset your network settings. Often new security certificates block old encryption keys.

Also worth noting is the interference on the air. Bluetooth is running at 2.4 GHz, which is heavily loaded in apartment buildings. Microwave ovens, Wi-Fi routers and other gadgets running nearby can create interference. Try to move the router away from the TV or switch it to channel 1, 6 or 11.

💡

In 90% of cases, connection problems are solved by completely cleaning the list of conjugated devices on both gadgets and rebooting them.

Alternative methods of wireless interaction

Because Bluetooth is limited, other technologies are worth considering to make full use of the smartphone-television bundle. Cast (Chromecast built-in) is native to Android TV. It allows you to stream your phone screen, videos from YouTube, Netflix and other applications directly to the large screen with minimal latency.

Another powerful tool is the Mi Home app or Xiaomi Home. If your TV is integrated into the smart home ecosystem, you can control it remotely, check status, run content, and even use the phone as a touchpad to navigate the TV interface. This works over the cloud or local area network, regardless of Bluetooth.

For PC owners and advanced users, there is the option of using ADB (Android Debug Bridge) over Wi-Fi, which allows you to control the TV file system, install applications and debug processes directly from the phone using terminal emulators, but this method requires the inclusion of the developer mode in the hidden menu of the TV.
