How to connect your phone to Xiaomi TV via Bluetooth

Today’s users often have to stream content from their smartphone to the big screen, and wireless technology makes it as convenient as possible. Connecting the phone to a Xiaomi Mi TV or Redmi Smart TV via Bluetooth gives them access to audio management, file transfer and use the gadget as a remote. While many are used to using Wi-Fi for mirroring the screen, it is Bluetooth that ensures the periphery works smoothly without the need for complex routing.

However, it is important to make it clear that Bluetooth in Xiaomi TVs is primarily designed to connect audio systems and input devices, not to broadcast a high-resolution video stream. If your goal is to bring a game or movie image in 4K, it is better to consider Miracast or DLNA technology. However, for listening to music through external acoustics or connecting a keyboard for typing, this protocol is ideal.

In this article, we will take a closer look at the algorithm for pairing different devices, look at the nuances of the Android TV and PatchWall operating system, and provide solutions for common errors. You will learn how to turn your smartphone into part of the smart home ecosystem, managing a media center with minimal delays.

Preparation of devices for pairing

Before setting up, make sure both devices are in good condition and ready to be detected.The Bluetooth module of the Xiaomi TV is usually active by default, but in some versions of the firmware it is required to be enabled manually through the settings menu.The smartphone must also have an activated visibility function so that the TV can recognize it in the list of available gadgets.

It is important to consider the distance between devices: for initial pairing, it is recommended to be no more than 1-2 meters from the TV. Obstacles in the form of walls or metal objects can significantly weaken the signal, which will lead to a timeout of the connection or the inability to find the device. Make sure that both gadgets have the latest system updates, as older versions of MIUI or Android may have vulnerabilities in the communication protocol stack.

💡

To speed up the search for devices, turn on the geolocation on your smartphone – in modern versions of Android, this is a mandatory requirement for the Bluetooth scanner.

Check battery power: The process of finding and installing handshake protocols can consume energy, though not as intense as video transmission. If the TV is running a PatchWall system, the interface may be slightly different from the standard Android TV, but the basic principles remain the same for the entire Xiaomi product line.

Step-by-step connection instructions through TV settings

The main way to set up is through the TV's system menu, you'll need a remote control to navigate the interface, and the algorithm is universal for most models, including the 4S, 4X and Master series.

First, go to the main menu and select the gear icon for the settings section, then find the wireless connection item, depending on the version of the shell, it can be called "Bluetooth", "Devices" or be entered in the subsection "Network and Internet".

Once the search mode is activated, the TV will start scanning the surrounding space. The view time of the pairing device is limited to 120 seconds, so you need to quickly perform actions on the smartphone. If the list of devices is updated slowly, try to exit the menu and repeat the login to restart the detection service.

• 📱 Press the button “Menu” on the remote and go to the Settings section.
• 🔍 Select Device and Connection (or similar in your version of the software).
• 📡 Find the Bluetooth bar and switch the switch to the "On" position».
• 🔗 Click “Add Device” and wait for your phone name to appear in the list.

Using a smartphone as a remote and keyboard

One of the most useful features of a Bluetooth connection is the ability to use the phone as an extended remote control. Unlike an infrared port, Bluetooth does not require line of sight and works over long distances, which is convenient in large living rooms.

When you connect the keyboard via Bluetooth, there is no need to enter text requests in YouTube or the browser using the on-screen keyboard of the TV, which is often inconvenient. HID-Human Interface Device, which transmits button presses in real time, is especially true for owners of TVs with minimalist remotes that do not have a full-fledged control. QWERTY-layout.

It is worth noting that the input lag of a Bluetooth connection is minimal, but it can vary depending on the load of the channel. If you plan to use the phone for games, broadcasting the image in another way, and the sound and control of the launch over Bluetooth, make sure that there are no active sources of interference in the 2.4 GHz range.

Telephone as a source, TV as a column

Often users want to use a powerful speaker system to play music or podcasts from their smartphone. Xiaomi TVs support an A2DP (Advanced Audio Distribution Profile) profile, which allows high-quality stereo sound to be transmitted, which turns the TV into a full-fledged Bluetooth speaker.

To implement this scheme, you need to pair it from the TV side, as described in the instructions above, but in the profile “Audiovod”. Once successfully connected, all system sound of the smartphone, including notifications and media files, will be redirected to the TV speakers. The sound quality depends on the codec: SBC and AAC are usually supported, while aptX is less common.

• 🎵 Make sure that the phone has a Media Audio switch activated in Bluetooth settings for connected TV».
• 🔊 Volume control can be done by both the phone buttons and the TV remote, but priority is often given to physical TV buttons.
• ⏸️ When an incoming call is made, the music on the TV is automatically paused, and the call can be received through the TV microphone if it is equipped with a camera or an external microphone.

It's important to understand that when you stream audio over Bluetooth, you don't have video content on your TV screen, you only have the audio track. This method is not suitable for synchronizing the image and sound in video files because of the desynchronization, and you'd better use Cast or HDMI.

Connection methods comparison: Bluetooth vs. Wi-Fi

Users often confuse the capabilities of different wireless interfaces. To avoid frustration, you need to clearly understand the technical limitations of each protocol. Bluetooth is a technology for transmitting small amounts of data or streaming audio with low bitrate, whereas Wi-Fi Direct and Miracast are designed for multimedia.

The table below provides a comparison of key characteristics that will help you choose the best way to connect for your tasks. Pay attention to bandwidth: 4K video requires a channel width that Bluetooth cannot physically provide.

If you want to show photos to friends, Bluetooth will do well, although the transfer speed will be slow, but to run games or watch movies from your phone to your TV screen, using Bluetooth protocol is technically impossible in direct form; this is where casting mechanisms using Wi-Fi modules come into force.

The solution to the problem: the TV can’t see the phone

Despite the standardization of technology, users often find themselves in a situation where devices can't find each other. One common reason is to caching old pairing profiles. If you've previously connected this phone or another device with a similar name, the TV may be trying to use old encryption keys.

💡

The first step in any communication problems is to completely clean the list of conjugated devices on both gadgets and reboot the communication modules.

It’s also worth checking if the limit of connected devices is exhausted. Some Xiaomi TV models allow you to keep up to 7-10 devices in memory, but only 2-3 can work at the same time. Disabling unused peripherals, such as gamepads or old headphones, can free up resource for a smartphone.

• ❌ Go to Bluetooth settings on TV, find your phone in the list and select “Forget” or “Delete».
• 🔄 Perform a full reboot of the TV by disconnecting it from the network for 30 seconds (reset residual current).
• 📶 Make sure the phone doesn’t have Power Savings mode on, which can limit background Bluetooth scanner performance.

⚠️ Warning: If the problem persists after resetting your network, check if you have an antivirus or firewall application on your phone that blocks device detection.

In rare cases, the problem lies in the incompatibility of Bluetooth versions. Older phones with version 4.0 and below may not work properly with the new 5.0 modules in TVs, although backwards compatibility should provide basic functionality. USB-Ports may contain patches to improve compatibility.

Data security and confidentiality

When connecting a personal smartphone to a TV, especially at a party or public place, it is important to keep security in mind.The Bluetooth protocol is susceptible to a number of vulnerabilities, such as Bluejacking or Bluesnarfing, although they are closed in modern versions of Android and Android TV.However, leaving the device in visibility after use is not recommended.

When pairing devices, they exchange access keys. If you connect your phone to someone else's TV, make sure that after the session you delete the connection profile on both devices, which will prevent automatic connection in the future and access to media history or the ability to control your device.

⚠️ Note: Never accept requests for file transfer (OBEX) The TV can become a gateway to malware if you allow access to the file system without the need to.

For corporate use or in smart offices, it is recommended to set up guest profiles or use temporary ones. PIN-codes to pair, if such a function is supported by installed control applications, this adds an additional layer of verification and protects against unauthorized access to the media center.
