Modern Xiaomi TVs running on Android TV or PatchWall offer a wide range of wireless peripheral connectivity capabilities. The Bluetooth feature in these devices not only allows you to transfer audio to wireless headphones, but also connect game controllers, keyboards and sound systems. Users often look for ways to improve their viewing experience by getting rid of unnecessary wires that spoil the interior and limit freedom of movement.
The synchronization process may seem complicated at first glance, but the interface of MIUI TV or standard Android TV is designed as intuitively as possible. Owners of Mi TV Stick, Mi Box and whole TV series Mi TV 4, Mi TV P1 or Mi QLED need to know the nuances of the communication module. In this article, we will discuss in detail all the stages of setting up, how to connect different types of devices and methods for eliminating common errors.
It is important to understand that the success of the connection depends on the software version and hardware capabilities of a particular module. Some budget models may have restrictions on the number of devices simultaneously connected or support only certain audio transmission profiles.
Verification of module availability and interface preparation
The first step before trying to connect any gadget is to verify that you have a built-in Bluetooth module in your TV model. Although the vast majority of modern Xiaomi devices have this module, some older or specific regional versions may not have it or may be software-disabled, and check through the system settings menu, where all available wireless interfaces are displayed.
To start the diagnosis, go to the system settings section. Usually the path is as follows: click the menu button on the remote, select the gear icon and go to Settings → Devices and Accessories (or Add Accessories). If you see a Bluetooth option or a list of previously connected devices in this menu, then the module is physically present and serviceable. Otherwise, if the option is missing completely, you may need to update the firmware or use an external adapter.
⚠️ Note: If the Bluetooth option is grey and inactive, don't rush to bring the TV to the service. Often this means that the module is temporarily disabled by the system due to energy saving or software reset. 1-2 minutes and then turn it on again.
Before you start searching, make sure that the device you are connecting (earphones, speakers) is in pairing mode. For most gadgets, this means that the indicator should flash quickly in blue or red and blue. Just turn on the device is not enough - it should be visible to other gadgets. If you are connecting the headphones for the first time, press the power button or a special pairing button before the characteristic signal appears.
Step-by-step instruction for connecting audio devices
The most common wireless scenario on a TV is the connection of headphones or a portable speaker system, which allows you to watch movies or play late night games without disturbing others with a loud sound. The pairing process on the PatchWall shell and pure Android TV has minimal differences, but the overall algorithm of actions remains the same for the entire Xiaomi ecosystem.
Follow the following steps to successfully synchronize:
- 🎧 Put your headphones or column into search mode (usually by holding the on button).
- 📺 On the TV remote, press the Home button and go to the top right corner to the gear icon (Settings).
- 🔍 Select Devices and Accessories, then click Add Accessories.
- 📡 Wait for the TV to scan the airwaves and select the name of your device in the list that appears.
Once the device is selected, a request for confirmation of pairing may appear on the screen. In some cases, you need to enter code that is often standard (for example, 0000 or 1234), but for modern Bluetooth 4.0/5.0 devices this is rarely required. Once the connection is established, the sound will automatically switch from the TV speakers to the connected gadget. In the upper right corner of the screen, the corresponding battery icon or connection status will appear.
☑️ Checklist of successful connection
And it's worth noting that when you connect Bluetooth headphones, the sound in the TV speakers is completely turned off, and this is the normal behavior of the system, designed to avoid echoes and conflicts of audio streams. If you want to stream sound to both headphones and speakers at the same time, you can't do this with standard means, you need special external transmitters or software crutches that can cause delay.
Connecting gaming controllers and peripherals
Xiaomi’s Android TVs are becoming powerful multimedia centers that do great with emulators and cloud gaming. For comfortable gaming, the built-in remote is often not enough, and users connect gamepads from Xbox consoles, PlayStation or universal controllers. The system recognizes them as standard input devices, which allows you to play most games from the Google Play Store.
The process of connecting a gamepad is similar to connecting audio devices, but has its own features in pairing mode. For example, for an Xbox One S or X controller, you need to press the pairing button on the end of the case until the logo flashes quickly. For DualShock 4, you need to hold the Share and PS buttons at the same time. Once the controller name appears in the list of available devices on the TV, just select it.
⚠️ Some cheap Chinese gamepads may not be correctly defined by Android TV, requiring the installation of third-party drivers or button mapper applications.
In addition to gamepads, you can also connect a Bluetooth keyboard and mouse to your TV, which makes it a computer-like experience, which is convenient for web surfing or document processing through office applications, a mouse allows you to control your cursor more precisely in the PatchWall interface, and a keyboard speeds up text input when you search for videos or Wi-Fi passwords. The connection is automatic, and after pairing, a cursor appears on the screen.

Use of Bluetooth adapters and transmitters
What if your Xiaomi TV model doesn't have Bluetooth built-in or it's out of order? In this case, external USB adapters or optical transmitters come to the rescue. However, it's important to understand the difference between the two. A regular USB-Bluetooth adapter for PCs (whistle) on Xiaomi TVs won't work without root rights and complex driver compilation, since the kernel of the system doesn't have the right modules for arbitrary chips.
The only working option to expand the functionality is a dedicated Bluetooth transmitter with a 3.5mm AUX or Optical (S/PDIF) connection interface, which takes an analog or digital audio signal from the TV and airs it to your headphones. They don't require drivers, because for the TV they're just external speakers. You plug a transmitter into the headphone jack, and wireless headphones into the transmitter itself.
The advantage of this method is versatility: it works even on the oldest TV models, as long as there is a sound output. However, there is a disadvantage - latency. When watching videos, actors' lips may not fall into the beat of their voice. To minimize this effect, choose adapters that support aptX Low Latency codecs or aptX Adaptive.
| Type of connection | Pluses | Cons | Sound delay |
|---|---|---|---|
| Built-in Bluetooth | No extra wires required, remote control | Limited radius, depending on the TV model | Low (100-200 ms) |
| USB-adapter) | Cheapness | It doesn’t work without root rights and drivers. | N/D |
| BT-Transmitter (3.5 mm) | It works on any TV, simplicity. | Need a separate charge/battery, possible delay | Medium/High (depending on the codec) |
Set up sound output and device management
Once a headphone or speaker is successfully connected, Android TV usually switches output automatically, but the user can manually control the process or adjust the audio settings for better quality, especially if you use high-quality acoustics and want to use the full capabilities of the Dolby Audio or DTS-HD sound engine.
To manage connected devices, go to Settings → Devices and Accessories. Here you will see a list of all the associated gadgets. By clicking on the device name, you can:
- 🔊 Change the priority of audio output (if multiple devices are connected).
- ❌ Disable the device without removing it from memory (convenient for temporary switching).
- 🗑️ Forget the device (complete removal of pairing information).
Some versions of PatchWall firmware have a Sound Mode feature where you can select presets like Movie, Music or News. When you connect a Bluetooth headset, these settings can be ignored because the audio processing is on the headphone side. However, it is worth checking the settings in Settings → Sound → Additional settings to make sure the output format is installed in Auto or PCM, which provides the best compatibility.
💡
If the sound in Bluetooth headphones is quiet, check the settings of a separate app (like YouTube or Netflix) as they may have their own volume control independent of the system.
Problem Solving: The TV cannot see the device
Despite the stability of Android TV, users often face a situation where the TV simply does not find the headphones or speaker. This can be caused by a software failure, overflowing with Bluetooth cache memory or interference in the air. First of all, try to restart the TV completely shutting it down for a minute. This clears RAM and restarts system services.
If the reboot didn't help, check the distance.The Bluetooth range in a walled room is rarely more than 8-10 meters.Make sure there are no powerful sources of interference between the TV and the device, such as a running microwave or a router running at 2.4GHz (although Bluetooth uses frequency hopping, dense Wi-Fi traffic can create problems).
Another common reason is a crowded list of paired devices.The Bluetooth module has a limit on the number of gadgets you remember.If you've previously connected many phones or speakers, remove old and unnecessary entries from the Add Accessory list.It also helps to clear the Bluetooth service cache through the developer menu, but it requires caution.
⚠️ Warning: Do not try to connect devices that are in the mode of another TV or phone. Bluetooth headphones often automatically connect to the last active device, becoming invisible to search by the new TV. Turn off Bluetooth on your phone before searching.
