Xiaomi’s current smart TVs, which are powered by Android TV or PatchWall, offer users a wide range of multimedia capabilities. One of the key features that is often required for comfortable use is wireless audio transmission. This allows you to connect headphones for nighttime movie viewing or output audio to external speakers without unnecessary wires. However, the activation and configuration process of the module may vary depending on the firmware version and regional device model.
Many owners face a situation where the standard menu does not display obvious switches, or the device simply does not see the periphery, this is due to the fact that manufacturers sometimes hide advanced settings of radio modules to simplify the interface for the average user. In this article, we will discuss in detail all the ways to activate Bluetooth connections, from basic settings to advanced methods through the engineering menu.
In addition, we will look at the typical driver and codec compatibility issues that can occur when pairing with devices of different generations. Understanding the principles of wireless protocol in an Android TV environment will help you avoid common mistakes and quickly establish a stable connection between the TV and accessories.
Check Bluetooth technical support on your model
Before you start actively searching for devices, make sure your Xiaomi TV is physically equipped with a wireless module. Most current models, including the Mi TV 4, 4S, 4A, 5 and 5S series, have a built-in Bluetooth adapter that is also often combined with a Wi-Fi module. However, in some budget versions or older revisions, this feature may be missing or software disabled.
The easiest way to check for a module is to look at the device specification on the official website or in the instructions, and you can also try to find the relevant items in the settings menu. If there is no mention of wireless networks or accessories in the system, you may need to have a deeper diagnosis through system reports.
⚠️ Attention: Attempting to install Bluetooth drivers on a TV that does not have a physical module will not succeed and may lead to unstable system operation".
You can use a remote for quick checks. Many Xiaomi remotes have a button with a Bluetooth or microphone image that activates voice search. If voice search works without a USB keyboard connection, then the Bluetooth module in the TV is exactly present and functioning, since the Mi Remote remotes use this protocol to transmit commands.
Standard activation via the settings menu
In normal mode, PatchWall or pure Android TV provide a user-friendly interface for managing connections. To get to the desired menu, click the Home button on the remote and go to the top right corner of the screen where the gear icon is located. This is the entrance to the Settings section, where all the system parameters are concentrated.
Then the algorithm of actions may vary slightly depending on the version of the shell. In a classic Android TV, you need to select "Remotes and accessories" or "Add accessories." In the PatchWall interface, the desired section can be called "Bluetooth" or hidden in the submenument "Network and Internet", here you will see a list of available devices for connection.
☑️ Connection algorithm
Once you click the search button, the module will go into active broadcast mode, at which point a list of the gadgets found will appear on the screen, select the desired device from the list and confirm the pairing.
If the system requests PIN-The standard value is usually 0000 or 1234, and a successful connection will be accompanied by an audible signal and the device will appear in the Connected Devices list. From that point on, the sound can automatically switch to an external speaker if you plugged in the speaker, or stay on the TV if the gamepad is connected.
Use of the Engineering Menu and ADB for Advanced Users
Sometimes a software failure hides the standard Bluetooth interface, or the module is not working correctly. In such cases, debugging tools come to the rescue. To access advanced features, you need to turn on developer mode. Go to Settings → About device → Build and quickly click 7 times on “Assembly” until you receive a message that you have become a developer.
Once the developer mode is activated, a new section will appear in the settings menu called "Developers" where you can find USB debugging options and Bluetooth profile management, but the most powerful tool is the use of the ADB command line (Android Debug Bridge), which requires the TV and computer to be on the same Wi-Fi network.
adb connect 192.168.1.XX:5555
adb shell am start -a android.settings.BLUETOOTH_SETTINGSExecuting this command through a computer will force the Bluetooth system menu to open, even if it is hidden in the user interface, and this allows you to access a full list of functions, including resetting the pairing cache or forcing the module to restart. ADB You can check the status of service with the adb shell dumpsy command. bluetooth_manager, What is useful for diagnosing errors.
Risks of using ADB
It is worth noting that for the work ADB The TV should have the appropriate switch on the developer menu. If the TV is not visible on the network, check the settings of the router firewall or try to connect through the network. USB-cable, if the TV design allows access to the port.
Connecting different types of peripheral devices
The versatility of Bluetooth is the ability to connect a wide range of devices. The most common scenario for using Xiaomi TVs is the connection of wireless headphones. This allows you to watch movies late at night without disturbing your household. The TV automatically determines the profile of A2DP (Advanced Audio Distribution Profile) and directs the sound to the headset.
In addition to audio, you can connect game controllers to Xiaomi TV. Gamepads from Xbox, PlayStation (DualShock 4, DualSense) and various Bluetooth joysticks for smartphones are often defined by the system as standard input devices, which turns the TV into a full-fledged gaming console for emulators or cloud gaming.
| Type of device | Bluetooth profile | Features of connection |
|---|---|---|
| Headphones/Columns | A2DP / AVRCP | Possible delay of sound (Latency) |
| gamepads | HID (Human Interface Device) | Require calibration in games |
| Keyboards/Mouse | HID | Convenient for text input and navigation |
| Fitness bracelets | BLE (Low Energy) | Often require third-party applications |
When connecting keyboards and mice, it is important to consider that not all multimedia buttons can work correctly.Basic navigation and text input functions tend to work seamlessly, making it possible to use the TV as a desktop PC.Complex use cases may require the installation of additional drivers or button mapper applications.
💡
To minimize the latency of games, use headphones with support for the aptX Low Latency codec if your Xiaomi TV supports this standard.
Solving Typical Problems and Misconferences
Despite standardizing protocols, users often face problems, and one of the most common is that the TV can't see the device, even though it works on a smartphone, which may be because the periphery is already paired with another gadget and is in standby mode rather than in detection mode, and you have to force the device to Pairing Mode mode, usually by holding the on button or a special pairing button.
Another common problem is desynchronizing audio and video when watching movies through Bluetooth headphones, which is due to the way the TV transmits data over the air and the processing of the signal by the TV processor. In the audio settings (Settings → Sound → Advanced settings), you can try to change the sound modes or turn off additional audio improvements, which sometimes reduces latency.
⚠️ Note: If the TV stopped seeing any Bluetooth devices after updating the firmware, try resetting the network settings (not completely resetting the system.
Also worth mentioning is the problem of “disappearance” of the connection. If the connection is constantly broken, it is possible that the Wi-Fi module causes interference, since both radio interfaces operate in the 2.4 GHz band. In this case, it is recommended to switch the router to 5 GHz frequency or, conversely, to move the router away from the TV if the 2.4 GHz band is used.
Alternative ways to transmit sound without built-in Bluetooth
In the rare cases where the built-in module is faulty or missing, but you need to connect wireless acoustics, you can use external solutions. The easiest option is a USB Bluetooth adapter. However, Xiaomi TVs based on Android TV do not always have drivers for arbitrary whistles. Only specific models will work, often requiring root permissions to install drivers.
A more reliable way is to use an external transmitter that connects via optical output (S/PDIF) or a 3.5 mm connector (if any), called Bluetooth transmitters, which take an analog or digital signal from the TV and broadcast it to the headphones themselves, in which case the Bluetooth module of the TV does not use at all.
Another option is to use Chromecast built-in devices, which are found in most Xiaomi TVs. You can stream audio from your smartphone to your TV, and the smartphone, in turn, can distribute sound to its connected Bluetooth headphones (a feature is on some Android smartphones), creating a transmission chain.
💡
If the built-in module does not work, an external transmitter to optical output is the most stable solution for output of sound to wireless headphones.
