How to Connect Bluetooth to a Xiaomi TV: The Complete Guide

Smart TVs are no longer just devices for receiving an over-the-air signal. Xiaomi’s Mi TV and Redmi TV range offers multimedia capabilities comparable to powerful tablets. One of the key advantages of the Android TV or PatchWall platform is the presence of a built-in wireless module that allows you to transmit sound and data without unnecessary wires.

Connecting peripherals via Bluetooth opens up new use cases, such as watching movies at night without others, displaying sound on a powerful speaker system or using a gamepad for games. However, despite the apparent simplicity, the pairing process sometimes causes difficulties for users due to interface features or hidden system settings.

In this article, we will discuss how to activate the module, find the device and fix common connection errors. You will learn about the nuances of working with different versions of the operating system and understand why some gadgets are not visible to the TV. The key point is the version of Android TV: on old firmware, the menu may differ from the current interfaces of Google TV.

Preparation of equipment and compatibility check

Before you go to the menu settings, you need to make sure that your equipment is ready to go. Not all Xiaomi TV models have a built-in Bluetooth module, although in recent generations, the Mi TV Stick and Mi Box is almost always present. If you use a budget model with a PatchWall shell without Google certification, the presence of the feature is worth checking in the specification on the official website.

Make sure the connected device is in pairing mode.For headphones or speakers, this often means holding the power button or special Bluetooth catfish button for a long time until the indicator starts flashing quickly in blue or red.

💡

Keep your Bluetooth device no more than 1-2 meters away from your TV while searching and connecting to avoid data packet loss and sync failures.

It’s also worth checking the operating system version. Go to Settings → About TV → Version and make sure the software is updated to the latest available version. Older versions of Android TV may have bugs in the Bluetooth stack that have been patched in later security patches.

Standard Connection Procedure through Settings

The basic method of activating wireless communication is built into the system menu. The interface may vary slightly depending on the regional firmware (Global, EU, CN), but the logic of actions remains the same. You will need a remote control to navigate through menu items.

Go to the settings section by selecting the gear icon in the upper right corner of the main screen or by pressing the corresponding button on the remote. → Remote and Accessories: This is where you can control all of the external input and output devices.

From the menu that opens, select Add Accessory. The TV will start scanning the surrounding space. Once your device name appears on the list (such as AirDots or JBL Speaker), select it and press OK. The system can request confirmation with a code to enter or simply confirm the action.

Using a Hidden Engineering Menu for Advanced Search

The Android TV desktop interface sometimes hides devices that don’t fit the strict media profiles. If standard search doesn’t work, you can use system debugging tools or third-party utilities for deeper scanning, especially for older versions of Bluetooth (versions 3.0 and below).

One way is to use the Bluetooth Terminal app or similar scanning utility available from the Google Play Store on your TV, but a more advanced method involves using ADB (Android Debug Bridge) if you have access to your computer and command line skills.

adb shell am start -a android.bluetooth.adapter.action.REQUEST_DISCOVERABLE

This command forces the TV adapter to go into visibility mode for maximum time. You can also try to activate the developer mode. Go to Settings → About TV → Build and click on this item 7 times in a row. After the message "You became a developer", a new section will appear in the settings menu for developers, where you can turn on debugging over Bluetooth or change the audio transmission codec.

Connecting specific devices: headphones and gamepads

The process of connecting different types of peripherals has its own peculiarities: Bluetooth headphones usually work as a sound output device (A2DP profile), after connecting, the sound automatically switches from the TV speakers to the headset.

Gamepads are different. They are defined as input devices (HIDs). Xiaomi TV is great friends with Xbox One S controllers, DualShock 4 and specialized Android gamepads. Once paired in the menu Remotes and accessories, the device will appear as "Gamepad" or "Wireless Controller".

Game controllers may need to adjust the buttons further, as standard Android TV support doesn’t always correct all keys, and applications like Button Mapper help.

Problem Solving: The TV cannot see the device

The most common problem is that the device is not on the list of found devices. This can be because the Bluetooth module on the TV is “hanging up.” Simply shutting down the remote (which is often just a transition to sleep mode) does not restart the system completely. You need to perform a full reboot through the Settings menu → About TV → Reboot or physically turn off the power for 30 seconds.

⚠️ Warning: If your TV is connected to a 2.4GHz Wi-Fi network, it can cause severe interference to Bluetooth, as they work in the same frequency range. If possible, switch the router to 5GHz or blow the devices apart.

Another reason could be a crowded list of paired devices. Android TV has a limit on the number of gadgets saved. Go to the Bluetooth menu, find old, unused devices, and select the Forget or Disable option. After cleaning the list, repeat the search.

💡

Full reset (Hard Reset) by removing the power cord from the socket for 1 minute solves 80% of the problems with the invisibility of Bluetooth devices, resetting driver errors.

Customization of sound and elimination of delays

Once you have successfully connected your headphones or speakers, it is important to adjust the output. Go to Settings → Sound → Output and make sure that you choose a Bluetooth device rather than a TV Dynamics. In some versions of PatchWall firmware, this item may be hidden in the Advanced Settings submenument.

If you see audio and video desynchronization (actors' lips move before the sound goes), try changing the settings in the Settings for Developers section. Find a item related to Bluetooth buffering or codecs and try to change its value. Also, disabling additional audio enhancements like Dolby Audio or DTS, which can load the processor when transmitted over the air, helps.

For advanced users, a method of correcting the delay through ADB-commands that change buffering, but this requires caution. Standard system tools can only switch output modes (for example, from "Cinema" to "Sport" or "User"), which sometimes changes the algorithms for processing sound.

Use of external Bluetooth adapters

If the built-in module in your Xiaomi TV Is not available or is not corrected by external USB-However, not all adapters work with Android. TV. The system must have built-in drivers for the adapter chipset (most often these are chips). CSR, Realtek or Broadcom).

Connect the adapter to free USB-Go to the settings. → Remotes and accessories. If the system recognizes the device, you'll see a new Bluetooth adapter on the list. If nothing happens, the driver is probably missing. In this case, you can try installing the Bluetooth Auto Connect app from the app store, which sometimes takes control of the adapter, bypassing system restrictions.

It is worth noting that using cheap Chinese adapters with AliExpress often leads to unstable work, and it is recommended to look for adapters labeled "Plug & Play for Android TV Box".
