And if you are planning to buy a new gadget, at the end of the article there is a table of compatibility of popular Xiaomi models with the latest versions of Bluetooth.

1. How to find out the Bluetooth version through MIUI settings (the easiest way)

This method works on all Xiaomi smartphones, including Redmi, POCO and Black Shark, regardless of the firmware version.

Open the Settings app (the gear icon on the home screen) and follow the following steps:

  1. Go to About Phone (or About Device on some models).
  2. Tapping on All Features (sometimes called General Information or Specifications).
  3. Scroll down to the Network and Communications or Wireless Networks block.
  4. Find the Bluetooth string – next to it will be a version (e.g. Bluetooth 5.2).

If you don’t have All Features on your menu, try an alternative path:

  • 🔍 Settings → Connections and sharing → Bluetooth → Click on the three dots in the upper right corner and select Additional.
  • 📱 On some firmware, the version is displayed in the Settings section → System system → Updating the system → Three points. → Version. MIUI (scroll down).

💡

If you only display "Bluetooth" without a version in the settings, it means your firmware is hiding this information. Try other ways from the article.

Verification of Bluetooth version via the engineering menu (for power users)

The Engineering Menu (or Engineer Mode) contains advanced hardware data, including a Bluetooth chip version, which is suitable for Xiaomi based on Qualcomm Snapdragon processors (most models) and some MediaTek.

Warning: Do not change other options in the engineering menu unless you are sure of their purpose!

⚠️ Note: On HyperOS devices (e.g. Xiaomi 14), access to the engineering menu may be blocked.

Instructions for Snapdragon:

  1. Open the Phone app and enter the combination: ##4636##.
  2. In the menu that opens, select Phone Information (or Phone Information).
  3. Scroll down to the Bluetooth block, and the protocol version and chip model will be specified (e.g. Qualcomm WCN6750, BT 5.2).

For MediaTek processors (e.g., in Redmi 12C or POCO M6 Pro):

  1. Enter # #36446337## (code may not work on new firmware).
  2. Go to the Connectivity section → Bluetooth.
  3. The BT Version line will include the version.
What to do if the engineering menu is not opened?
If the codes don't work, it means that the manufacturer has disabled access to the engineering menu in your firmware. Alternative options: 1. Use diagnostic applications (section 3 of this article). 2. Install custom recovery (TWRP) and check the version through adb (method 4). 3. On some devices, the engineering menu is available through the Mi Engineer Mode app (you can download on 4PDA, but you need an unlocked bootloader).

3. applications for checking the version of Bluetooth (without root)

If the standard methods didn't work, you can use third-party utilities, and we tested 10 apps and selected the 3 most reliable ones that accurately show the version of Bluetooth on Xiaomi:

  • 📱 AIDA64 — It shows not only the Bluetooth version, but also the chip model supported by the code (e.g. aptX, LDAC). Download to Play Market.
  • 🔧 DevCheck – Minimalist application with Hardware section → Bluetooth, where version and supported profiles are specified (e.g, A2DP, HFP).
  • 🛠️ CPU-Z — tab SOC It contains information about a Bluetooth chip (e.g. Broadcom). BCM4359, BT 5.1).

How to use (in the example of AIDA64):

  1. Install and open the application.
  2. Go to the Device section → Bluetooth.
  3. The Bluetooth version bar will specify the current version (e.g. 5.3).
  4. Pay attention to the supported profiles line – this will help you understand what features are available (for example, AVRCP for music management).
📊 How do you usually check the Bluetooth version?
Through MIUI settings
Engineering menu
Appendix side (AIDA64, DevCheck)
ADB teams
Never checked.

If the app shows Bluetooth 4.2, but you're sure your device is newer, update the firmware. Sometimes, after the MIUI update, the Bluetooth version is "swiped" again, and the settings display outdated data.

4. Check through ADB (for advanced users)

This method requires connecting the device to your computer and using Android Debug Bridge (ADB).It is suitable if other methods have not worked or you need the most accurate information about the Bluetooth stack.

The advantage of the method is that you will not only get a version of the protocol, but also detailed information about the chip, profiles and codecs that your device supports.

Instructions:

  1. Install ADB and Fastboot Tools on your computer.
  2. Turn on your smartphone to debug by USB (Settings → About Phone → MIUI version → Press 7 times on the line, then go back to Settings → Additional → For Developers).
  3. Connect the phone to the PC and type in the command line:
adb shell dumpsys bluetooth_manager

In the conclusion, find the lines:

  • mAdapterProperties – there will be a version (for example, here, bt_version: 5.2).
  • mRemoteDevices – a list of connected devices and their versions.

For more detailed information, use the command:

adb shell dumpsys bluetooth_manager | find "version"

Install ADB on PC

Enable debugging over USB on Xiaomi

Connect your phone to the original cable

Start the command line on behalf of the administrator

Check that the device is determined (adb device command)-->

⚠️ Note: On some Xiaomi firmware (especially Chinese ones), dumpsys command may be limited:

adb shell settings get global bluetooth_version

5. How to find out the Bluetooth version on Xiaomi smartwatches and fitness bracelets

Xiaomi’s smart devices — Mi Band 7/8, Xiaomi Watch 2 Pro, Redmi Watch 3 — also have a Bluetooth module, but it’s harder to check than on a smartphone. Here are 3 working methods:

  • 📄 Official documentation: Find a model of your device on mi.com in the specifications section. S3 Supports Bluetooth 5.2.
  • 📱 Application Mi Fitness/Zepp Life: Open the app and go to the device profile. Tap the gear icon. Scroll to the Software section, sometimes it's a Bluetooth version.

Through a smartphone

  1. Connect your watch/bracelet to your phone.
  2. Open Settings → Connections → Bluetooth.
  3. Find your device in the list and click on the gear next to it.
  4. Some MIUI firmware displays a version of the protocol here.
  5. 🔧 Hardware failure: If the version hasn't changed after all the manipulations, the Bluetooth module may have been damaged.

If you’re planning to buy new wireless headphones or speakers, look for codes that are supported. For example, to listen to high-resolution music (Hi-Res Audio), your Xiaomi must support LDAC or aptX HD, which is only possible with Bluetooth 5.0+.

Why are my new headphones not working well with my Xiaomi?
If your headphones support aptX Adaptive or LC3 (the new codec for LE Audio) and your phone only SBC, you'll hear audio delays and poor quality Solutions: 1. Buy headphones with AAC support (works well with Xiaomi). 2. Use a Bluetooth 5.2 adapter (like Creative BT-W5). 3. Update your headphones and phone firmware to the latest versions.

FAQ: Frequent questions about Bluetooth on Xiaomi
