• 📱 Official ways to check through settings MIUI HyperOS
• 🔍 Hidden menus for advanced users (including: ADB and engineering menu)
• 📄 Database on Bluetooth versions for popular Xiaomi models

1. Verify Bluetooth version through MIUI/HyperOS settings

The easiest and safest way is to use the standard settings menu, which works on all Xiaomi devices running MIUI 12 and later, as well as HyperOS.

1. Open the Settings app (the gear icon on the desktop).
2. Go to the About Phone (or About the Tablet Device) section.
3. Tap on the item All characteristics (in some firmware it is called General Information).
4. Scroll down to the Network or Wireless Networks block – there should be a Bluetooth version string.

If you have HyperOS, the path may be slightly different:

Settings → About phone → Specifications → Wireless networks

⚠️ Note: On some devices (especially budget ones, such as Redmi) 9A or POCO C31) The Bluetooth version may not appear in this menu, so move on to the next method.

Update the firmware to the latest version

Try an alternative method through the "Developer Mode"

Check the model specifications on the official Xiaomi website

Use third-party applications (see Section 3)

2.Use of Developer Mode (for experienced users)

If the standard settings don't show the Bluetooth version, you can turn on the developer mode and find the information there. This method works on 90% of Xiaomi devices, but requires a few additional steps.

First, activate the developer mode:

1. Open the Settings. → The phone.
2. Find the MIUI Version line (or HyperOS build number) and tap it 7 times in a row.
3. Enter the screen unlock password if required.
4. You will be notified: You have become a developer.

Now go to the developer menu:

Settings → Additional → For Developers

Find one of the following items (depending on the model):

• 🔹 Bluetooth version (most likely)
• 🔹 Debugging by Bluetooth - in the description may be specified version
• 🔹 Bluetooth monitor (on some firmware)

💡 Useful tip: If the developer menu doesn’t have information about the Bluetooth version, try finding the Bluetooth Log line. HCI. When activating this option in the system logs (Settings) → System system → Logs) may appear with a module version.

3. Third-party apps to check Bluetooth version

If previous methods have failed, specialized utilities will come to the rescue, not only showing the Bluetooth version, but also providing additional information about the module (for example, supported codecs for headphones).-3 tested applications:

🔹 How to use: Once installed, open the app and find the Network or Bluetooth section. The version will be listed on the first line. AIDA64 The way is this: → Iron → Bluetooth.

⚠️ Note: Some applications (e.g. Bluetooth Scanner) may show a version of the connection protocol with the connected device rather than a version of your smartphone module. To avoid confusion, disable all Bluetooth devices before checking.

💡

If the app shows Bluetooth 4.0, but your smartphone is released after 2017, it’s probably a mistake.Try another app or check the model specifications on Xiaomi’s website.

4. Verification through the Engineering Menu (MTK and Qualcomm)

For advanced users, there is a way to learn the Bluetooth version through an engineering menu, which works on devices with MediaTek (Helio, Dimensity) and Qualcomm Snapdragon chips, but caution is needed – wrong actions can disrupt the module.

🔹 For MediaTek processors:

1. Open the Phone app.
2. Enter the code ##36446337## (or #4636### on some models).
3. Select MTK Settings → Bluetooth.
4. The BT Version line will include the version.

🔹 For Qualcomm Snapdragon processors:

1. Enter the code: ##2263###.
2. The RF Band Selection menu will open, and you can find information about the Bluetooth version.

⚠️ Note: Not all codes run on HyperOS – some engineering menus may be blocked. If nothing happens after you enter the code, don’t try again – this can cause the system to crash.

5.Apply through ADB (for tech-savvy)

If you're familiar with ADB (Android Debug Bridge), you can recognize the Bluetooth version using the command line, which is 100% accurate, but requires a connection to a computer.

🔹 Steps:

1. Enable USB debugging in the developer settings (see Section 2).
2. Connect your smartphone to your PC and open Command Prompt (or Terminal on Mac/Linux).
3. Enter the command: adb shell dumpsy bluetooth_manager
4. In the conclusion, find the line BluetoothAdapter.properties - there will be a version.

🔹 Alternative command: If the first one didn't work, try it:

adb shell getprop | grep bluetooth

Important: On some Xiaomi devices with HyperOS, the dumpsys command may be restricted for security reasons.

Frequent Mistakes and Myths About Xiaomi's Bluetooth Version

When checking the Bluetooth version, users often encounter inaccurate information or misconceptions, including the most common ones:

🔸 Myth 1: "If you don't have a Bluetooth version in your settings, you don't have one." Reality: The version can just be hidden in the firmware. Use alternative methods from this article.

🔸 Myth 2: "Bluetooth 5.0 is always better than 4.2." Reality: Newer versions provide better speed and stability, but are not always compatible with older devices. For example, headphones with Bluetooth 5.2 may not work well with a Bluetooth 4.0 smartphone.

🔸 Error: Confuse Bluetooth version with profile version (e.g, A2DP 1.3 or ) How to avoid: Profiles define functionality (e.g. music transfer or player control) and Bluetooth version defines hardware capabilities of the module.

🔸 Error: Reset your network settings in the hope of “updating” Bluetooth. Consequences: This will remove all stored Wi-Fi networks and Bluetooth devices, but will not change the module version.

💡

If you buy a used Xiaomi device, be sure to check the Bluetooth version. Many sellers keep silent that the smartphone only supports Bluetooth 4.0, making it incompatible with modern accessories.
