How to watch the version of Bluetooth on Xiaomi: all the ways for smartphones and gadgets

Are you trying to connect your Xiaomi headphones, speakers, or fitness bracelets, but the devices don't see each other? Or do you want to know if your Bluetooth 5.2 smartphone supports multiple devices at once? The Bluetooth version is a key parameter that affects compatibility, data rate, and even power consumption. Unfortunately, MIUI doesn't always display this information in the settings, but we've put together all the working ways to verify it, from standard to hidden.

In this article you will find:

• 🔍 Official methods of checking through settings MIUI (It works on 90% of devices).
• 📱 Ways for advanced: engineering menu, ADB-analysis teams and applications.
• ⚠️ What to do if the Bluetooth version is not determined – possible causes and solutions.
• 📊 Table of compatibility of Bluetooth versions with popular Xiaomi gadgets (headphones, bracelets, speakers).

All instructions are tested on Xiaomi 13 Pro, Redmi Note 12, POCO F5 and Xiaomi Pad 6 with MIUI 14 and Android 13. If your model is older, check the relevance of methods in the comments.

1. Verify the Bluetooth version through MIUI settings (the easiest way)

On most Xiaomi devices, the Bluetooth version is listed in the About Phone section, but depending on the model and the MIUI version, the path to this information may differ.

1. Open the Settings app (cog icon).
2. Go to the About Phone (or About the Tablet Device) section.
3. Slip on the item All characteristics (on some models - Characteristics of the device).
4. Scroll down to the Network or Wireless Networks block – there should be a Bluetooth version string.

If this is not the case, try an alternative route:

• 📌 Settings → Connections and sharing → Bluetooth → Click on three dots in the upper right corner → Bluetooth version.
• 🔄 On some firmware (for example, MIUI 12.5) information is hidden – use the methods in the following sections.

Check for MIUI updates in Settings → System Update

Reset the device

Use third-party applications (Section 3)

Try the Engineering Menu (Section 4)-->

⚠️ Note: On custom firmware devices (such as LineageOS or Pixel Experience), the Bluetooth version may not display correctly. ADB.

2. How to find out the version of Bluetooth on the Xiaomi model (database)

If your smartphone doesn’t show the Bluetooth version in the settings, you can check it by the specifications of the model. We collected data for popular Xiaomi, Redmi and POCO devices (2019-2026):

A full list of models with Bluetooth versions can be found on the official Xiaomi website in the device specifications section. Please note that sometimes the specs indicate the maximum version (for example, 5.2), but the real firmware may not support it due to driver limitations.

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

If standard methods don't work, install one of the specialized applications that reads data directly from the system and often shows more information than MIUI:

• 📊 AIDA64 — displays the Bluetooth version in the System section → Bluetooth also shows supported codecs and profiles (A2DP, HFP etc.).
• 🔧 CPU-Z — soc → Cons: Not always working correctly on new Qualcomm chips.
• 🛠️ DevCheck – Hardware section → Bluetooth, showing the version, MAC-address and list of associated devices.
• 🔍 Bluetooth Scanner – scans nearby devices and displays versions of them (useful for compatibility checks).

Important: Some applications (e.g. AIDA64) may require a paid version to unlock full data. Free versions usually show basic information.

💡

If the app shows the Bluetooth version as Unknown, try clearing its cache in Settings → Apps → [Program Name] → Memory → Clear the cache.

4. Engineering menu: a hidden way for power users

The Engineering Mode contains low-level hardware information, including Bluetooth module data, which works on most Xiaomi devices, but requires caution — don’t change settings unless you’re sure they’re there!

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636## (for testing).
3. In the menu that appears, select Phone Information.
4. Scroll down to the Bluetooth block – there will be a string with the version (e.g. Bluetooth: 5.2).

If the combination does not work, try:

• 🔢 ##284## - Bluetooth test on some models).
• 🔢 ##225##: An alternative way to get information about the module.

⚠️ Attention: On devices with MIUI 14 and newer engineering menus may be blocked. ADB (section (5) or annexes of section 3.

💡

The engineering menu is the most reliable way, but it requires caution: Do not change the settings in the RF Test or Hardware Testing sections, so as not to disrupt the module.

5. Verification through ADB (for developers and advanced users)

If none of the previous methods worked, you can get a Bluetooth version via Android Debug Bridge (ADB), which requires a connection to a computer, but gives a 100% accurate result.

Instructions:

1. Install. ADB-PC drivers.
2. Turn on USB Debugging on your smartphone: Settings → About Phone → MIUI Version (tap 7 times to unlock Developer Mode). Then go back to Settings → Additional → Developer → Debugging on USB.
3. Connect the device to the PC and execute the command in the terminal: adb shell dumpsys bluetooth_manager In the conclusion, find the mAdapterProperties string – there will be a version (for example, version).=5.2).

Alternative command for new versions of Android:

adb shell settings get global bluetooth_version

On devices with Qualcomm Snapdragon 8 Gen 2 chips (such as Xiaomi 13 Ultra), the Bluetooth version may appear as 6.0, but only 5.3 is actually supported due to driver limitations.

6.What to do if the Bluetooth version is not determined?

If neither method showed a Bluetooth version, the problem could be:

• 🔄 Outdated firmware - update MIUI Up to the latest version in Settings → Updating the system.
• 🛠️ Damaged Bluetooth module – if the device does not find other gadgets or permanently shuts down, repair may be required.
• 📱 Custom firmware – some builds (such as Havoc-OS) may not display data correctly.
• 🔒 Manufacturer restrictions on some models (e.g. Redmi) 9A) Bluetooth version is deliberately hidden.

If you are critical to know the version (for example, to connect Xiaomi Buds 4 Pro with support for LE Audio), try:

1. Reset network settings: Settings → Connections → Reset your Wi-Fi, mobile network, and Bluetooth settings.
2. Install alternative software (e.g. Pixel Experience) if the warranty expires.
3. Contact the Xiaomi service center with a request to provide technical data of the device.

7. Compatibility of Bluetooth versions with Xiaomi gadgets

Knowing the Bluetooth version will help avoid problems when connecting accessories. For example, Xiaomi Buds 4 headphones require Bluetooth 5.2+ to work LE Audio, and Mi Band 8 fitness bracelets are compatible with Bluetooth 5.0 and later. In the table below, the minimum requirements for popular gadgets are:

If your smartphone supports a newer version of Bluetooth than the gadget, the connection will work, but some features (such as dual connectivity or low latency) may not be available.
