How to watch the Bluetooth version on a Xiaomi smartphone: all working methods

Owners of Xiaomi, Redmi or POCO smartphones often face the need to know the version of the Bluetooth module - whether it is to check compatibility with headphones, a fitness bracelet or a car radio. However, standard MIUI settings do not always display this information explicitly. Depending on the device model (for example, Xiaomi 13 Pro vs Redmi Note 10) and the firmware version, the methods of verification may vary.

In this article, we’ll discuss 5 reliable methods to determine the Bluetooth version on Xiaomi, from simple (through the settings menu) to advanced (using ADB or third-party utilities), and how to decrypt version designations (such as 5.2 LE or 4.2 EDR) and why a new version doesn’t always mean better compatibility with accessories. If your smartphone doesn’t display the version in the settings, no problem: we’ll provide alternative solutions.

Why it is important to know the version of Bluetooth in Xiaomi

The Bluetooth version directly affects:

• 🎧 Sound quality – starting with Bluetooth 5.0, aptX codecs are supported HD and LDAC, which provide a sound close to CD-quality.
• 🔋 Energy consumption – Bluetooth 4.2 and later are optimized for wearable devices (e.g. Mi Band), which extends battery life.
• 📶 Communication range - Bluetooth 5.x Increases the range to 240 meters (in theory) against 10-30 meters for Bluetooth 4.0.
• 🔄 Data transfer speed – for example, Bluetooth 5.2 allows you to transfer files at speeds up to 2 Mbps (versus 1 Mbps for 4.0).

In addition, some devices (such as Sony WH-1000XM5 wireless headphones or Apple AirTag gadgets) require a specific version of Bluetooth to work properly. If your Xiaomi does not support Bluetooth 5.0+, you may experience connection problems or limited functionality.

Method 1: Checking through MIUI settings (the easiest method)

On most Xiaomi smartphones, you can find out the Bluetooth version through the standard settings menu, but the path to this information depends on the version of MIUI:

1. Open the Settings app (cog icon).
2. Go to About Phone (or Device on new MIUI versions).
3. Put on the item All characteristics (or information about the software).
4. Scroll down to the Networking Technology block – there should be a Bluetooth string indicating the version (e.g. Bluetooth 5.2).

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

1. Open Settings → Connections and Sharing → Bluetooth.
2. In the upper right corner, press three dots (⋮) and select the Advanced Settings.
3. In some firmware, the version appears at the bottom of the screen under the label Bluetooth version.

⚠️ Note: On some Xiaomi models (e.g, POCO X3 Pro or Redmi 9A) The Bluetooth version can be hidden in the firmware. In this case, go to Method 2.

Method 2: Use the AIDA64 application (for all models)

If standard settings don’t show the Bluetooth version, use the free AIDA64 app (similar to CPU-Z for Android) that displays all the device’s specifications in detail, including Bluetooth module data.

Instructions:

1. Download AIDA64 from Google Play.
2. Launch the application and provide access to device information.
3. Go to the Device section → Bluetooth.
4. In the Bluetooth Information block, find the lines: Bluetooth Version (e.g. 5.2) MAC Address (unique module identifier) Supported profiles (e.g. A2DP, HFP)

AIDA64 also shows the manufacturer of a Bluetooth chip (e.g. Qualcomm or Broadcom), which is useful for diagnosing compatibility issues. If the application displays Unknown instead of the version, this may mean that the firmware does not recognize the module (solved by the MIUI update).

Method 3: View through the Engineering Menu (for power users)

On some Xiaomi smartphones, you can find out the Bluetooth version through the engineering menu (or MTK Engineer Mode for MediaTek devices), a method that requires caution, as incorrect actions can disrupt the module.

Instructions for Qualcomm devices (for example, Xiaomi 12T, Redmi K50):

1. Open the Phone app.
2. Enter the combination: ##4636## (Testing menu opens).
3. Select the item Device Information.
4. Scroll down to the Bluetooth block - the version will be listed here.

For devices on MediaTek (e.g. Redmi Note 11, POCO M4 Pro):

1. Install the MTK Engineer Mode app.
2. Open it and go to Hardware Testing → Bluetooth.
3. The Bluetooth Version field will show the module version.

⚠️ Warning: Don't change the settings in the engineering menu unless you're sure they're there! This can cause Bluetooth or Wi-Fi to crash.

Method 4: Checking through ADB (for advanced users)

If none of the previous methods worked, you can use ADB (Android Debug Bridge), a tool for debugging Android devices, which is suitable for all Xiaomi models, but requires a connection to a computer.

Instructions:

1. Turn on Developer Mode on your smartphone: Go to Settings → About Phone. Tap 7 times on MIUI Version (you will be notified you are a developer!). Go back to Settings → Additional → For Developers and enable USB Debugging.

Connect your smartphone to your computer through USB-cable (use the original cable for a stable connection).

ADB Tools

cmd

Terminal

adb shell dumpsys bluetooth_manager

BluetoothAdapter

LE 5.2

Alternative command for more detailed information:

adb shell settings get global bluetooth_version

If the command returns the empty value, try:

adb shell getprop ro.bluetooth.version

💡

If ADB doesn’t recognize the device, check the USB drivers for Xiaomi at MIUI Downloads. Also try using a USB 2.0 port instead of USB 3.0 – this often solves connection problems.

Method 5: Search the smartphone model (if other methods don’t work)

If none of these methods worked, you can find out the Bluetooth version from your Xiaomi model.

1. Find out the exact device model: Go to Settings → About Phone → Device Model (e.g. 2201116PG for Redmi Note 11 Pro+ 5G). Or look at the smartphone box.
2. Find the model specifications on official resources: Xiaomi Global website (Support → Specifications section), GSMArena database (enter model in search), device page on Xiaomi Firmware Updater.

Example for popular models:

⚠️ Note: The Bluetooth version may vary depending on the regional firmware. 12T Europe (EEA) It can have Bluetooth 5.2 and for China (CN) — 5.3.Clarify the data for your version MIUI.

What to do if the Bluetooth version is outdated

If your Xiaomi is equipped with Bluetooth 4.0-4.2, you may face limitations:

• 🚫 Unable to connect to Bluetooth 5.0 devices+ (For example, AirPods Pro 2 or Sony WH-1000XM5).
• 🎵 Degraded sound quality when listening to music AAC or SBC.
• 🔋 Faster battery drain when using wireless headphones.
• 📶 Unstable connection at a distance of more than 10 meters.

Decisions:

1. Update MIUI – sometimes new firmware versions will activate the hidden capabilities of the Bluetooth module.
2. Use an external Bluetooth adapter (such as USB-C Bluetooth 5.0 Dongle) if your smartphone supports OTG.
3. Buy compatible accessories – for example, headphones with Bluetooth 4.2 support (for example, Redmi Buds 3 Lite).
4. Consider upgrading your smartphone if Bluetooth is critical for your tasks (like working with a smart home or gaming controllers).

💡

The Bluetooth version is hardware-defined, it can't be changed software-wise, and the only way to get a new version is to upgrade your smartphone or use an external adapter.
