How to check the version of Bluetooth on a Xiaomi smartphone: all the ways

Have you bought a new wireless headphone or fitness bracelet, but aren't sure if your Xiaomi supports it? Or want to know why the connection to the car radio is unstable? The Bluetooth version is a key parameter that determines data speed, communication range and compatibility with other gadgets. In this article, we will break down all the current ways to find out what Bluetooth is on your Xiaomi, Redmi or POCO phone - from standard settings to hidden engineering menus.

The manufacturer doesn’t always specify the version of the module in the specifications of the device, especially when it comes to budget models. For example, in the Redmi Note 12 it can be Bluetooth 5.2, and in the POCO X5 Pro it is already 5.3, although it is not visible on the outside, we will show how to get accurate information without installing third-party applications, and also explain why some methods can give incorrect results on older MIUI firmware.

1. Check through phone settings (the easiest way)

On most Xiaomi smartphones, you can find out the Bluetooth version right in the settings menu — but only if the manufacturer hasn’t hidden this information. This method works on MIUI 12 and later, including the latest versions of HyperOS.

1. Open the Settings app (cog icon).
2. Go to About Phone (or About Device on some models).
3. Slip on the item All characteristics (may be called the Full Specification).
4. Scroll down to the Wireless Networks block – there will be a Bluetooth string indicating the version.

If this menu doesn’t show the version, don’t worry: on some devices (e.g. Redmi 9A or POCO M3), the manufacturer has removed this information.

💡

On some MIUI firmware, the Bluetooth version only appears after you first connect to another device. Try turning on Bluetooth and sync with your headphones or speaker, then check the settings again.

2.Use of the engineering menu (for advanced users)

The hidden engineering menu (Engineer Mode) provides detailed information about the hardware of the smartphone, including data about the Bluetooth module. This method is suitable for all Xiaomi models, but requires caution – do not change other options on the menu so as not to disrupt the phone.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636## (for some models, ##232338## may work).
3. In the menu that appears, select Phone Information (or Phone Information).
4. Scroll down to the Bluetooth section – there will be a Bluetooth address bar and Bluetooth version.

If the combination does not work, try an alternative method:

1. Install the MTK Engineering Mode app (for Mediatek chips only).
2. Run it and go to Hardware Testing → Bluetooth.
3. At the top of the screen will be the version of the protocol.

3. Verification through analysis applications

If standard methods don’t work, third-party utilities will come to the rescue, not only showing the Bluetooth version, but also providing additional information about the module: supported code (such as aptX or LDAC), maximum data rate, and even the current state of the connection.

The best applications for this task:

• 📱 AIDA64 — The full hardware specification, including the Bluetooth version and the chip maker (e.g. Broadcom or Qualcomm).
• 🔍 DevCheck is a user-friendly interface with the Hardware section, which displays the protocol version and supported profiles (for example, A2DP audio transmission).
• 🎧 Bluetooth Auto Connect – specializes in the diagnosis of wireless connections and shows the version of the module in the Device Info section.

An example of the mapping in AIDA64:

Bluetooth:




Version: 5.2




Supported Profiles: A2DP, AVRCP, HFP, HSP, OPP, PBAP




Chipset: Qualcomm WCN3998

4. Definition by phone model (Xiaomi database)

If your Xiaomi isn't turning on or you're just planning to buy, you can find out the Bluetooth version from the device model. The manufacturer publishes official specifications on its website, but sometimes the data is outdated or incomplete.

Important: On some models (e.g. Redmi 9T or POCO M4 Pro), the Bluetooth version may differ depending on the region of sale. For example, the global version (Global) often gets a newer chip than the Chinese one (China).

Check your model’s exact name in the settings along the way: Settings → About Phone → Model. If the name has suffixes like 5G, Pro or Lite, look for specifications for this particular modification.

5. Verification through ADB (technical)

If you're familiar with the developer tools, you can find out the Bluetooth version through ADB (Android Debug Bridge), which is 100% accurate, but requires connecting the phone to a computer and installing Google's Platform Tools.

Instructions:

1. Turn on USB Debugging on your phone (Settings → About Phone → MIUI version – tap 7 times, then return to Additional → For Developers).
2. Connect your phone to your PC and open the command line in the adb folder.
3. Enter the command: adb shell dumpsy bluetooth_manager
4. In the output, look for the Bluetooth version bar or mController.getRemoteVersion.

Example of conclusion:

BluetoothManager:




mAdapterProperties:




name=Redmi Note 11




address=XX:XX:XX:XX:XX:XX


    version=5.2


...

Install USB drivers for Xiaomi

Download Platform Tools from Google

Enable debugging over USB on your phone

Connect your phone with the original cable (not charging!)

Check that the phone is determined in the command line (adb devices command)-->

This method is especially useful if you suspect that the manufacturer has hidden the real version of Bluetooth in the firmware. For example, some Redmis with a Mediatek Helio G88 chipset may display Bluetooth 5.0 in the settings, when in fact the module supports 5.1.

6.How do you know which version of Bluetooth you need?

Knowing the version is only half the battle, and it's important to understand what it's going to offer and whether it's compatible with your gadgets, and here are the key differences between the versions:

• 🔄 Bluetooth 4.0-4.2: Basic support BLE (Low Energy, speeds up to 1 Mbps Suitable for fitness bracelets and simple headphones, but can slow down when transmitting music.
• 🎵 Bluetooth 5.0: Double speed (2 Mbps), increased range (up to 40 m in ideal conditions) and Dual Audio support (connecting two headphones at the same time).
• 🔊 Bluetooth 5.1-5.2: Improved connection stability, support LC3 (Best sound quality with low bitrate, function LE Audio for hearing aids.
• 🚀 Bluetooth 5.3: Even less power consumption, fast reconnection to devices, improved synchronization for games (low latency).

If your Xiaomi supports Bluetooth 5.0+, but the headphones or speaker are unstable, the problem may be:

• 🔋 Discharged battery gadget (Bluetooth begins to "brake" at low charge).
• 📶 Interference from other wireless devices (Wi-Fi router, microwaves).
• 🔄 Outdated headphone firmware (check updates in companion app).

💡

Bluetooth 5.0 and later backwards compatible with older versions (4.2, 4.0), but speed and range will be limited by the capabilities of the weakest device in the pair.

For gamers and music lovers, support for codes is critical:

• aptX Adaptive – Low latency (ideal for gaming)
• LDAC is a high quality sound (up to 990 kbps), but consumes more battery.
• AAC is a balanced option for iPhone and Android.

You can find out what code your Xiaomi supports in the Developer Options app (includes through 7 taps on the MIUI version) in the Bluetooth Audio Codec section.

💡

If your phone supports Bluetooth 5.0+, but the headphones only connect in 4.2 mode, try resetting them (press the power button for 10 seconds) and reconnecting them.

Frequent Questions (FAQ)

💡

If your Xiaomi supports Bluetooth 5.0+, but the headphones are jammed, try manually selecting the codec in the developer settings (Settings → For developers → Bluetooth Audio Codec).

Now you know all the ways to find out the Bluetooth version of your Xiaomi phone, and you can determine exactly if your smartphone is compatible with new gadgets. If none of the methods worked, write a model of your device in the comments, and we will help you find a solution!
