How to find out which Bluetooth is installed on Xiaomi phone: all the ways

Xiaomi smartphone owners (including Redmi and POCO sub-brands) often face the need to know the Bluetooth version of their device, which may be used to verify compatibility with wireless headphones, speakers, fitness bracelets or car systems, but the manufacturer does not always explicitly specify this technical specification — it has to be searched in hidden menus, documentation or third-party sources.

A specific version of Bluetooth (e.g., 4.2, 5.0 or 5.3) not only determines data transfer speeds, but also power consumption, communication range and support for modern profiles (e.g., LE Audio or LC3). In this article, we will analyze all the current methods - from standard MIUI settings to engineering menus and online services.

If you plan to connect Bluetooth 5.2+ devices to your phone (such as Xiaomi Buds 4 Pro headphones or Redmi SoundBar speakers), it’s important to make sure that your smartphone doesn’t become a bottleneck in the chain.

1. Verification through MIUI settings (the easiest way)

On most Xiaomi smartphones, the Bluetooth version can be recognized through the standard settings menu, but the path to this information depends on the version of MIUI. In recent updates (starting with MIUI 12), the algorithm has been simplified, but on older firmware (MIUI 10-11) additional actions may be required.

Instructions for MIUI 12/13/14:

1. Open the Settings app (cog icon).
2. Go to the About Phone (or About Device) section.
3. Slip on the item All characteristics (or characteristics of the device).
4. Scroll down to the Network and Communication block – there will be a Bluetooth string indicating the version (e.g. Bluetooth 5.2).

⚠️ Note: Some models (e.g. Redmi Note 10 Pro) POCO X3 The Pro version may not be displayed correctly, so instead of 5.0, you'll see 4.2, but it actually supports a more modern standard. MIUI, Alternative methods should be used (see the following sections).

Check for MIUI updates in Settings → System Update

Reboot the phone.

2. Engineering menu (for experienced users)

If standard settings don’t show a Bluetooth version, you can turn to a hidden engineering menu (also known as MTK Engineer Mode or Qualcomm Service Menu) that works on most Xiaomi devices, but requires caution – wrong actions can disrupt the communication module.

Instructions for Qualcomm processors (most flagships and mid-budget models):

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 – there will be a Bluetooth version string with an exact value (e.g. 5.2 [LE]).

For devices on Mediatek (e.g. Redmi 9A or POCO C31):

1. Enter the dialer: ##36446337##
2. Go to Hardware Testing → Connectivity → Bluetooth.
3. At the top of the screen will be the version of the protocol.

⚠️ Warning: Do not change any settings in the engineering menu unless you are sure of their purpose! HCI Snooping can lead to problems with the connection of headphones.

3. Third-party diagnostic applications

If previous methods didn’t work, Google Play will provide you with specialised tools that will not only show you the Bluetooth version, but also provide additional information about the module: supported code (such as aptX or LDAC), maximum data rate, and even the current connection status.

Top.-3 tested applications:

• 📱 AIDA64 — It shows full specifications, including the Bluetooth version and supported profiles, and the free version limits some features, but it's enough for our task.
• 🔍 CPU-Z — The SoC tab contains a Bluetooth partition with detailed information about the chip (e.g., Broadcom). BCM4356 Bluetooth 5.1).
• 🛠️ DevCheck is a minimalist interface with a focus on hardware components.The Bluetooth version is displayed in the Hardware block.

How to use AIDA64:

1. Install the app from Google Play.
2. Open the Device section → Bluetooth.
3. The Bluetooth version bar will specify the exact standard (e.g., 5.2 (LE, EDR)).
4. Note the line Bluetooth address – this is MAC-The address of your module that you may need to diagnose connection problems.

⚠️ Note: Some applications (e.g. Bluetooth Scanner) require location permission to scan devices.This is due to Android 12 restrictions+, But it doesn't mean that the app collects your data. If you don't allow it, you won't be able to scan the nearest device, but the version of your module will still show up.

4. Official specifications on Xiaomi website

If you can't identify the Bluetooth version with software, you can always go to official sources. The manufacturer publishes the full specifications for each model on its website, but there are nuances:

• 🌍 The module version may vary depending on the regional firmware (e.g. global firmware). MIUI Global vs. Chinese MIUI China).
• 🔄 On some models (e.g. Xiaomi) 11T Pro) Bluetooth module updated in new device revisions without changing model name.
• ⚡ In budget smartphones (for example, Redmi). A1) Bluetooth 5.0 can be specified, but only basic functions are supported without the actual LE Audio.

How to find the specifications:

1. Go to the official Xiaomi or Redmi website.
2. In the search box, type in the full name of your model (e.g. Xiaomi 12 Pro 5G).
3. On the device page, open the Specifications tab (or Characteristics for the Russian version of the site).
4. Find the Wireless Networks section or Wireless Networks section, and the Bluetooth version will be listed there.

Important: The site may list the best possible version of Bluetooth for this model, but the actual version depends on the firmware installed. For example, POCO F3 officially supports Bluetooth 5.1, but on older versions MIUI can work as 5.0.

5. Check through ADB (for advanced users)

If you're familiar with the developer tools, you can find out the Bluetooth version through ADB (Android Debug Bridge), which is the most accurate method, because it reads data directly from the system.

Instructions:

1. Turn on Developer Mode on your phone: go to Settings → About Phone and tap the MIUI version 7 times.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your phone to your PC and open the command line (or Terminal on Mac/Linux).
4. Enter the command: adb shell dumpsy bluetooth_manager In the conclusion, find the line mAdapterProperties - there will be the version.

Alternative command for obtaining advanced information:

adb shell settings get global bluetooth_version

⚠️ Attention: Use ADB requires installed drivers and enabled debugging on USB. Untrained users are not advised to change other settings through ADB, This can cause system failures.

💡

If the adb shell dumpsy command bluetooth_manager If you get the error back, try to type adb root first. MIUI Access to system data is limited.

6.How the Bluetooth version affects the performance of Xiaomi devices

Knowing the Bluetooth version will help you avoid problems when connecting accessories.

• 🎧 Xiaomi Buds 4 Pro headphones require Bluetooth 5.2+ work LE Audio and Spatial Sound.
• 🚗 Automotive systems (such as Android Auto) may not support older versions of the protocol (4.0 and below).
• 🎮 Xiaomi Game Controller is optimized for Bluetooth 5.0 and higher – 4.2 will be a noticeable input delay.

Common problems and their causes:

Critical nuance: On devices with Bluetooth 4.2 and below, it is impossible to use the Dual Audio function (simultaneous connection of two headphones), even if it is stated in the MIUI specifications.

💡

If your Xiaomi smartphone is released before 2019, it most likely has a Bluetooth 4.2 or 5.0 module without support for modern features like LE Audio.
