How to watch the Bluetooth version on the Xiaomi Redmi smartphone: all available methods

You’re trying to connect your Xiaomi Redmi wireless headphones, fitness bracelets or other device, but you’re facing compatibility issues? Perhaps it’s the Bluetooth version – older smartphone models (like the Redmi 4X or Redmi Note 5) only support Bluetooth 4.2, while modern gadgets require 5.0 and higher. In this article, we’ll look at all the possible ways to learn the Bluetooth version on your Xiaomi – from standard settings to hidden engineering menus.

It is important to understand that the Bluetooth version is not only dependent on the smartphone model, but also on the version of the MIUI firmware. For example, after upgrading to MIUI 14, the Redmi Note 10 Pro may support new Bluetooth profiles, even if the hardware remains the same. We will also explain how to check the hardware and software versions of the module – this will help diagnose connection problems.

If you are not sure about your Redmi model, check it first with the settings: Settings → About Phone → Device Model. This information will be useful for comparison with our compatibility table at the end of the article.

1. Verify the Bluetooth version through the standard Android settings

The easiest way is to use the built-in MIUI tools. Unfortunately, in the latest versions of the shell (starting with MIUI 12), developers have removed the direct display of the Bluetooth version from the interface, but it can be found indirectly.

Follow the instructions:

1. Open the settings on your Xiaomi Redmi.
2. Go to About Phone (sometimes called About Device).
3. Tap a few times on the MIUI version until you get a message You are a developer! (this will unlock Developer Options).
4. Return to the main Settings menu and select a new section Additional → Developer options.
5. Scroll down to the Network block and find the Bluetooth version.

If you don't have Bluetooth, don't worry. That means your firmware doesn't show that information explicitly, so move on to the following methods.

💡

If the Developer Settings section has already been activated, but there is no Bluetooth option, try resetting the developer settings: → Annexes → Application management → Settings → Warehouse → Clear the data. Then re-activate the developer mode.

2.Use of the Engineering Menu (MTK and Qualcomm)

Xiaomi Redmi smartphones with MediaTek processors (Helio G85, Helio G95, etc.) or Qualcomm Snapdragon (Snapdragon 660, Snapdragon 732G) can get detailed information about the Bluetooth module through the engineering menu. This method requires caution, since wrong actions can disrupt the network.

Instructions for MediaTek:

1. Open the Phone app.
2. Enter the combination: ##4636### (or #36446337## for new models).
3. Select Phone Information (or Hardware Testing).
4. Scroll to the Bluetooth block – the module version (e.g. BT 5.0) will be listed here.

For Qualcomm Snapdragon:

1. Enter the phone app: ##2254##.
2. In the menu that opens, find the Bluetooth Device Address section – a version may be displayed next to it.

⚠️ Warning: Do not change the settings in the engineering menu unless you understand their purpose! For example, resetting the Bluetooth module settings (BT Reset may result in the loss of all associated devices.

3. Diagnostic applications: AIDA64 and CPU-Z

If standard methods don’t work, third-party utilities will come to the rescue, the two most reliable Bluetooth validation apps are AIDA64 and CPU-Z. They don’t require root rights and provide detailed information about the hardware of the smartphone.

Instructions for AIDA64:

1. Download AIDA64 from Google Play.
2. Open the application and go to the System section.
3. Select Bluetooth – here will be the version of the module, MAC-Address and supported profiles (e.g, A2DP, AVRCP).

Instructions for CPU-Z:

1. Install CPU-Z from Google Play.
2. Go to the SoC tab (system on a chip).
3. Scroll down to the Bluetooth block and a version (e.g. v5.1) will be displayed here.

Both apps also show the Bluetooth chip maker (like Broadcom, Qualcomm or MediaTek), which is useful for diagnosing compatibility issues.

🔹 Bluetooth version (for example, 4.2 or 5.0)

🔹 MAC-Module address (must match the address in Android settings)

🔹 Supported profiles (A2DP, HFP, HSP etc.)

🔹 Chip manufacturer (Qualcomm, Broadcom, etc.)

🔹 Chip temperature (if too high, overheating is possible)-->

4. Verification through ADB (for power users)

If you're familiar with Android Debug Bridge (ADB), you can get a Bluetooth version via the command line.This method is suitable for all Xiaomi Redmi models, but requires a connection to a computer.

Instructions:

1. Enable USB Debugging in Developer Settings.
2. Connect your smartphone to your PC and open the terminal (or Command Prompt in Windows).
3. Enter the command: adb shell dumpsy bluetooth_manager
4. In the output, find the mAdapterService string - next to the version will be indicated (for example, BluetoothAdapter: BluetoothDevice(00:11:22:33:44:55) name=null alias=null version=5.0).

Alternative command for obtaining advanced information:

adb shell settings get global bluetooth_version

However, it does not work on all MIUI firmware.

⚠️ Attention: Use ADB This can cause failures if you type commands at random, such as the adb shell pm disable-user command. --user 0 com.android.bluetooth will disable the Bluetooth module completely, and it will have to be restored through resetting.

5. Determination of the version according to the Xiaomi Redmi model

If none of the methods worked, you can find out the Bluetooth version from your smartphone model. Below is a table with popular Xiaomi Redmi devices and their specifications. Please note that in some regions (for example, for the Redmi Note 8 Pro in India), other versions of the module may be used.

If your model is not in the table, check its specifications on the official Xiaomi website or in the GSMArena database. For example, for the Redmi Note 11 Pro+ 5G, Bluetooth 5.2 with support for LE Audio is used.

4.2. or lower

5.0

5.1

5.2 or higher

Frequent problems and their solutions

Sometimes users find that the Bluetooth version in the settings does not match the actual hardware version. Let's look at typical situations and how to fix them.

Problem 1: AIDA64 displays Bluetooth 5.0, but the headphones only work in 4.2 mode.

• 🔹 Reason: Firmware MIUI This can limit the functionality of the module, for example, on the Redmi Note 9 Pro with MIUI 11 Bluetooth 5.0 is not working properly.
• 🔹 Solution: Update your firmware to the latest version or install custom firmware (e.g. Pixel Experience).

Problem 2: After the MIUI update, devices stopped connecting.

• 🔹 Reason: Reset Bluetooth module settings or conflict with new profiles (e.g, LE Audio in Bluetooth 5.2).
• 🔹 Solution: Remove all associated devices in Settings → Bluetooth, then reboot your smartphone and connect them again.

Problem 3: The Bluetooth version does not appear on the engineering menu.

• 🔹 Reason: On some firmware (for example, MIUI Global for Redmi K40) Access to information is limited.
• 🔹 Solution: Use Google Play's DevCheck app - it often shows data where standard methods don't work.

💡

If the Bluetooth version is still undetected after all the manipulations, it is likely that the problem is in the hardware (a module or antenna is damaged), in which case, contact the Xiaomi service center for diagnosis.
