Xiaomi smartphone owners (including the Redmi and POCO line) often face the need to know the version of the Bluetooth module – whether it is to check compatibility with wireless headphones, fitness bracelets or the car system. The protocol version depends not only on data transfer speed, but also on the stability of the connection, range, and support for modern functions like LE Audio or Dual Audio.
Unfortunately, MIUI doesn’t always show this information explicitly, unlike the Android version or the processor model. However, there are at least 5 reliable ways to identify the Bluetooth version on your device, including hidden menus, third-party apps and technical specification analysis. In this article, we’ll go through each method in detail, taking into account the features of different Xiaomi models (from the budget Redmi Note to the flagship Xiaomi 13).
1. Check through phone settings (official method)
The easiest, but not always working method is to search for information in standard MIUI settings. the manufacturer sometimes specifies the Bluetooth version in the About Phone section, but this depends on the firmware version and device model.
Follow the instructions:
- 📱 Open the Settings app (cog icon on the home screen).
- 🔍 Scroll down and select About Phone (or About Device on some versions) MIUI).
- 📋 Tap on item All characteristics (may be called Software Information or Hardware Information).
- 🔎 Look for the Bluetooth string – version may be listed here (e.g. Bluetooth 5.2).
If this section doesn’t show the version, don’t worry: most Xiaomi devices (especially budget) have this information hidden.
💡
On some MIUI firmware, the Bluetooth version only appears when connected to another device. Try turning on Bluetooth and tucking the phone with headphones or a speaker, then check the About section again.
2.Use of the engineering menu (for experienced users)
The hidden engineering menu (or Engineer Mode) provides detailed information about the hardware of the smartphone, including data about the Bluetooth module, which is suitable for advanced users, as it requires the input of special codes.
Instructions:
- Open the Phone app and type in the combination: ##4636## Some Xiaomi models may have code triggered: ##225###
- If the code worked, you’ll see the Testing menu or Phone Information.
- Go to the Bluetooth tab (can be called BT Info or RF Information).
- The Bluetooth Version or BT Chip block will specify the protocol version (e.g., 5.0, 5.2).
⚠️ Note: Not all codes work on new Xiaomi models (e.g. Xiaomi 14 or Redmi Note 13) If nothing happens after code entry, the engineering menu is blocked by the manufacturer.

3. Third-party diagnostic applications
If standard methods don't work, specialized utilities will come to the rescue, analyzing the hardware of the smartphone and output detailed data, including the Bluetooth version.
Top.-3 tested applications:
- 📊 AIDA64 — Shows the Bluetooth version in the System section → Bluetooth: The free version contains ads, but the functionality is unlimited.
- 🔧 CPU-Z — The SoC tab (system on chip) sometimes contains information about the Bluetooth module, especially on devices with Qualcomm chips.
- 🛠️ DevCheck – in the Hardware section, displays the Bluetooth version and supported code (e.g., aptX, LDAC).
An example of the mapping in AIDA64:
| Parameter | Meaning (example) |
|---|---|
| Bluetooth Version | 5.2 |
| Bluetooth Chip | Qualcomm WCN6750 |
| Supported Profiles | A2DP, AVRCP, HFP, HSP |
| LE Features | LE Audio, Dual Mode |
🔹 Important: Some applications may show a version of the protocol supported by the chipset (e.g., Snapdragon 8 Gen 2 supports Bluetooth 5.3), but the actual version of the module in the phone may be lower.

4. Checking the model of the phone on the official website
If you don’t have access to your phone (for example, you’re just planning to buy), or previous methods didn’t work, use Xiaomi’s official technical specifications.
How to find information:
- Go to mi.com (global version) or xiaomi.ru (for Russia).
- In the search box, type in the exact model of your phone (e.g. Redmi Note 12 Pro+ 5G).
- On the device page, look for the Specifications tab (or Technical Details).
- The Wireless Networks or Connectivity section will include the Bluetooth version.
Example for Xiaomi 13 Pro:
Wireless networks: Wi-Fi 6E, Bluetooth 5.3, NFC, infrared port.
⚠️ Note: Some regional versions of the site (e.g. India or China) may have different data. Always check the specifications for your specific market, as Xiaomi sometimes releases modifications with different iron.

5. Analysis of the chipset and technical documentation
The Bluetooth version depends on the chipset installed in the phone, and knowing the SoC model, you can determine the maximum possible version of the protocol, even if the phone has not yet been released or the data is hidden in MIUI.
Comparison of popular Xiaomi chipsets and Bluetooth versions:
| Chipset | Xiaomi models | Bluetooth | Features |
|---|---|---|---|
| Snapdragon 8 Gen 2 | Xiaomi 13, 13 Pro, Redmi K60 Pro | 5.3 | LE Audio support, improved energy efficiency |
| Snapdragon 7+ Gen 2 | Redmi Note 12 Turbo, POCO F5 | 5.3 | Dual Bluetooth (Simultaneous Connection to 2 Devices) |
| Dimensity 9000+ | Xiaomi 12T Pro | 5.3 | Low latency in audio transmission |
| Snapdragon 695 | Redmi Note 11 Pro+, POCO X4 Pro | 5.2 | Support for aptX Adaptive |
| Helio G99 | Redmi 12, POCO M6 Pro | 5.2 | Limited support for Dual Audio |
🔹 How to find out your phone’s chipset?
- In the AIDA64 app, go to the CPU (or SoC) section.
- In MIUI settings: Settings → About phone → All characteristics → Processor model.
- On the device box (usually indicated in the specifications).
Important: The Bluetooth version in the chipset doesn't always match the actual version in the phone.The manufacturer can use the older module to save costs (e.g., the Snapdragon 888 supports Bluetooth 5.2, but the Redmi K40 has a 5.1 module installed).
6. Check through ADB (for advanced users)
If you're familiar with ADB, you can get Bluetooth data directly from your system logs, and this method requires a computer and USB debugging enabled, but it gives you the most accurate information.
Step-by-step:
- Turn on Developer Mode on your phone: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → Developer. Activate USB Debugging.
Connect your phone to your computer via USB (use the original cable).
adb shell dumpsys bluetooth_managermBluetoothVersion = 5.2
mControllerVersion = 95.2 is the protocol version and 9 is the internal controller code.
⚠️ Attention: Use ADB Do not change system parameters through this utility if you are not sure of your actions - this can lead to malfunctions in Bluetooth or even complete inoperability of the module.
💡
ADB-This method is suitable for diagnosing Bluetooth problems (e.g., if the device is not detected or often disconnected.
