Why it’s important to know the Bluetooth version of your Xiaomi
Owners of Xiaomi, Redmi and POCO smartphones often face the need to know the version of their device’s Bluetooth module, which is critical when connecting modern gadgets – from wireless AirDots headphones to Mi Band smartwatches. For example, Bluetooth 5.0 supports twice the data transfer speed compared to 4.2, and Bluetooth 5.2 adds the LE Audio feature for multithreaded sound.
The manufacturer doesn’t always specify the version of the module in the basic characteristics of the phone, especially in budget models. Meanwhile, it depends on compatibility with accessories, connection stability and even power consumption. For example, if your Xiaomi 12T does not see the Sony WH-1000XM5 headphones, the problem may lie in the outdated version of the protocol.
Method 1: Through standard Android settings
The easiest method is to use the built-in MIUI tools, but it doesn’t work on all devices, as Xiaomi sometimes hides technical details in the user interface.
- Open the Settings app (the gear icon on the home screen).
- Go to the About Phone section (usually at the bottom of the list).
- Slip on the item All characteristics or characteristics of the device.
- Scroll down to the Network or Wireless Networks block.
If you have a Bluetooth version, you're lucky. Otherwise, try the alternative path: Settings → Connections and Sharing → Bluetooth. Some firmware shows the version at the top of the screen next to the switch.
💡
On smartphones with MIUI 14 and later, the Bluetooth version can be hidden behind the “Additional” button (three dots in the upper right corner of the Bluetooth menu).
⚠️ Note: On custom firmware devices (e.g. LineageOS), standard settings may display an incorrect version.
Method 2: Through AIDA64
AIDA64 is a Swiss knife for smartphone diagnostics, and it provides detailed hardware information, including a Bluetooth chip version, free of charge, download it from Google Play and follow the instructions:
Install the app AIDA64|Open the "System" section"|Select "Devices"|Find the line "Bluetooth" and see the version of the protocol-->
In the Devices section, you’ll see a Bluetooth bar showing the chip model (like Qualcomm WCN3990) and protocol version (5.2). If the version doesn’t show, try updating the application database in AIDA64 settings.
The advantage of this method is to work on any device, including older models like the Redmi 4X or Mi A1. However, note that some Chinese firmware blocks access to low-level information, in which case only the engineering menu (mode 4) will help.
| Xiaomi model | Typical Bluetooth chip | Version of protocol |
|---|---|---|
| Xiaomi 13 Pro | Qualcomm WCN6750 | 5.3 |
| POCO F5 | Qualcomm WCN6855 | 5.3 |
| Redmi Note 12 | Qualcomm WCN6750 | 5.2 |
| Mi 11 Lite | Qualcomm WCN3990 | 5.1 |
Method 3: Checking the phone model on the official website
If the software methods didn't work, consult the technical specifications of the device. On the official Xiaomi website or resources like GSMArena, all the specifications are listed, including the Bluetooth version.
- Go to the official Xiaomi website.
- Type your phone model into the search bar (e.g. Redmi Note 11 Pro+ 5G).
- Open the Specifications tab.
- Find the Wireless Network or Connectivity section.
Note that the manufacturer may specify the most supported version of the protocol, rather than the one that actually works on your device.For example, Xiaomi Mi 10T officially supports Bluetooth 5.1, but in practice, some users face restrictions due to regional firmware.

⚠️ Note: On reseller sites (such as AliExpress or Amazon), the characteristics may be incorrectly specified.
Method 4: Engineering menu (for advanced users)
This method is suitable for power users because it requires engineering code input, and works on most Xiaomi devices, but some models (such as the MediaTek processor) may require additional applications like the MTK Engineering Mode.
Instructions for devices on Qualcomm Snapdragon:
- Open the Phone app.
- Enter the code ##4636## (the test menu will open).
- Select the item Phone Information.
- Scroll down to the Bluetooth block - there will be a version.
For MediaTek devices, use the code ##36446337##, then go to Connectivity → Bluetooth. Be careful: improper actions in the engineering menu can cause the module to malfunction!
What to do if the engineering menu does not open?
Method 5: Through ADB-teams (for developers)
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 preparation:
- Activate Developer Mode (7 times tap the build number in Settings → About phone).
- Enable USB debugging in the developer settings.
- Connect your phone to your PC and execute the command: adb shell dumpsys bluetooth_manager
- In the conclusion, find the Bluetooth version string.
Alternative command for obtaining advanced information:
adb shell settings get global bluetooth_versionThis method is especially useful for devices with custom firmware or custom ROM, where standard methods do not work. For example, on Xiaomi Mi A3 with Pixel Experience firmware, the Bluetooth version can only be determined through ADB.
💡
ADB-The method is the only way to get an accurate version of Bluetooth on devices with modified software or blocked engineering menus.
Frequent problems and their solutions
When checking the Bluetooth version, Xiaomi users encounter common errors, and here are the most common ones and how to fix them:
- 🔍 Version not displayed in settings: Update MIUI before the latest version or use it AIDA64.
- 📱 Engineering menu not open: Check the firmware region (Chinese versions often block codes).
- 🔌 ADB Does not recognize the device: Install Xiaomi drivers USB Drivers and turn on debugging by USB.
- 📊 The site contains conflicting data: Check the information with GSMArena or documentation Qualcomm/MediaTek.
Pay particular attention to devices with MediaTek processors (such as Redmi 10C or POCO M4 Pro), on which the Bluetooth version is often incorrectly defined due to the specific implementation of the chipset, in which case the only reliable way is to ADB or contact Xiaomi support.
If none of the methods worked, try resetting your network settings: Settings → Connections & Sharing → Reset your Wi-Fi, mobile network, and Bluetooth settings. After you restart, repeat the check.
