Owners of Xiaomi, Redmi and POCO smartphones often face the need to clarify the specifications of their device, especially when it comes to wireless connections. The Bluetooth version is a critical parameter that determines data speed, range and compatibility with modern accessories such as headphones, smartwatches or car systems. If you are planning to buy a new gadget or troubleshooting communication problems, knowing the exact specification of the communication protocol will be a key factor.
Unfortunately, the MIUI or HyperOS shell interface doesn’t always provide this information explicitly on the home settings screen. Manufacturers often hide detailed data about the iron platform, leaving the user in the dark about codec support or the relevance of the standard. In this article, we’ll look at all the available methods, from simple paths through menus to advanced methods using engineering codes and computer utilities.
Understanding the difference between the specification version and the actual performance of the module will help to avoid disappointments. For example, the Xiaomi Redmi Note 10 can support one standard, while the older Redmi Note 8 is already outdated.
⚠️ Attention: Use of engineering menus and debugging commands requires caution. Changing unknown parameters in system partitions can lead to unstable operation of communication modules.
Why you need to know the Bluetooth version on your smartphone
Many users ignore this option until they encounter connectivity issues. The data protocol evolves, and each new version brings significant improvements. For example, the transition from 4.2 to 5.0 quadrupled the range, and newer versions like 5.2 and 5.3 significantly improved energy efficiency and sound quality when using codecs like AptX or LDAC.
If you own Xiaomi, you might be wondering if your phone supports dual-device connectivity or low latency gaming, all of which are directly dependent on the hardware version of the chip. Older models may not be able to see the new features of modern headphones, even if they are technically compatible.
- 🎧 Compatible with high quality audio codecs for lossless music.
- 🔋 Energy consumption: new versions of Bluetooth significantly more economical consume battery power.
- 📡 Range and stability of the signal in conditions of noisy ether.
- 🎮 Low Latency is critical for gamers and users TWS-headphone.
In addition, knowledge of the version is necessary when selling a device or buying used equipment. Sellers sometimes indicate in the ads the characteristics of flagship models, forgetting to clarify that the budget Redmi has an older module.
⚠️ Note: Supporting a specific version of Bluetooth in the specifications on the box does not always guarantee all of its features. MIUI It may limit some of the possibilities.
Also, keep in mind that device drivers play an important role. Even if hardware supports the new standard, without an appropriate system update, the phone will run on the old protocol. So before checking the specifications, make sure that your device is updated to the latest available version.
Check through the standard Android settings menu
The easiest and safest way to get the primary information is through the standard operating system settings menu, but it’s worth noting that the pure version of the protocol (e.g. 5.1 or 5.2) is rarely displayed here. It usually shows the connection status or general details of connected devices, but it’s worth starting from here.
Xiaomi and Redmi owners need to go to the settings section to see a list of paired devices. If the phone sees devices that support new standards, this is an indirect sign of the relevance of the module.
☑️ The verification algorithm in the menu
Go to Settings → Bluetooth. Here you will see a list of available and paired devices. Click on the gear icon or arrow next to the name of the connected gadget. The menu that opens can display information about the profiles used (A2DP, AVRCP, HFP). Having a high-bitrate A2DP profile often indicates the presence of modern versions of the protocol.
You can also look at the "About the Phone" section, and the way is this: Settings. → The phone. → All specs (or "All specs"). In some versions of HyperOS, multiple clicks on "Version" MIUI" or “Android Version” opens an extended menu where information about the iron platform sometimes slips, although more often it concerns the processor and memory.
| Parameter | Where to find out. | What shows |
|---|---|---|
| Connection status | Settings → Bluetooth | Module activity |
| Profiles | Device properties | Types of data transmission |
| MAC-address | Device properties | Unique module ID |
| POS version | The phone. | Relevance of drivers |
If the standard menu doesn’t have exact numbers, don’t despair. This is normal for a MIUI shell that hides technical details from the average user. To get accurate data about the version of the specification (for example, Core Version 5.2) will require more in-depth methods, described below.
Use of third-party applications for diagnosis
The most reliable and easy way for the average user is to install specialized software from the Google Play Market. There are many utilities that read data directly from system files and output them in an understandable way, which eliminates the need to use a computer or enter complex commands.
One of the most popular and reliable tools is the Bluetooth Scanner app or Device Info HW. Once installed, the software is asked to access the location and the Bluetooth adapter, which is necessary to scan the airwaves and read the characteristics of its own module, and after launch, the application will show a detailed report.
- 📱 Device Info HW: Shows detailed hardware information, including the exact version of the Bluetooth chip.
- 🔍 Bluetooth Scanner: Specializes in signal analysis and supported profiles.
- 🛠 AIDA64: A comprehensive diagnostic tool that displays all system parameters.
- 📡 BLE Scanner: Useful to Verify Bluetooth Low Energy Support (BLE).
Run the app you select and find the section related to connectivity or network. The Bluetooth Version field will show you the number you want to see, for example, you can see the entry "Version: 5.1" or "Core Spec: 5.0." This is your current version. It's important to understand that the apps read the data that the module itself provides, so they show the real version, not the marketing version.
Why can apps show different data?
It's safe to use third-party software if you download it from official sources, but remember that free versions may contain ads. To check the Bluetooth version one-time, it's a perfectly acceptable solution. Once you get the information, you can delete the application so you don't have to take up memory.
⚠️ Note: When installing diagnostic gates, pay attention to the permissions requested. If a simple Bluetooth scanner requires access to contacts or SMS, refuse installation - this is a sign of malware.
Getting information through developer mode and ADB
For advanced users who want to get the most detailed technical information without installing unnecessary applications, there is a method using USB debugging, which allows you to “look” deeper into the Android system and get raw data from the Bluetooth stack.
First, you need to activate the developer mode. On Xiaomi and Redmi phones, this is done by pressing the "Version" item seven times. MIUI" In the "About the phone" section, when you get the "You're a developer" message, you go to the advanced settings and turn on "Debugging by" USB".
adb shell dumpsys bluetooth_managerConnect your phone to a computer with Android Debug Bridge installed (ADB). Open the command line or terminal on your PC and type the command above. It will output a huge log file with technical data. In this text stream, you need to look for lines containing "Version" or "Core".
An alternative is to use the command to derive the system properties:
adb shell getprop | grep bluetoothThis command will only filter out strings associated with Bluetooth, and ro.bluetooth.version or similar ones that point to a protocol version may be found, and some devices with MIUI may be able to hide these properties or replace them with stubs, so the method does not give a 100% guarantee of success on all models.
💡
The ADB method provides the most accurate technical data, but requires PCs, drivers and basic command line knowledge.
If you don’t want to mess with cables and command line, you can use the terminal directly on your phone. Install a terminal application (like Termux), get root rights (which is not recommended for ordinary users because of the risk of losing warranty), and type in the getprop command. However, on devices without root rights, access to some system variables through the terminal on the phone itself may be limited.
Analysis of the specifications of the processor and phone model
You often don't have to go into the wilds of settings if you know which processor is installed in your Xiaomi or Redmi. The Bluetooth module is usually built into a chipset (SoC) or rigidly tied to a Wi-Fi module of the same line. Knowing the processor model, you can pinpoint the Bluetooth version, because it's unchanged for a particular series of chips.
For example, Qualcomm Snapdragon 600 and 700 series processors released after 2020 are almost always equipped with Bluetooth 5.0 or 5.1. Budget chips MediaTek Helio can have version 4.2 or 5.0. To find out the model of the processor, just look at the characteristics of your model on the Internet or in the Settings → About phone application.
- 🚀 Snapdragon 8 Gen 1/2/3: Bluetooth guaranteed 5.2 or 5.3.
- 📉 Snapdragon 680/695: Bluetooth 5.0 or 5.1.
- 💎 Dimensity series: Modern models support 5.2+.
- 📉 Helio G series: often limited to 5.0 or even 4.2 versions.
There are official spec sheets from chip makers, and if you find documentation on your CPU (like the Snapdragon 732G for the POCO X3 NFC), you'll see the "Connectivity" line, which will specify the exact version, which is the most reliable way if the phone hasn't been bought yet or if the software methods fail.
You can also use the GSMArena website or the official Xiaomi website, and the "Comms" or "Comms" section always indicates the Bluetooth version, but be careful: sometimes the specifications specify the maximum possible version for a given chip, rather than the one that the phone manufacturer implemented in a particular model.
💡
If you know the exact model of your smartphone (like the M2101K7BNY), just type in Google the "model + specs bluetooth" query.
Compatibility table of Bluetooth versions
Understanding backward compatibility is important for users. Even if your Redmi has an old Bluetooth 4.2, it will be able to connect to new Bluetooth 5.3 headphones, but they will work in 4.2 mode.
| Version. | Year out | Speed (Mbps) | Range (m) |
|---|---|---|---|
| 4.2 | 2014 | 1 (LE 2.5) | ~50 |
| 5.0 | 2016 | 2 (LE 2.5) | ~200 |
| 5.1 | 2019 | 2 (LE 2.5) | ~200 |
| 5.2 | 2020 | 2 (LE 2.5) | ~240 |
| 5.3 | 2021 | 2 (LE 2.5) | ~240 |
As you can see from the table, the main jumps in performance occurred when switching to 5.0. Xiaomi’s current flagships are already moving to the 5.3 and 5.4 standard, which provide better performance in conditions of strong interference and a more stable connection when switching between devices.
If you notice that the phone often loses connection or the sound is interrupted, the problem may not be in the version, but in signal interference or software failure, in which case, resetting network settings or flashing the module through a system update helps.
