How to check the version of Bluetooth Xiaomi Redmi Note 8 Pro: all ways

Xiaomi Redmi Note 8 Pro is one of the most popular smartphones of the brand, but even its owners sometimes face the need to learn the technical characteristics of the device, which are not specified in the standard settings. The Bluetooth version is just such a parameter: it is important for compatibility with headphones, smart watches or car system, but the manufacturer rarely puts it in a prominent place.

In this article, we’ll look at all the ways you can determine the Bluetooth version on the Redmi Note 8 Pro, from simple (via standard menus) to advanced (using engineering mode or third-party utilities), and learn why this information can be useful, and what to do if your smartphone doesn’t recognize devices with the new Bluetooth 5.0+ protocols.

Important: The Redmi Note 8 Pro officially supports Bluetooth 5.0, but some regional versions (such as India) could have a chip with stripped-down features.

Why know the Bluetooth version on your smartphone?

At first glance, the Bluetooth version is a technical trifle, but in practice it affects:

• 🎧 Sound quality in wireless headphones (aptX codecs, AAC, LDAC It only works with Bluetooth 4.2.+).
• 🚗 Compatible with automotive systems (some multimedia centers require Bluetooth 4.1)+ for hands-free).
• 🕒 Energy consumption: new versions (5.0)+) Save battery power when connecting devices.
• 📶 Bluetooth 5.0 extends range to 40 meters (in theory).

For example, if your Sony WH-1000XM4 headphones support LDAC, but your smartphone is low-quality, the problem may be with an outdated Bluetooth version. Or vice versa: if the Redmi Note 8 Pro does not see the Mi Band 7 smartwatch, you may need a firmware update to activate support for new protocols.

Method 1: Check through MIUI settings (the easiest)

The most obvious method is to look at standard MIUI settings. Unfortunately, in most firmware versions, Bluetooth information is hidden, but it can be extracted indirectly.

1. Open the Settings app (cog icon).
2. Go to the About Phone section. → All characteristics.
3. Scroll down to the Network or Wireless Networks block.

If you're lucky, there's a Bluetooth version bar with a protocol (e.g. 5.0). However, MIUI 12-14 for the Redmi Note 8 Pro often doesn't have that option, so move on to the following ways.

💡

If the specifications only include a standard (e.g., “Bluetooth”) but not a version, it is a sign that the smartphone is using a basic protocol implementation (usually 4.2 or 5.0).

Method 2: Use of an engineering menu (for power users)

Engineering Mode is a hidden MIUI section that collects low-level device settings, including data about the Bluetooth module. Careful: wrong actions here can disrupt the smartphone.

To get there:

1. Open the Phone app.
2. Enter the combination: ##4636##
3. In the menu that appears, select Phone Information (or Hardware Testing in some versions).
4. Scroll to the Bluetooth block – there will be a string with the version (e.g. BT 5.0).

If the combination doesn’t work, try the alternative code:

##232338##

⚠️ Note: Do not change the settings in the engineering menu unless you are sure of their purpose. for example, reset Bluetooth settings (Reset) BT) It can cause the loss of connected devices.

Method 3: Third-party applications for diagnosis

If previous methods have failed, Google Play apps will come to the rescue, analyzing the hardware components of the smartphone and output detailed information, including the Bluetooth version.

The best tools for this task:

• 📱 AIDA64 — Shows the Bluetooth version in the System section → CIQ.
• 🔍 CPU-Z — SoC tab information (sometimes you need to scroll down).
• 🛠️ DevCheck – Hardware section → Bluetooth.
• 📊 Hardware Info – Connectivity tab.

An example of the mapping in AIDA64:

Important: If the app shows a Bluetooth version below 5.0, but the smartphone officially supports it, try updating the firmware to the latest version of MIUI. In rare cases, the problem is solved by resetting the network settings.

Method 4: Checking through ADB (for developers)

If you're familiar with the developer tools, you can find out the Bluetooth version through ADB (Android Debug Bridge), a method that requires connecting your smartphone to your computer.

Instructions:

1. Turn on USB debugging in the developer settings (Settings → About Phone → MIUI version → 7 times tap on the line).
2. Connect the Redmi Note 8 Pro to your PC and confirm the debugging permission.
3. Open the command line (or Terminal on Mac/Linux) and type in: adb shell getprop ro.bluetooth.version
4. Alternative command for detailed information: adb shell dumpsys bluetooth_manager

The answer will be a line of the type Bluetooth version: 5.0 or similar. If the team returned an empty result, try:

adb shell settings get global bluetooth_version

⚠️ Attention: Use ADB It requires Xiaomi drivers installed and Google’s Platform Tools package. some firmware may restrict access to Bluetooth properties.

What to do if the Bluetooth version is lower than expected?

If the check showed that your Redmi Note 8 Pro is running Bluetooth 4.2, although it should support 5.0, the reasons may be as follows:

• 🔄 Outdated firmware: Update MIUI Up to the latest version through Settings → Updating the system.
• 🌍 Regional restrictions: Some versions of the smartphone for India or China came with stripped-down modules.
• 🔧 Software failure: Reset network settings (Settings) → Wireless networks → Additionally. → Reset Wi-Fi, mobile network and Bluetooth).
• 🛠️ Hardware problem: Damage to Bluetooth antenna or controller (requires diagnosis at service center).

If the firmware update didn’t work, check your device model through Settings → About Phone → Model. For example, the Redmi Note 8 Pro for the global market (M1906G7G) should support Bluetooth 5.0, and the Indian version (M1906G7I) is sometimes limited to 4.2.

Check the firmware version.

Update MIUI to the latest version

Reset the network settings

Make sure there is no physical damage to the antenna.

Try connecting another device for the test.-->
