How to Reset Bluetooth on Xiaomi Smartphones: A Complete Guide with 5 Working Methods

Bluetooth on Xiaomi smartphones is one of the most capricious modules, often getting stuck with MIUI updates, connecting new devices, or even for no apparent reason. The problems range from the inability to find headphones to the constant breakdown of the connection with smartwatches or speakers. In 80% of cases, resetting Bluetooth settings helps - a procedure that returns the module to factory parameters without losing data on the phone itself.

In this article, we’ll look at 5 proven Bluetooth reset methods, from standard MIUI menus to hidden engineering commands and tools for power users. You’ll learn how to reset the module cache, remove all paired devices at once, and what to do if Bluetooth doesn’t turn on at all. The instructions are relevant for all modern Xiaomi, Redmi and POCO models (including Xiaomi 13/14, Redmi Note 12, POCO F5 and others).

Before you start, check the basics: Bluetooth may not work due to a battery drain (less than 15%), active mode "Save charge" or conflict with a VPN.

1. Standard Bluetooth reset via MIUI settings

The safest and most recommended way is to use the built-in MIUI tools. It is suitable for most users and does not require super-user rights (root).

1. Open the Settings app (cog icon).
2. Go to Connections and Sharing (or Bluetooth in older versions of MIUI).
3. Click on the three dots in the top right corner and select Bluetooth Settings.
4. Scroll down and tap on Reset Settings (or Clear cache in some firmware).
5. Confirm the action by pressing OK in the dialog box.

Once reset, the phone will automatically restart the Bluetooth module, and all previously paired devices will be removed and reconnected, which works on MIUI 12/13/14 and newer, including global and Chinese firmware.

⚠️ Warning: If Bluetooth still doesn't turn on after reset, check if the module is disabled in Flight Mode or via Quick Settings (swipe down from the top of the screen.

2. manual removal of all paired devices

If resetting through settings didn't work, try to clear the list of paired devices completely. Sometimes the conflict arises because of damaged connection profiles (especially after MIUI updates).

1. Go to Settings → Connections and Sharing → Bluetooth.
2. Click on the gear icon next to each device in the list.
3. Select Disable, then Forget this device (or Delete).
4. Repeat for all devices.

After removing, restart your phone (required!) Then try reconnecting your headphones or other device, a method that often solves problems with connection breaks or lack of sound in your headphones.

If the list of devices is empty, but Bluetooth still does not work, move to the next method - cleaning the cache of the system.

💡

Once you remove the devices, try to reconnect them, first the ones that were less common, and this helps to avoid conflicts when you re-match.

3. Cleaning the Bluetooth cache through "Applications"

The Bluetooth module in MIUI works as a standalone system application, and its cache can clog up, causing crashes.Cache cleaning often solves problems with constant device searches or inability to connect.

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the upper right corner and select Show System Processes.
3. In the search bar, type Bluetooth.
4. Select the Bluetooth app (or Bluetooth MIDI Service in some firmware).
5. Click Clear cache and Clear data (if available).
6. Reboot the phone.

Important: On some models (like the Redmi Note 10 Pro), Bluetooth may temporarily disappear from the Quick Settings menu after cleaning up the data.

4. Reset via engineering menu (code ##4636##)

For power users, there is a way to reset through the hidden engineering menu.It works on most Xiaomi models, but requires caution - don't change the other settings on this menu!

Instructions:

1. Open the Phone app.
2. Enter the code ##4636## (on some firmwares, see the alternative below).
3. In the menu that opens, select Phone Information (or Usage Statistics).
4. Scroll down and find the Bluetooth section.
5. Click Reset Settings or Clear BT config.
6. Reset the device.

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

1. Install the MTK Engineering Mode application from the Play Market (MediaTek processors only).


2. Open it and go to the Connectivity section.




3. Select "Bluetooth" and press "Reset".

⚠️ Note: On smartphones with Qualcomm Snapdragon processors (for example, Xiaomi 13 Pro, POCO F5 Pro) the engineering menu may be missing or have a different interface. Do not change the settings unless you are sure of their purpose!

5. Bluetooth reset via ADB (for advanced users)

If standard methods don't work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to execute system commands, which requires a computer and minimal technical skills.

Step-by-step:

1. Download and install ADB Tools on your computer.
2. Turn on USB Debugging on your phone: Go to Settings → About Phone. Tap 7 times on MIUI to activate Developer Mode. Go back to Settings → Additional → Developer. Enable USB Debugging.

File transfer

Open the command prompt (Windows) or terminal (Mac/Linux) in the folder with ADB.

adb devices


adb shell




su




pm clear com.android.bluetooth




reboot

(If you request root rights but don’t have them, skip the su command.)

After the reboot, Bluetooth will be completely reset, which is effective if the problem is caused by corrupting system files or firmware conflicts.

6. Hardware reset (if Bluetooth is not turned on at all)

In rare cases, the Bluetooth module can shut down completely at the hardware level — for example, after a phone drops or moisture hits. If none of the above methods worked, try:

• 🔌 Hard reboot: Press the power button + Increase volume by 10-15 seconds until the phone restarts.
• 🔧 Antenna check: If the phone is disassembled, make sure that the Bluetooth plume (usually combined with Wi-Fi) is tightly connected.
• 📱 Test in Safe Mode: Press the Power button → Safe Mode. If Bluetooth is working, the problem is in the third-party app.
• 🔄 Resetting to factory settings: a last resort if other methods didn't help (Settings) → The phone. → Resetting settings).

If Bluetooth still doesn’t work, you may need to replace the module (in the service center) or flash it through Fastboot (for power users).

💡

Before visiting the service center, check the warranty – on most Xiaomi models, the Bluetooth module is covered by the warranty for 12 months.
