How to reconnect Bluetooth device on Xiaomi if pairing has been canceled

You removed your headphones, speakers, or fitness bracelet from Xiaomi's list of associated Bluetooth devices, and now you can't reconnect them? The system stubbornly ignores the gadget even though it's on and around? This problem is familiar to many MIUI smartphone owners -- especially after upgrades or resets. 80% of the time, it's not the faults, but the hidden limitations of the Bluetooth protocol or the system's cache.

Unlike the iPhone or Samsung, where re-pairing often takes place in a single click, Redmi smartphones, POCO and Mi can block the devices by MAC-We will discuss 4 working ways to return a connection, from basic to advanced (including) ADB And we will also find out why Xiaomi sometimes “forgets” gadgets after unmatching and how to avoid this in the future.

Why Xiaomi doesn’t see the device after removing the pairing

The problem lies in the specifics of implementing Bluetooth stack in MIUI, and here are the key reasons:

• 🔄 Bluetooth Cache: The system retains device data even after being removed from the list, which blocks re-detection.
• 📱 Limitations MIUI: Some of the scalings (especially) MIUI 12–14) there is a limit on the number of connected devices of the same type (for example, 5 headphones).
• 🔒 Lock-in MAC-Address: If the device previously connected via Secure Simple Pairing (SSP), The system can "remember" it as unsafe.
• 🔄 Profile conflict: Gadget tries to use old profile (e.g, A2DP It’s not sound, but the smartphone can’t see it».

On the Redmi Note 10 Pro and POCO X3 Pro, the problem most often occurs with devices that previously connected via BLE (Bluetooth Low Energy) - Mi Band fitness bracelets or Redmi Buds wireless headphones. In such cases, standard Bluetooth reset does not help - you need a comprehensive approach.

⚠️ Note: If the device previously connected to the smartphone through an application (for example, Mi Fit for Mi Band), remove it from the list of conjugated gadgets and in the application itself.

Method 1: Standard re-pairing (works in 60% of cases)

Start with the basic method – it works if the problem is not related to deep MIUI settings:

1. Open Settings → Bluetooth and make sure the module is enabled.
2. Click Add Device (the + or Search icon).
3. Turn on the pairing mode on your gadget (for example, press the button on the headphones before the indicator blinks).
4. Select the device from the list and confirm the connection.

If the smartphone does not find the gadget:

• 📴 Reboot both devices (smartphone and gadget).
• 🔄 Turn off/on Bluetooth on Xiaomi 2–3 times in a row.
• 📶 Make sure the distance between the devices is less than 1 meter (walls and interference reduce the range of action).

Remove the device from the list of conjugates (if it is still there)

Reboot the Bluetooth gadget (turn off/on)

Turn off VPN or plane mode on your smartphone

Check the battery charge of the gadget (below 20% can block pairing)

On the Xiaomi 12T and new models with MIUI 14, sometimes keeping the device name on the Bluetooth list helps, with a context menu with the option “Forget” (even if the gadget is already removed) that clears the hidden pairing data.

Method 2: Reset Bluetooth settings (works 85% of the time)

If the standard method doesn't work, reset the Bluetooth module settings, which will delete all the stored devices and cache:

1. Go to Settings → Applications → Application Management.
2. Press three points (⋮) in the upper right corner and select Show System Processes.
3. Find Bluetooth in the list and open it.
4. Click Warehouse → Clear the cache and Clear the data.
5. Reboot your smartphone.

After the reboot, try reconnecting the device, a method that is particularly effective for the Redmi 9 and POCO M3, where conflicts with Bluetooth 5.0 often occur.

💡

If Bluetooth is no longer on after reset, go to Settings → Memory → Clean up and optimize the system. This will restore the module.

⚠️ Attention: On Xiaomi with MIUI 13+ A Bluetooth reset can cause data loss in applications using this module (e.g. Google Fit or Strava.

Method 3: Manually remove the device through the engineering menu (for advanced)

If the smartphone persistently “does not see” the gadget, although it is turned on and is nearby, the problem may be in the list of blocked devices. MAC-To clear it:

1. Open the Phone app and type ##4636##.
2. Go to the phone information section.
3. Scroll down to the Bluetooth block and click Clear Device List (or Reset BT).
4. Reboot your smartphone.

On some models (Redmi K40, Mi 10), this method is not available – instead, use ADB:

adb shell pm clear com.android.bluetooth


adb shell rm /data/misc/bluedroid/bt_config.conf

Critical detail: After cleaning bt_config.conf All the associated devices will be removed without recovery, and this method should only be used if other methods have failed.

Method 4: Using ADB for forced reset (100% result)

This is the most reliable method, but it requires unlocking debugging over USB and your computer, and is suitable for all Xiaomi models, including the Redmi Note 12 and POCO F5:

1. Turn on Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your smartphone to your PC, install it ADB Tools and execute commands: Adb devices adb shell su rm /data/misc/bluedroid/bt_config.conf reboot

Once you reboot, all previous pairings will be erased, and you can reconnect the device, and this method is guaranteed to work even if:

• 🔌 Smartphone “does not see” gadget in range.
• 🔄 There is an error “I could not connect».
• 📵 The device flashes but does not appear in the list.

Frequent Mistakes and How to Avoid Them

Even after a successful connection, problems can come back, and here are the typical user errors and how to prevent them:

• 🔋 Low-charge gadget: Many Bluetooth devices (especially TWS-Headphones block pairing at a charge below 15%. Charge them before connecting.
• 📱 Conflict with other devices: If more than 3-4 gadgets are connected to the smartphone, new ones may not be identified.
• 🔄 Automatic Connection: In Bluetooth Settings → Additionally, disable the option “Auto-connection to audio devices” – it may interfere with manual pairing.
• 📲 Updates MIUI: After updating the firmware, reset the Bluetooth settings (see Method 2).

Xiaomi has a new feature with MIUI 14 called Smart Connection (in Bluetooth settings) that automatically connects devices based on location, but sometimes blocks manual pairing. Turn it off if there's a problem.

💡

If the device connects but the sound is coming through the smartphone speaker, check Settings → Sound → Output – the wrong profile may have been selected (e.g., Phone Call instead of Media).
