Connecting Lenovo Tablet to Xiaomi Phone via Bluetooth: The Complete Guide

Why sync Lenovo and Xiaomi over Bluetooth

Pairing a Lenovo tablet with a Xiaomi phone via Bluetooth opens up possibilities that many users don’t even know about: You can transfer files without the Internet, use the tablet as an additional screen for calls, synchronize alarms or even control music on your phone from a large screen, especially for owners of Lenovo Tab (P11 series, M10) and Xiaomi smartphones on MIUI 14/15, where Bluetooth 5.2+ supports low power consumption and high transfer speeds.

However, in practice, users face typical problems: devices can’t see each other, connections are constantly broken or files are transmitted with errors, the reasons lie in different versions of Bluetooth (for example, the Lenovo Tab P11 Pro is equipped with a module 5.1, and the Xiaomi 13 Pro – 5.3), conflict connection profiles or outdated drivers. In this article, we will discuss not only the basic connection, but also the unique MIUI settings for stable work with Lenovo tablets, which are missing from standard instructions.

Device Preparation: Compatibility Checking and Updating

Before you start pairing, make sure that both devices support the necessary protocols. Most modern Lenovo tablets (released after 2020) and Xiaomi smartphones (Redmi Note 10+ series, POCO X4, Xiaomi 12/13) are equipped with Bluetooth 5.0+, but there are nuances:

• 🔍 Lenovo Tab M10 Plus (3rd generation) – Bluetooth 5.0, maximum transfer speed of 2 Mbps.
• 🔍 Lenovo Yoga Tab 13 – Bluetooth 5.2 with support LE Audio (low power consumption).
• 🔍 Xiaomi 11T Pro – Bluetooth 5.2, but with proprietary extensions for Mi TrueWireless headphones.
• 🚫 Lenovo Tab 4 (Bluetooth 4.2) may not support some features MIUI.

Update the firmware on both devices:

1. On Xiaomi: go to Settings → About Phone → System Update.
2. On Lenovo: Settings → System → Software Update.

Critical error: If Xiaomi has custom firmware installed (e.g. Pixel Experience), the standard Bluetooth driver can be replaced with an unstable one, in which case, reset the network settings before pairing:

Settings → Additional → Resetting → Resetting Wi-Fi, mobile network and Bluetooth settings

Step-by-step: pairing Lenovo and Xiaomi

The algorithm for the connection is simple, but in practice, 30 percent of users experience a "failed to connect" error.

1. Activate Bluetooth on both devices: On Xiaomi: swipe down → long tap on the Bluetooth icon → turn on. On Lenovo: Settings → Connections → Bluetooth → switch to the “On” position.
2. Start a device search: On Xiaomi, click "Device Search." On Lenovo, select "Add New Device."

Confirm the pairing code

• Both screens will have the same 6-digit code (e.g., 123456 or 874321).
• Confirm the connection on both devices.

If the devices don’t find each other, try:

• 🔄 Reboot Bluetooth module: Disable and turn it on on on both devices.
• 📱 On Xiaomi, turn off the dual Bluetooth connection function (in Bluetooth settings).
• 🔧 On Lenovo, reset your network settings: Settings → System system → Reset → Reset Wi-Fi, mobile network and Bluetooth.

⚠️ Note: If Xiaomi has Bluetooth Debugging Mode enabled, the pairing may be blocked. Turn off debugging in Settings → The phone. → Version. MIUI (5 times press) → Developer settings → Bluetooth debugging.

Advanced settings: Connection optimization

Basic pairing isn't enough for stable operation, and MIUI has hidden settings that improve connectivity with Lenovo tablets:

To access hidden Bluetooth profiles on Xiaomi:

1. Activate Developer Mode (5 times click on the MIUI version in your phone settings).
2. Go to Settings → Additional → Developer settings.
3. Find Bluetooth Settings and select A2DP Profiles.
4. Mark SBC and AAC (disable aptX if the tablet doesn’t support it).

💡

If the connection breaks when transferring large files, reduce the MTU (Maximum Transmission Unit (BUTU) to Bluetooth 512 bytes via the adb shell command btmtk_set_mtu 512. This requires root rights or ADB-access.

File Transfer: Bypassing MIUI Restrictions

By default, MIUI blocks file transfers over Bluetooth "for security reasons." To unlock this feature:

1. On Xiaomi, open Files → Categories → Local Storage.
2. Select a file, click "Share" → "Bluetooth".
3. If you don’t have an option, install a side app (like Send Anywhere or Files by Google).

The alternative way is to use FTP-Bluetooth:

• 📲 On Lenovo, install Bluetooth File Transfer (available on Google Play).
• 🔗 On Xiaomi, connect to the tablet as if to FTP-server ES Conductor or Solid Explorer.
• 📁 Transfer speed will reach 1.5-2 Mbit / s (versus 0.5 Mbit / s in standard exchange).

⚠️ Note: When transferring files in volume >500MB via Bluetooth Xiaomi can automatically disable the connection.Separate files into pieces or use RAR-archiving by volumes of 300 MB.

Troubleshooting: Why it doesn’t connect

If the pairing fails, check the following points:

For diagnostics, use the hidden Bluetooth log on Xiaomi:

adb logcat | grep -i bluetooth

If the log has GATT error or Connection timeout, the problem is hardware incompatibility modules, in which case only updates to the firmware or the use of alternative protocols (for example, Wi-Fi Direct) will help.

💡

If none of these methods worked, try connecting via Mi Share (a built-in feature of Xiaomi for transferring files over Wi-Fi Direct).It works more stable than Bluetooth and supports speeds of up to 10 Mbps.

Alternative ways to connect Lenovo and Xiaomi

If Bluetooth refuses to work, consider alternatives:

• 🌐 Wi-Fi Direct: Speed: up to 25 Mbps How to connect: Settings → Wi-Fi → Wi-Fi Direct on both devices.
• 🔌 USB-OTG + cable: Speed: up to 480 Mbps (USB How to connect: cable is required USB-C to USB-C And file transfer mode on Lenovo.
• ☁️ Cloud services: Mi Cloud or Google Drive for sync, plus: access from any device.

To stream your screen from Lenovo to Xiaomi, use ApowerMirror or TeamViewer QuickSupport.These apps work over Wi-Fi, but Bluetooth pairing may be required to set up initially.
