Today’s users often face the need for fast data transfer between a mobile device and a desktop computer. Although USB cables provide high speeds, they are not always at hand, and the use of cloud services requires a stable Internet. In such situations, Bluetooth wireless technology becomes an indispensable tool for rapid synchronization.
Xiaomi smartphones are equipped with advanced communication modules that allow you to easily organize data exchange with external devices. However, the pairing process can have its nuances depending on the version of the MIUI or HyperOS operating system, as well as the operating system installed on your PC. Understanding these subtleties will help avoid typical errors.
In this article, we will take a closer look at all the steps of connection setup, look at file transfer methods, and offer solutions to common problems, and learn how to make the connection process as fast and secure as possible using standard system tools without installing excess software.
Equipment preparation and software
Before starting the procedure, you need to make sure that both devices are ready to interact. The computer must have a working Bluetooth adapter (USB-Whistle, whereas laptops are built into the motherboard. Make sure the adapter drivers are updated to the latest version via Device Manager.
On the smartphone side, Xiaomi also needs to perform a number of preliminary steps: First of all, check if the wireless module is turned on in the notification curtain. For stable operation of the system, it is recommended that the Android versions on the phone and Windows on the computer be up to date, as the old protocols may not support new encryption standards.
⚠️ Warning: Make sure your Xiaomi device is not in “Invisibility” or “Shidden Mode” or your computer will not be able to detect it when scanning.
It's also worth checking the battery power of both devices, and finding and connecting, while energy efficient, is still a resource-consuming process, and if the phone is zero, it may not be able to complete the pairing process.
💡
Keep devices no more than 1-2 meters apart during initial pairing for better signal quality.
Turning on Bluetooth on Xiaomi smartphone
There are several ways to activate a function on a mobile device, and the fastest way is to lower the top curtain of the menu and click on the Bluetooth icon, and if the icon is blue, the module is activated, but that's not enough to adjust the visibility.
You need to go to the full system settings. To do this, select Settings in the app menu, then search for the Bluetooth section. Here you will see the list of available devices and your phone's visibility switch. Make sure that the "Appears All" slider is active if you want the PC to find the phone manually.
In newer versions of the MIUI shell, the interface may be slightly different. Sometimes the visibility settings are hidden in an additional menu that is called by clicking on a gear or three dots in the corner of the screen. Owners of the Redmi Note or Xiaomi Mi series should pay attention to the name of the device - it is better to change it to recognizable, so as not to confuse it with other gadgets in the list.
Setting up Bluetooth in Windows
Windows provides flexible tools for managing wireless connections. Windows 10 and 11 standardize the process. Open the Start menu and go to Settings (cog icon). Next, select Devices or Bluetooth and devices depending on the OS version.
Make sure the Bluetooth switch is in the "On" position. If the button is gray and not active, it is possible that the adapter driver is not installed or the device is physically disabled. In this case, check the Device Manager, find the "Bluetooth Radio Modules" section and make sure there are no exclamation signs next to the equipment.
To add a new gadget, click Add Bluetooth or another device. In the window that opens, select the first item, "Bluetooth." The system will start searching for available devices within range, a process that can take from seconds to minutes.
☑️ Checking Windows settings
The process of pairing devices
When the computer starts searching, your Xiaomi smartphone name should appear on the list of available devices. Click on it with the left mouse button. A system window will pop up on the phone screen with a pairing request and confirmation code. A similar window will appear on the computer monitor.
Compare the digital codes on both screens. If they match, click Connect on your PC and Confirm (or tick) on your phone. Once authenticated successfully, the device status will change to Connected. Now the gadgets know each other and can share data.
Sometimes the system may ask permission to access contacts or call histories, which is standard procedure for synchronizing a user's profile, and you can either agree or refuse, depending on whether you plan to use the computer as a headset or simply to transfer files.
| Status | Action on the PC | Action on Xiaomi | The result |
|---|---|---|---|
| Search | Press "Add device" | Turn on visibility | Display of name on list |
| Request. | Click on your name | It'll come in code. | Waiting for confirmation |
| Verification | Compare the numbers | Compare the numbers | Secure connection |
| Finals. | Press "Connect" | Press "OK." | "Connected" status |
⚠️ Warning: Never confirm the pairing code unless you initiated the connection yourself, as this may be an attempt at unauthorized access.
File transfer and management
Once paired successfully, you can transfer data. Windows uses a built-in utility to do this. Open Start, search for "Send or File via Bluetooth" (or "Bluetooth File Transfer") and run the application. Select the "Get Files" option so that the PC can expect the incoming data stream.
On a Xiaomi smartphone, select a file (photo, document, video), click the Share button and select Bluetooth from the list of methods. Find your computer name in the list and confirm the sending. A notification will appear on the PC screen about the incoming file - it must be accepted, otherwise the transfer will fail.
Transfer speeds vary depending on the protocol version. Bluetooth 4.0 is about 2-3 Mbps, and Bluetooth 5.0 can reach 24 Mbps under ideal conditions. For large data volumes (4K video or gigabyte archives), this method can be slow, but for documents and photos it is quite convenient.

Addressing common problems
It's not always the first time you get a connection. One of the common problems is that the computer sees the phone but doesn't connect. In this case, try removing the device from the list of stored devices on both devices and repeating the procedure again. Often, a simple reboot of the Bluetooth module on the phone (turn it off and on) helps.
Another problem is the lack of drivers. If Windows Device Manager displays "Unknown Device," download drivers from the laptop or adapter manufacturer's website. Xiaomi phones sometimes require ADB drivers to be installed, although this is rarely necessary for basic file transfers.
It is also worth checking the energy saving settings. USB-The port to which the Bluetooth adapter is connected. Windows can turn it off to save power. In Device Manager, find your Bluetooth adapter, go to properties, tab "Power management" and uncheck "Allow this device to turn off".
💡
Rebooting both devices and removing the old pairing profile solves 90% of connectivity problems.
Alternative methods of wireless communication
If classic Bluetooth doesn’t suit you, the Xiaomi ecosystem offers other solutions: Wi-Fi Direct allows you to transfer files at speeds up to 50-100 Mbps without using a router, and you can use Microsoft’s “Phone Link” app on your PC or MIUI+, a proprietary utility now part of the HyperOS Connect ecosystem.
Another option is to use cloud services like Google Drive, Mi Cloud or Yandex.Disk. By uploading a file to your phone, you instantly access it from your computer through a browser. This does not require a direct connection of devices, but consumes Internet traffic.
For advanced users, there is an FTP protocol over Wi-Fi. The standard MIUI Explorer has a Network Access function. By turning it on, you get an address (e.g., ftp://192.168.1.5:212121) that you can type into the address bar of My Computer in Windows, which gives you full access to the entire file system of the phone at high speed.
⚠️ Attention: When using open source FTP-In public Wi-Fi networks, your data can be intercepted. Use this method only on trusted home networks.
