Today’s Xiaomi smartphones feature a host of wireless connectivity modules that are often underrated by users, one of which is Wi-Fi Direct, which allows you to transfer files at high speeds without having to connect to a router. Device owners often look for a way to activate this feature, unaware that the shell is in the device. MIUI It is hidden under other names or integrated into system applications.
The main difficulty is that the standard switch in the "curtain" notifications for this mode is usually not. Android system and the proprietary add-on from the Chinese manufacturer use more intelligent algorithms for detecting devices. Understanding the principles of this protocol will help you to establish data exchange between gadgets as efficiently and quickly as possible.
In this article, we will discuss in detail where to look for settings, how to force the search of devices and what alternative methods of data transfer offers the Xiaomi ecosystem.
The principle of technology on Xiaomi devices
Wi-Fi Direct technology creates a direct peer-to-peer connection between two devices, bypassing the need for an access point. Unlike classic Bluetooth, it uses a wider data channel, which provides speeds of up to 250 Mbps and higher. For Xiaomi owners, this means the ability to transfer video to 4K or huge archives in seconds.
It's important to understand that on smartphones of this brand, the feature often works in the background. When you try to send a file through the system menu "Share", the operating system automatically scans the environment for compatible devices. If there is another phone nearby with an active screen, the connection is established instantly.
The protocol uses WPS (Wi-Fi Protected Setup) to pair securely, meaning that even without access to the global network, data is transmitted over a secure channel, but unlike conventional Wi-Fi, one device temporarily takes on the role of a router, which can cause a connection to the home network to break during active transmission.
Technical details of the protocol
Where to find Wi-Fi Direct settings in MIUI
Users are often baffled by the lack of an explicit button in the settings menu, and Xiaomi engineers have decided to integrate the management of this protocol into system file transfer services, and to access hidden settings, you need to use an engineering menu or special applications.
The standard way through settings is to go to Settings → Connection and Sharing. Here you will find items related to data transfer, but there will be no direct switch for Wi-Fi Direct. Instead, the system suggests using the Mi Share or Mi Drop feature (in older versions of firmware), which are based on this technology.
For more advanced users, there is a way to activate via a hidden debugging menu. This requires several times clicking on the MIUI version number in the About Phone section to activate developer mode. Then in the advanced wireless settings, you can find the option “Wi-Fi Direct”, which allows you to see all available devices within range, even if they are not Xiaomi gadgets.
Instructions for inclusion through Mi Drop and Mi Share
The most common way to use direct connectivity is the built-in Mi Drop app (renamed Mi Share in new versions), a regular tool that does not require additional software installation and is optimized to work with the hardware of the smartphone.
To get started, do the following: Open the app on both devices. Make sure both smartphones have Wi-Fi and Bluetooth enabled, as they are used for initial handshake and detection. Press the "Get" button on the receiving device and "Send" on the transmitter.
The system will automatically start a search, and when the devices detect each other, the avatar will appear on the screen, and after the connection is confirmed, the transmission will begin on both screens, and it is important to keep the screens on and not switch to other heavy applications, so as not to interrupt the process.
☑️ Preparation for file transfer
⚠️ Warning: When you use Mi Share actively, the Wi-Fi hotspot may temporarily shut down. Don't panic if the Internet goes missing - this is the standard behavior of the protocol that prioritizes direct connection between devices.
Use of third-party applications for activation
If Xiaomi’s built-in tools don’t work for some reason or you need to connect to a device that doesn’t support the Chinese brand’s proprietary protocols, you can use third-party software. There are many utilities in the Google Play store that give direct access to the Wi-Fi Direct API.
One popular solution is the WiFi Direct File Transfer app, which asks for permissions to access geolocation and network once installed, and then when it's launched, it scans the airwaves and shows you a list of available devices, and it's particularly useful when transferring files to Smart TVs or printers that aren't visible in the standard Share menu.
Another option is to use file managers with protocol support, such as File Commander or ES Explorer (older versions), which often have a "Network" or "Access from PC/Devices" section on their menus where you can initiate group creation, which allows you to turn your Xiaomi into a kind of server for distributing files.
💡
If a third-party app can't see the device, try manually disabling and turning on In-Air mode, which will restart network modules and clear the connection cache.
Comparison of data transfer methods on Xiaomi
The choice of transfer method depends on the file type and the receiver. Xiaomi ecosystem offers several options, and it is important to understand the differences so as not to waste time on slow Bluetooth where you can use a high-speed channel.
Below is a table comparing the main characteristics of the available connection methods. Pay attention to the speed and need of Internet connection.
| Method | Speed (max) | We need the Internet. | Compatibility |
|---|---|---|---|
| Bluetooth | up to 3 Mbps | No. | Universal. |
| Wi-Fi Direct (Mi Share) | up to 250 Mbps | No. | Android / MIUI |
| QR-code (HTTP) | Depends on the router. | Yes (locally) | Any browser |
| USB Cable | up to 480 Mbps | No. | PC/Laptop |
As you can see from the table, Wi-Fi Direct is the optimal balance between speed and convenience. It requires no wires and works much faster than classic Bluetooth. However, it is sometimes easier to use cable or cloud services to transfer files to a computer if the devices are on the same network.
Solving Connection Problems
Despite the reliability of the technology, Xiaomi users can face difficulties, often the device simply “can’t see” the interlocutor or the connection is cut off in the middle of the transfer, the first reason is usually the settings of energy saving.
MIUI aggressively optimizes battery consumption and can kill background network scanning processes. To avoid this, go to the battery settings, find the application that is being transmitted (such as Mi Share or file manager), and set the No Limits mode, which will prevent the system from turning off the Wi-Fi module while the application is running.
The second common problem is protocol version conflict: If you’re trying to pair a very old smartphone with Xiaomi’s new flagship, they may not “understand” each other due to differences in WPA2/WPA3 encryption standards, in which case you might try updating the firmware on both devices or using middleware.
⚠️ Attention: When transmitting large amounts of data, the smartphone case can warm up noticeably. This is a normal physical reaction of the Wi-Fi module to a high load, but it is better to remove the case for better heat sink.
💡
90% of connectivity problems are solved by restarting Wi-Fi and Bluetooth modules or removing power saving restrictions for the transmitter application.
