Modern smartphones Xiaomi And Redmi have extensive functionality for wireless data transfer, but the standard Android settings often hide direct control of the protocol Wi-Fi DirectUsers often encounter situations where they need to quickly transfer a large file or display an image on the screen, but the familiar switch is missing from the menu. This is due to the specifics of the shell. MIUI And HyperOS, which prioritize their own ecosystem solutions.
However, the protocol itself has not gone anywhere and is actively used by the system to operate such functions as Mi Share And CastUnderstanding how to activate and use this technology "under the hood" gives device owners significant advantages in data transfer speed without compressing quality. In this article, we'll explore all the nuances of how this technology works on devices from this Chinese brand.
Unlike classic Bluetooth, which can be slow for video files or cloud storage that requires the Internet, Wi-Fi Direct Creates a direct connection between devices. Transfer speeds can reach tens of megabits per second, making the process virtually instantaneous. Let's look at how to make this mechanism work effectively on your device.
What is Wi-Fi Direct and why is it needed on Xiaomi?
Wi-Fi Direct — is a wireless communication standard that allows devices to connect directly to each other without the need for an access point or router. In the context of smartphones Xiaomi This technology is the foundation for many system functions. When you try to send a photo through the built-in gallery menu, the phone automatically uses this protocol, ensuring high speed.
The main advantage of this technology is that it eliminates the need for authorization using complex passwords, as is the case when connecting to a Wi-Fi network. The devices find each other automatically within a radius of up to 200 meters in open areas., which significantly simplifies data exchange in the field or in the office. This is especially important when the internet connection is busy or unavailable.
It is worth noting that on devices Redmi And Poco This protocol also powers the "Cast" feature, allowing you to display your smartphone's screen on a TV or projector. Without an active Wi-Fi Direct module, these features would be impossible or unreliable. So, even if you don't see a separate button, the technology is working in the background, enabling communication between devices.
- 🚀 High data transfer speed, exceeding the capabilities of Bluetooth by 10-20 times.
- 🔒 WPA2 connection encryption ensures the protection of transmitted information.
- 📡 Possibility to connect several devices simultaneously to one group.
- 🔋 Energy efficiency compared to constantly searching for Wi-Fi networks.
It's important to understand that although the physical module is single, it can logically operate in different modes. The smartphone can simultaneously broadcast internet, be connected to a router, and maintain a Wi-Fi Direct connection, although in the latter case, temporary interruptions in the primary connection may occur due to frequency switching.
Where to find the setting in MIUI and HyperOS
Users migrating from other brands or older versions of Android often look for a separate item in the settings menu. However, in modern skins MIUI 12, 13, 14 and new HyperOS developers Xiaomi removed direct access to the switch Wi-Fi DirectThis is done to simplify the interface, since the system itself manages the connection at the right moment.
Essentially, it's enabled automatically when you launch compatible apps. You don't need to manually activate the mode deep within the menu. It's enough to have the main wireless module and geolocation enabled, as in newer versions of Android, finding devices requires access to coordinates to scan their surroundings.
⚠️ Note: The lack of a visible "Wi-Fi Direct" toggle in the notification shade or main settings on Xiaomi devices is not a bug or an error, but a design feature. Don't try to find it in the settings search; you won't find it there.
To activate the necessary services, you need to go to the basic settings. The path usually looks like this: Settings → Wi-FiThe enable slider should be active here. The system will then decide when to enable the direct protocol. If you are using older models, such as the Redmi Note 8 or Mi 9, the logic of operation remains the same, but the interface may differ slightly.
Sometimes users confuse this feature with tethering. Tethering creates an access point to which others can connect, while Direct creates a peer-to-peer network between devices. Xiaomi Direct connections are handled by specific system services that are hidden from the eyes of the average user, but are available for calls by applications.
Using Mi Share to transfer files directly
The main tool that implements the capabilities Wi-Fi Direct on smartphones Xiaomi, is a function Mi Share (formerly known as Mi Drop). This is Apple's AirDrop counterpart, but it runs on Android. This service enables fast file transfers and activates the required communication protocol.
To start transferring, make sure Bluetooth and Wi-Fi are enabled on both devices. You don't need to configure any complicated settings; simply open your gallery or file manager. Select the file you want, click the "Send" button, and select Mi ShareThe phone will automatically start searching for available devices nearby.
Mi Share setup requires a few simple steps. First, you need to enable device visibility so others can find you. This can be done through the Control Center or in the feature's settings. Once the target device is detected, you'll be asked to confirm file transfer, ensuring data security.
- 📂 Support for transferring files of any type: photos, videos, APKs, documents.
- ⚡ Transfer speeds up to 100 MB/s under ideal conditions.
- 🌐 Works without internet or mobile data.
- 🔄 Transfer between different brands is possible (if a compatible client is installed).
If you can't find the function, check the "Tools" folder on your desktop. A system app is often hidden there. Mi ShareIn new versions HyperOS The integration has become deeper, and control is available directly from the notification shade (the "Mi Share" or "Exchange" item).
☑️ Setting up Mi Share
Screencasting via Cast and Wi-Fi Direct
Another area of application of the technology is the transmission of images to large screens. Function Cast (Broadcast) on smartphones Xiaomi It's also based on direct connection protocols. This allows you to wirelessly display images from your phone to a TV that supports Miracast or DLNA.
To get started, the TV and smartphone must be in the same location. While classic Cast requires a shared Wi-Fi network, many modern TVs allow you to connect directly via Wi-Fi Direct if a router is unavailable. This can be accessed through the "Wi-Fi Direct" option in the phone menu. Settings → Connection and Sharing → Broadcast.
When searching for devices, the phone scans the airwaves for available displays. If your TV isn't showing up, it may not be in reception mode. On remotes Samsung, LG or Sony There is often a separate "Input" button or "Screen Share" app that needs to be launched.
⚠️ Note: When streaming via Wi-Fi Direct, image quality may be affected by interference. If the picture is choppy, try moving closer to the TV or removing any obstacles between the devices.
It's important to note that some content-protected apps (such as Netflix or Kinopoisk) may block streaming using simple methods due to HDCP protection. In such cases, the system may suggest using Chromecast built-in, which requires a shared Wi-Fi network rather than a direct connection.
For gamers or presentations, input lag can be critical. Wi-Fi Direct offers lower latency than router-based transmission, as data travels directly, bypassing unnecessary switching nodes. This makes it the preferred method for displaying dynamic content.
Third-party connection management applications
Because Xiaomi Since the native control interface has been hidden, advanced users can resort to third-party software. There are apps that allow you to see hidden Android settings and force the mode to activate. Wi-Fi Direct for specific tasks, such as connecting gamepads or specialized equipment.
One of the popular solutions is the application WiFi Direct File Transfer or similar apps from Google Play. They don't require root access and provide a user-friendly interface for selecting files and searching devices. These utilities often run faster than standard tools because they lack cumbersome shell add-ons. MIUI.
Also worth mentioning is the app SuperBeam or Send AnywhereThey use the same operating principle, but add cross-platform support. You can transfer a file with Xiaomi on an iPhone or Windows PC using a QR code or digital key. The underlying principle is still to create a local network via a Wi-Fi module.
| Application | Connection type | Speed | Peculiarities |
|---|---|---|---|
| Mi Share (Native) | Wi-Fi Direct | High | Built-in system, the best choice for Xiaomi |
| Send Anywhere | P2P / Server | Average | Works online and locally, cross-platform |
| WiFi File Transfer | HTTP / FTP | Depends on the router | Requires a shared network, convenient for managing files from a PC |
| Nearby Share | Wi-Fi Direct / BLE | High | Google standard, replaces Mi Share on new versions |
Using third-party software is especially important if you need to connect a device that isn't supported by the system's standard tools. For example, some industrial printers or cameras have specific protocol implementations that are only visible to specialized applications.
Third-party application security
By using third-party file transfer apps, you grant them access to your gallery and file system. Always download software only from the official Google Play store, check permissions and reviews, and avoid apps with suspiciously high permission requests that aren't relevant to their functionality.
Typical problems and solutions
Despite the well-established technology, users Xiaomi may encounter difficulties. The most common issue is that devices don't see each other. In 90% of cases, this can be resolved by enabling geolocation (GPS). Android requires this permission to scan for networks, and without it, the list of available devices will be empty.
Another common error is a transfer being interrupted mid-process. This can occur due to an aggressive power saving policy. MIUIThe system may "kill" background transfer processes, considering them unnecessary power consumers. To avoid this, you should pin the app to memory or remove battery restrictions.
To set up exceptions, go to Settings → Battery → App power managementFind the app you're using (e.g., Mi Share) and select "Unlimited" mode. This will ensure the transfer process remains stable even if the phone's screen goes dark.
- 📶 Make sure Wi-Fi is turned on on both devices (even without a network connection).
- 📍 Check the location access permission for the transfer app.
- 🔋 Disable power saving mode when transferring large files.
- 🔄 Restart the Wi-Fi module (turn it on/off in the curtain).
If the problem persists, try resetting your network settings. This will reset your Wi-Fi, Bluetooth, and mobile network settings to factory defaults, deleting saved passwords and pairings, but it often resolves software and driver conflicts.
⚠️ Note: Resetting network settings will delete all saved Wi-Fi passwords. Make sure you remember your home network access details or write them down before performing this operation.
Frequently Asked Questions (FAQ)
Is it possible to transfer files from Xiaomi to iPhone via Wi-Fi Direct?
Directly via the native Wi-Fi Direct protocol—no, as Apple uses its own proprietary AirDrop standard. However, you can use cross-platform apps like Send Anywhere or web services like Snapdrop, which work through a browser and utilize the same local network principle.
Does Mi Share use up mobile data?
No, mobile data (3G/4G/5G) is not consumed. Data transfer occurs directly between devices via Wi-Fi. Internet access may be required only for the initial download of contact avatars or updating the device list, but the file itself is transferred over a local connection.
Why does the transfer speed drop to 1-2 MB/s?
This can happen if the devices are far apart, there are physical obstacles (such as walls), or if one of the smartphones is in power-saving mode. Speed may also drop if there's active internet downloading going on at the same time.
Does Wi-Fi Direct work if the phone screen is off?
In most cases, no. The screen goes dark, and after a few seconds, the system pauses background activity to save battery, which breaks the connection. Background streaming requires a special setting in the battery menu or the use of special services.
Do I need root to enable hidden Wi-Fi settings?
For basic use of Mi Share and Cast, root access is not required. It may only be necessary for deep modification of system files or using specific engineering menus, which is generally unnecessary for the average user and may void the warranty.
