Modern smartphones of the brand Xiaomi have a wide range of functionality, which is often hidden deep within system settings. One such useful, but not always obvious, feature is Wi-Fi DirectThis technology allows devices to exchange data at high speeds without the need to connect to a hotspot or use mobile data.
Many users mistakenly believe that transferring files between phones requires internet or Bluetooth, which works quite slowly. However, P2P protocol (Peer-to-Peer) provides much higher transfer speeds, which is critical when working with high-resolution video files or large archives.
In this article, we will take a detailed look at where to find this function in the shell. MIUI or HyperOS, how to properly initiate a connection, and what to do if devices can't see each other. Understanding how wireless networks work will help you use your device's capabilities more effectively.
What is Wi-Fi Direct technology and why is it needed?
Wi-Fi Direct Wireless LAN is a standard that allows two devices to connect directly to each other without a wireless router. Unlike a traditional connection, where all devices rely on a central access point, the smartphone itself creates a mini-network for data transfer.
The main advantage of the technology is speed. If Bluetooth While Wi-Fi is limited by a narrow transmission channel, direct Wi-Fi can achieve speeds comparable to a standard home internet connection. This makes the technology ideal for quickly syncing contacts, photos, and even streaming video to a TV.
It is important to note that the connection is secure, as it requires confirmation on both ends. The encryption protocol WPA2 guarantees that your data will not be intercepted by third parties within the signal range.
⚠️ Please note: When actively using Wi-Fi Direct, your regular Wi-Fi module may temporarily disconnect from the internet as your smartphone's antenna switches to direct transmission mode. Don't be surprised if your network connection is lost while copying files.
Finding the function in MIUI and HyperOS settings
Smartphone owners Xiaomi, Redmi And Poco Users often have difficulty finding this option. This is because in modern shell versions, developers have removed the separate enable button from the quick menu. The function is now deeply integrated into the system and is activated automatically when selecting a transfer method.
To access connection management, you'll need to go to advanced network settings. The path may vary slightly depending on the version. Android, but the general logic remains the same for all devices of the brand.
Follow the algorithm:
- 📱 Open the Settings app from your home screen.
- 📡 Go to the "Connection and Sharing" or "Wi-Fi" section.
- ⚙️ Find the "Wi-Fi Direct" item at the bottom of the menu or in the additional list.
- 🔍 Activate the switch if it is available for manual control.
In some cases, especially on older versions MIUI, there may not be a separate menu at all. The system automatically launches the module when you select the appropriate transfer method in the gallery or file manager.
Instructions for connecting between devices
The process of pairing two devices Xiaomi or smartphone Xiaomi with another gadget (for example, a TV LG or Samsung) is quite simple, but requires attention. The main requirement is that the wireless module must be enabled on both devices.
First, make sure the screens of both devices are unlocked. The security system may block connection requests from unknown devices if the phone is in sleep mode.
☑️ Checklist before connecting
The steps to initiate a connection are:
- On the sending device, open the file you want to transfer.
- Click the Share button and select Wi-Fi Direct or "Mi Drop" (now Xiaomi Share).
- The sender's name should appear in the list of available networks or devices on the receiving device.
- Accept the connection request, verifying the security codes if displayed.
After a successful handshake, the devices exchange encryption keys and data transfer begins. Speeds at this point can reach 20-30 MB/s or more, significantly faster than Bluetooth.
Using Mi Share and Xiaomi Share
Company Xiaomi implemented its own add-on to the standard protocol, which was called Mi Drop, and was later renamed to Xiaomi ShareThis is a more convenient alternative to Apple's AirDrop, running on Android.
This feature combines Bluetooth's ability to search for devices and Wi-Fi Direct for file transfers. You don't need to manually search for networks and enter passwords. Simply enable the feature in the notification shade.
| Function | Bluetooth | Wi-Fi Direct | Xiaomi Share |
|---|---|---|---|
| Speed | Low (up to 2 Mbps) | High (up to 250 Mbps) | High (automatic) |
| Range | ~10 meters | ~100 meters (in theory) | ~20 meters |
| Energy consumption | Minimum | High | Average |
| Convenience | Requires pairing | Requires configuration | Automatically |
Usage Xiaomi Share This is preferable if you're transferring files between devices of the same brand. However, for compatibility with other Android smartphones, it's better to use a standard protocol or app. Quick Share from Google.
The Secret of High Speed
The protocol uses 5 GHz frequencies if both devices support this range. This allows for maximum throughput, which is unavailable with Bluetooth.
Transfer files to TV and PC
One of the most popular use cases for this technology is displaying images on a large screen. Most modern Smart TVs support the standard. Miracast, which is based on Wi-Fi Direct.
To broadcast a picture from a smartphone Xiaomi on the TV, follow these steps:
- 📺 Make sure your TV and phone are on the same network (or just turn on Wi-Fi on both).
- 📲 On your phone, open Control Center (swipe down from the upper right corner).
- 🖥️ Select "Broadcast" or "Cast".
- 📡 Find your TV in the list and click on it to connect.
If you want to transfer files to your computer, you'll need third-party software, as Windows doesn't have built-in support for receiving files over pure Wi-Fi Direct without additional drivers. You can use programs like Feem or Snapdrop, which create a local network.
⚠️ Note: Smart TV interfaces from different manufacturers (Samsung, LG, Sony) may refer to this feature differently: Screen Share, Smart View, or Mirroring. Look for the section on connecting mobile devices.
Troubleshooting connection issues and errors
Despite its convenience, the technology is not without its drawbacks. Users occasionally encounter problems with devices not seeing each other or with the connection constantly dropping. Most often, the problem stems from power saving settings.
System MIUI is known for its aggressive battery optimization. It can "kill" the background device search process, considering it a waste of power. To prevent this, you need to grant the appropriate permissions.
Typical causes of failures:
- GPS (geolocation) is disabled. On Android, without GPS enabled, searching for Wi-Fi Direct devices is disabled.
- Flight mode is activated or Bluetooth is turned off (needed for the initial handshake).
- Outdated Wi-Fi module drivers.
It's also worth checking that "Stealth Mode" isn't enabled in your Bluetooth and Wi-Fi settings. If the device is hidden, it won't appear in the list of available devices.
Security and hidden features
Using a direct connection, you create a channel that bypasses your router. This means your internet service provider (ISP) can't see the traffic transmitted between devices. However, the Wi-Fi Direct network itself must be password-protected.
When connecting for the first time, always verify the pairing request. Attackers in crowded public places may try to create a network with a name similar to your device to initiate a connection.
Hidden feature: Some users use Wi-Fi Direct to create local chats or transfer files in situations where the internet is completely unavailable (for example, on the subway or during infrastructure damage). There are dedicated messaging apps that work exclusively with this protocol.
⚠️ Warning: Do not accept files from unknown devices via Wi-Fi Direct. While the risk of infection is minimal without download confirmation, attackers can exploit protocol vulnerabilities to scan your device.
Conclusion and recommendations for use
Technology Wi-Fi Direct on smartphones Xiaomi remains a powerful tool for fast data transfer. Despite the development of cloud storage and messaging apps, a direct connection is often the only way to quickly transfer gigabytes of video or a system backup.
Please note that the settings interface may change with updates. HyperOSIf you don't find the options described above, use the settings search by typing "Direct" or "Broadcast."
Use this feature when working with large amounts of data to avoid wasting mobile data and save time. Proper setup will allow you to forget about wires and slow Bluetooth.
☑️ Final check
Why doesn't Wi-Fi Direct work without GPS enabled?
In modern versions of Android (starting with 6.0), access to Wi-Fi network scanning, including Direct, is tied to the location permission. This is done to protect privacy, as the MAC addresses of access points can be used to determine the user's location.
Can I play games via Wi-Fi Direct on Xiaomi?
Yes, many games support local multiplayer via Wi-Fi Direct. This allows you to play with friends without internet access, creating a local network between phones. Latency (ping) on this connection is minimal.
Does Wi-Fi Direct drain my battery faster than regular Wi-Fi?
Yes, power consumption is higher in active data transfer mode, as the module operates at full power to ensure a stable connection. However, in standby mode, searching for devices consumes no more power than standard Wi-Fi.
How to disable automatic device search?
To stop the search, simply turn off the Wi-Fi switch in the notification shade or disable the "Visibility" feature in the connection settings. Enabling "Airplane Mode" also helps.
