Xiaomi smartphone owners often face the need to transfer large files quickly when standard methods are too slow or require Internet access. WiFi Direct technology allows you to create a direct connection between devices without using a router, providing high data exchange speeds. This is especially true for users who regularly share 4K videos, heavy archives or sets of high-resolution photos.
Many people confuse this feature with the usual mode of the access point or Bluetooth, but the transmission protocol here is fundamentally different, using the capabilities of the wireless module at maximum frequency. In the MIUI and HyperOS ecosystem, the implementation of this standard has its own features, hidden in the depth of system settings or brought to individual utilities. Understanding the principles of this interface will help you significantly speed up everyday tasks and save traffic.
In this article, we will take a closer look at the nuances of activation and use of the technology on Chinese brand devices. You will learn where to look for hidden switches, how to correct gadgets and what to do if the connection is broken. On new versions of MIUI shells, the standard WiFi Direct interface is often hidden, and it requires the use of third-party applications or an engineering menu to activate it.
What is WiFi Direct and why you need it on your smartphone
WiFi Direct technology is a standard that allows two devices to connect directly to each other without needing an access point or router. Unlike classic Wi-Fi, where all devices connect to a single central node, here the smartphone itself becomes a network node, which provides a stable connection with high bandwidth, which is critical for streaming media files without delay.
The main advantage of using this protocol on Xiaomi is that it can transfer data speeds up to 250 Mbps or higher, which is ten times faster than Bluetooth. In addition, the connection is established almost instantly after a request is confirmed, and users often use this method to display images on Miracast-enabled TVs or to print documents on network printers without a cable connection.
It's important to understand the difference between a regular Wi-Fi and a direct connection: in the first case, the Internet is distributed via a router, and in the second case, a local network is created between two specific gadgets, which means that there is no Internet connection at all to transfer photos from phone to phone, which saves battery power and frees up the radio channel.
- 🚀 High speed transfer of large files without compression of quality.
- 🔒 Secure connection using encryption WPA2.
- 📱 Possibility of connecting peripherals: printers, cameras, TVs.
- 🌐 Work without the need for an active Wi-Fi hotspot.
⚠️ Note: With an active WiFi Direct connection, battery consumption can increase significantly, as the wireless module is in high power mode. Do not leave the file transfer process uncontrolled if the device charge is below 20%.
Where to find the function in the settings MIUI and HyperOS
Finding WiFi Direct feature in Xiaomi smartphones can be a real puzzle, as in the latest versions of the MIUI and HyperOS shells, manufacturers removed direct access to this menu from the standard settings. Previously, the switch was in the “Additional Settings” section or in the Wi-Fi menu, but now it is often hidden. This is done to simplify the interface, since most users use alternative transfer methods such as Mi Share or Google Nearby Share.
Access to hidden features sometimes requires the use of special codes in the engineering menu or the installation of third-party activator applications. However, before resorting to complex methods, it is worth checking the standard paths. Go to Settings → Connection and Sharing and carefully study all subsections. In some regional firmware (Global ROM), the function can be renamed or integrated into the print menu.
If you can't find the switch in the standard way, you can search by settings, type "WiFi Direct" or "Direct Connection" into the search box, and the system can offer a shortcut that will take you to the right screen, even if the button is not in the main menu. Otherwise, you will have to use ADB-team or third-party software.
How to activate through the Engineering Menu
Step-by-step instructions for connecting devices
The process of pairing devices via WiFi Direct on Xiaomi requires several steps to be performed in sequence. First, make sure that the wireless module is activated on both gadgets. Then on the sender device, a file or application is selected that will use a direct connection. The receiver should be in visibility.
Consider the algorithm for a successful connection. If you use a third-party application to activate the function, the interface may be different, but the logic remains the same. The initiator device scans the space, finds the target gadget, and sends a pairing request. A notification will appear on the screen of the receiving device asking you to confirm the connection.
Once confirmed, a secure communication channel is established, at which point it may be necessary to enter PIN-Make sure the codes match to avoid connecting to someone else's device in a public place. After a successful handshake, the status bar will have a corresponding icon.

| Support for files | Anybody. | Anybody. | Limited OS |
Use of third-party applications for activation
Because Xiaomi restricts direct access to WiFi Direct in stock settings, many users resort to the help of specialized software from Google Play. Applications like "WiFi Direct File Transfer" or "SuperBeam" have their own interfaces to control the wireless module, bypassing the system limitations of the MIUI shell. They force the desired mode of operation of the chip.
When installing such programs, the system may request advanced permissions to access the network and location, which is necessary for proper scanning of the environment and management of connections. After installing the application, it is usually enough to click the "Enable" or "Start Server" button to start the process of searching for devices. The interface of such programs is often more informative than the standard Android menu.
It is worth noting that the use of third-party software can lead to conflicts with the system services Mi Share. If you plan to constantly use a direct connection, it is recommended to disable native sharing functions or choose one main application.
💡
Before installing third-party WiFi Direct activators, back up important data. While the risk is minimal, interfering with network modules through third-party code always poses a potential threat to system stability.
Solving common problems and errors
Despite the convenience of the technology, users often have difficulty connecting. One of the most common problems is that devices can’t see each other. In this case, you need to check whether one of the smartphones is in flight or energy saving mode, which limits the background activity of the radio module. Also make sure that both devices are in the same frequency band (2.4 GHz or 5 GHz), although WiFi Direct usually controls this setting.
Another common mistake is to break the connection immediately after the transfer starts, which can be caused by overheating of the smartphone or aggressive battery optimization in HyperOS. The system can force the background transfer process to close, considering it to be energy-consuming. To avoid this, add the transfer application to the optimisation exception list: go to Settings → Battery → Energy Saving and select No Limits mode for the desired application.
If the connection is established, but the speed is extremely slow, try to turn off the mobile Internet on the receiving device. SIM-The map creates direct channel conflicts, and rebooting network settings through the Connect and Sharing menu also helps. → Reset Wi-Fi, mobile networks and Bluetooth.
⚠️ Note: If you try to connect, you see a message "Can't get it" IP-"address" indicates an addressing conflict. Try forgetting the network on both devices and rebooting them before you try to pair them again.
Security and data protection in the transmission
WiFi Direct uses a local network that depends on encryption settings to secure its security. The protocol uses WPA2 to protect data transmitted from being intercepted by outsiders nearby. However, unlike password-protected Wi-Fi networks, direct connections often require manual on-screen confirmation, a major barrier for hackers.
However, it is not recommended to use a direct connection in crowded places, such as airports or shopping malls, unless absolutely necessary. Attackers can use protocol implementation vulnerabilities on specific Xiaomi models to attempt unauthorized access. Always check the name of the device you are connecting with, especially if it has a standard name like "Android Device".
For maximum security, avoid transmitting sensitive data such as passwords or bank details through open direct transmission protocols unless there is a pressing need. Always break the connection manually after the transfer session is over. Leaving the module in active visibility increases the risk of Man-in-the-Middle attacks.
💡
WiFi Direct security is provided by WPA2 encryption and mandatory pairing confirmation on both devices, making data interception difficult but requiring the user to be careful when choosing a target device.
