What is WiFi Direct and why is it needed on the Redmi Note 7?
WiFi Direct — is a wireless communication standard that allows devices to connect to each other directly, without the need for an access point or router. Unlike classic Wi-Fi, where all devices depend on a central base, here is a smartphone Redmi Note 7 can act as a server or client, creating a secure peer-to-peer connection. This provides significantly higher data transfer speeds compared to Bluetooth and allows you to stream high-definition video without delays.
Using this technology on Xiaomi opens up a number of useful use cases that aren't available with a standard connection. For example, you can mirror your smartphone's screen to a supported TV. Miracast, print documents on network printers, or quickly transfer gigabytes of photos between phones. The protocol uses the same frequencies as regular Wi-Fi, but operates on a one-to-one or one-to-many basis.
⚠️ Please note: When actively using WiFi Direct, the wireless module operates in enhanced mode, which may result in increased battery consumption. We recommend monitoring the battery level during extended sessions transferring large files.
It's important to understand the difference between this technology and a regular hotspot. If an access point creates a local network with internet access (if mobile data is available), then direct connection intended solely for local data exchange between specific devices. Redmi Note 7 This functionality is especially relevant for ecosystem owners MI Home or those who often work with office equipment.
Technical characteristics of the module

Configuration via the engineering menu and hidden options
For advanced users who require full control over their network adapter, there is the option to access advanced settings. Redmi Note 7 You can enable the display of additional parameters through the engineering menu or special commands. This allows you to check the module's status, view the MAC address in Direct mode, and force a scan.
One way to access the testing menu is to use a code in the Phone app. Enter the code ##6484## to enter CIT (Customer Interface Test) mode. Here you can check the functionality of the wireless modules, but direct connection Direct This may not be available depending on the firmware version. A more effective method is to use ADB commands if USB debugging is enabled on the phone.
If you plan to use your smartphone for debugging or specific network tasks, you may need to enter a command to enable WFD (Wi-Fi Display) mode. This is entered via a computer with ADB:
adb shell wm sizeHowever, for most users, it's enough to know that the hidden switch is activated contextually. In new versions MIUI You can now add a "Security" or "Wi-Fi" widget to your desktop, which sometimes displays the status of P2P (Peer-to-Peer) connections. Please note that tampering with system settings may affect network stability.
Using third-party applications to manage the connection
If standard means Xiaomi If you find that apps from the store aren't informative enough or aren't working correctly, you can use apps from the store. Google PlayThere are many utilities that can force the inclusion WiFi Direct and provide a convenient interface for file management. Such programs often have more flexible device visibility settings.
One of the most popular solutions is the application WiFi Direct from the developer Medha Apps or similar things like SuperBeamAfter installing such software on Redmi Note 7, you get a direct button to enable the mode. The app takes control of the network interface, creating a group or joining it at your command.
