One such feature is wireless data transfer technology, which allows you to share files between devices without using a router or mobile data. This solution is ideal for quickly transferring photos, videos, or documents when traditional Wi-Fi is unavailable.
Many device owners Mi And Redmi Many people confuse this feature with a regular access point or Bluetooth, failing to understand the true potential of a direct connection. Unlike Bluetooth, its transfer speed is significantly higher, and its range allows for comfortable operation over several meters. Understanding how this protocol works will help you manage your multimedia and peripherals more effectively.
In this article, we'll detail the steps for activating direct connection mode, explore the nuances of working with printers and TVs, and analyze common errors. You'll learn how to properly configure device visibility and what security settings to consider when working in public spaces.
What is Wi-Fi Direct and why is it needed on a smartphone?
Technology Wi-Fi Direct is a wireless communication standard that allows two devices to connect directly to each other, bypassing the need for an access point or router. In the ecosystem Android, including the shell MIUI And HyperOSThis protocol is often used as a base layer for various data transfer functions. The main difference from a classic connection is that one of the devices assumes the role of a control node.
This mode is useful when you need to transfer a large file but don't have a cable or stable internet connection. Data transfer speeds over this channel can reach levels comparable to regular home Wi-Fi, making the process of copying movies or photo archives virtually instantaneous. Furthermore, the protocol supports encryption. WPA2, which provides a basic level of protection for transmitted information.
It is important to understand that on smartphones Xiaomi This feature is often hidden deep within system settings or integrated into other services such as Mi Share or Google Nearby ShareThe user doesn't always need to manually enable discoverability mode, as many applications do this automatically when starting a transfer. However, for connecting specific peripherals, such as older printers or projectors, manual activation may be necessary.
Power consumption when using direct connection mode is higher than when using Bluetooth, but significantly lower than when using a mobile hotspot. This allows for large amounts of data transfer without critically draining the battery. For those who frequently work with multimedia, understanding the operating principles P2P Peer-to-Peer networking is an important skill for optimizing smartphone performance.
Preparing your Xiaomi device for direct connection
Before attempting to establish a connection with an external device, you must ensure that your smartphone is Xiaomi Properly configured and ready to use. First, check that the wireless module is activated. Even if you're not connected to a specific network, the module itself should be enabled, as it's responsible for scanning the surrounding area and finding available nodes.
The next step is to check your device's name. In its default form, it often looks like the phone model, for example, Redmi Note 10 or Mi 11For easier identification in the list of available devices on the receiving end, it's best to give it a descriptive name. You can do this by going to the menu Settings → About phone → Device nameThis is especially important if you are in a crowded area where the airwaves are saturated with signals from other gadgets.
⚠️ Attention: Make sure location services are enabled on both devices. In modern versions of Android, this is a requirement for nearby device discovery protocols to work; without it, the list of devices available for connection may remain empty.
It's also worth paying attention to the operating system version. Developers Xiaomi regularly update the software, and in new versions MIUI Some menu items may have been moved or renamed. If you don't see the options you need, check for system updates in the Settings → About phone → MIUI versionUp-to-date software ensures compatibility with the latest security standards and communication protocols.
Don't forget to check the battery charge. Although the technology is energy-efficient, active searching and data transfer can quickly drain the battery. It's recommended to have at least 20-30% charge before working with large files. If you plan to transfer 4K video, it's best to connect the device to a power source to avoid unexpected shutdowns mid-stream.
Step-by-step instructions: how to activate visibility mode
Unlike some other manufacturers, the interface Xiaomi There's no single "Enable Wi-Fi Direct" button. Activation occurs either automatically when supporting apps are launched, through a hidden engineering menu, or through the peripheral connection settings. Let's look at the main activation method, which is through the standard system settings and works on most current models.
To begin, open your smartphone's main settings and find the section responsible for connections. Depending on your firmware version, it may be called "Connection and Sharing" or simply "Wi-Fi." We need to go to the advanced settings. Often, the desired option is hidden in the additional features menu or in the wireless module settings section. Click the gear icon or arrow next to the name of the active network.
☑️ Check before connection
Next, you need to find the item responsible for direct connections. In some builds MIUI In some models, it's a separate feature, while in others, it's integrated into the "Access Point" menu. If you're looking for a way to make your phone discoverable to a printer, it's often enough to simply turn on Wi-Fi and launch the printing app, which will automatically initiate discovery mode. To manually enable it in the engineering menu (not available on all models), the path might look like this: Settings → Advanced settings → For developers, where you need to look for options related to P2P.
Once the appropriate settings are enabled, the phone will begin broadcasting a signal indicating it's ready to connect. A notification may appear on the screen indicating the device is discoverable. At this point, the receiving device (e.g., a TV or another phone) should begin searching for new devices. The search process typically takes 5 to 15 seconds.
When trying to connect on the smartphone screen Xiaomi A system window will appear asking for confirmation. It will display the name of the requesting device and the type of action requested. Click "Accept" or "Connect." Sometimes the system may prompt you to enter a PIN, which is often specified by default in the receiving device's manual or generated automatically.
Using the feature to transfer files and media
One of the most popular use cases for the technology is file transfer between smartphones. This doesn't require third-party apps if both devices support the standard. Mi Share, which is based on direct connection protocols. However, if you're transferring a file to a device of a different brand or older model, the procedure will be slightly different.
To transfer a file, open your gallery or file manager, select the desired item, and tap the "Share" button. From the list of available methods, select the direct connection option (often indicated by a Wi-Fi icon or two arrows). Your phone will automatically enter search mode. Once the target device is found, the pairing process will begin. Transfer speeds in this mode can reach 20-40 MB/s, which is significantly faster than Bluetooth.
| Parameter | Bluetooth | Wi-Fi Direct | USB cable |
|---|---|---|---|
| Transfer speed | up to 3 MB/s | up to 250 MB/s | up to 480 MB/s |
| Range | up to 10 meters | up to 200 meters | up to 2 meters |
| Energy consumption | Low | Average | Charging the device |
| The need for couples | Required | Not required | Not required |
When transferring videos or large archives, it is important not to interrupt the connection or switch between applications. Although the system Android It can save progress even if the connection is interrupted. In direct connection mode, a disconnection may require restarting the transfer. It's also worth considering that during active file transfers over this channel, the smartphone's internet connection may temporarily disconnect or become unstable, as the module is busy with direct data exchange.
Why is the file not being transferred?
If the transfer stops mid-stream, check if the receiving device is in power saving mode. It may be blocking background data recording. Also, make sure there's enough free disk space.
Connecting peripherals: printers, televisions, and projectors
Smartphones Xiaomi They work great as a remote control or signal source for various peripherals. Connecting a wireless printer is one of the most popular features in the office and at home. Most modern printers HP, Canon And Epson Support direct mode. To connect, go to the printing settings on your phone (usually located under "Connection and Sharing" → "Print") and add the device using the search.
When used with TVs and projectors, the technology allows you to stream screen images or specific video files without the lag that is typical with Chromecast when the internet connection is poor. If your TV supports Miracast or similar standards, telephone Xiaomi You can find it in the "Broadcast" or "Cast" menu. In this case, the phone creates a video stream that is directly decoded by the TV.
Connecting to a projector is similar to connecting to a TV. Make sure the projector is in Wi-Fi standby mode. On your phone, select the device from the list of available devices. If a PIN is required, it can be found in the projector's settings menu. Image quality with this connection is typically higher than with Bluetooth, and it supports Full HD resolution.
⚠️ Attention: When connecting to corporate printers or projectors in offices, ensure you don't create IP address conflicts. On some networks, direct device connections may be blocked by IT security policies.
It is important to note that some older models of peripherals may require the installation of additional plugins. Xiaomi service is often used for this purpose Default Print Service or specialized apps from the equipment manufacturer that automatically detect an active direct connection. If the automatic search doesn't yield results, try downloading the printer manufacturer's app from Google Play.
Security Configuration and Troubleshooting
Security is a critical aspect when using direct connections, especially in public places. By default Xiaomi Uses encryption, but your device name may be visible to everyone. It's recommended to change your phone name to a neutral one that doesn't contain personal information if you frequently use this feature in cafes or on public transport. Also, avoid accepting files from unknown senders, even if the system displays a file preview.
One common issue is when devices don't see each other. In 90% of cases, this can be resolved by rebooting the Wi-Fi module on both devices. Turn Wi-Fi off and on, wait 10 seconds, and then try searching again. Clearing the Wi-Fi Direct cache can also help: go to "Applications" → "Show system processes" → "Wi-Fi Direct" → "Clear cache."
If the connection is established but immediately disconnects, check your power saving settings. System MIUI is known for its aggressive optimization, which can "kill" background data transfer processes. Add the app that is transferring data or the system Wi-Fi service to the battery exception list. To do this, go to Security → Battery → Settings and select the "Unlimited" mode for the required components.
Another common error is frequency mismatch. Some older devices only operate at 2.4 GHz, while modern ones Xiaomi They may attempt to initiate a connection on 5 GHz. In the Wi-Fi settings (under Advanced Settings), you can try forcing a band switch or disabling "Smart Network Selection" to stabilize the connection with legacy devices.
Frequently Asked Questions (FAQ)
Does Wi-Fi Direct affect internet speed?
Yes, it can. Since a single radio module is used, when actively exchanging files via a Direct connection, internet traffic may become unstable or temporarily interrupted, as the channel is busy transferring data between devices.
Is it possible to connect Xiaomi to iPhone via Wi-Fi Direct?
A direct native connection using the Wi-Fi Direct standard between Android and iOS is often impossible due to differences in Apple's protocol implementations. However, if both devices use intermediary apps (such as Send Anywhere or Xender), they create their own local network over this protocol, allowing file transfers.
Where can I find the history of transferred files?
The history depends on the app used for the transfer. If system sharing was used, files are usually saved in a folder File Manager → Wi-Fi or Internal Storage → MIUI → bluetooth (Sometimes files from Direct are saved there too.) In file explorers, look for folders with the name of the sent file or the date.
Why is the connection so slow?
Slow speeds can be caused by interference in the air, long distances between devices, or the use of the outdated 802.11b/g standard. Speeds can also drop if one device has a weak signal or is overloaded with background tasks.
