How to disable Wi-Fi Direct?

To enable Wi-Fi Direct, go to “Settings”. “Connections”. “Wi-Fi”, then click on the Wi-Fi Direct tab at the top. Your smartphone will start searching for devices that you can connect to.

Wi-Fi Direct is a connection that allows you to exchange data between devices, connecting the devices together without the presence of a nearby centralized network. One device acts as an access point, and another device is connected to it using Wi-Fi Protected Setup (WPS) and Wi-Fi Protected Access (WPA / WPA2) security protocols.

Initial answer: What is the difference between Wi-Fi and Wi-Fi Direct? Wi-Fi is usually used to connect to a network and / or Internet. Wi-Fi Direct is used specifically to connect the device to the device bypassing the network.

What is Wi-Fi Direct for

Wi-Fi Direct can be used to connect any devices that support this technology and need to exchange information. For example, Wi-Fi Direct can be used for:

  • Connections of two phones;
  • Printer connection;
  • Keyboard or mouse connection;
  • TV or projector connection;
  • Connections of a camera or video camera;

How to enable Wi-Fi Direct on the phone

In order to enable Wi-Fi Direct on the phone with the Android 8 operating system.1 You need to open the settings, go to the section “Network and Internet-Wi-Fi”, include ordinary Wi-Fi there and go to the “Wi-Fi Settings” subsection.

Next, you need to open “extended settings”.

As a result, the search for other devices with support for Wi-Fi Direct will begin.

After the right device is found, you need to click on it and confirm the connection via Wi-Fi Direct. After that, it will be possible to exchange data between the devices. For example, in order to send the file you need to click on the “Share” button and select “Wi-Fi Direct” in the menu that opens.

How to use Wi-Fi Direct on the phone with Android?

Typically, Wi-Fi Direct technology does not need to install additional software on the phone. The Android system already contains appropriate settings. I already showed how the “wireless display” works in Xiaomi. Now let’s look at the example of the “naked” Android 8.0:

    Turn on Wi-Fi on a mobile device (“Settings”-“Network and Internet”)

After establishing the connection, the user will be able to transmit information, broadcast the image from the screen or play sound files on the television columns.

Applications for Wi-Fi Direct on Android

Despite the fact that support for the Wi-Fi Direct function is already built into all modern operating systems, there are many applications from third-party developers. They often simplify the work and make control of the screen display more friendly to beginners.

    Cast to TV. The application is intended for convenient information transmission through the Wi-Fi Direct protocol. The program has a simple integration, which any users can figure out. The main features are video broadcasting on a home TV, automatic search for available devices, built.in file identification. Also, the undoubted advantage of Cast to TV is the control of the TV through the sensory intese. The user is able to adjust the sound level from his smartphone, pause to pause or rewind the video to the necessary position.

The main disadvantages

Before you understand how Wi-Fi Direct works, you should briefly run in comparison with two technologies that often confuse.

  • Higher data transfer speed. up to 250 Mbps.;
  • Extended radius of the technology. up to 200 meters;
  • The possibility of connecting not two devices. but sets;
  • Enhanced degree of security of the Wi-Fi connection;
  • Only one device can be equipped with a special chip, this is enough.

What is Wi-Fi Direct technology on the phone We figured out-let’s talk about how to enable the option and use to connect devices.

Peculiarities

This connection method has numerous advantages:

Safe direct connection between devices, installed similarly to Bluetooth, that is, you just need to select a suitable element from the list, without thinking about PSK and SSID;

The speed of such networks is much faster than the traditional Bluetooth;

A significantly larger distance between the devices is allowed;

A high degree of reliability and safety is guaranteed by constantly working WPA2, which cannot be disabled.

Wi-Fi Direct is not necessarily a one-on-one connection

The fact that Wi-Fi Direct will most often be used to connect two devices among themselves does not yet mean that the capabilities of the standard will be limited. Within the framework of the new technology, it will be possible to create entire groups of interconnected devices (Wi-Fi Direct Group).

Most often, such group configurations, apparently, will be used for multiplayer games. Players in this case do not need access to the Internet, mobile or any other coating. Being literally in the desert, they will be able to create a small wireless network if their devices are in the reach of each other.

over, not all network participants must support Wi-Fi Direct. One Wi-Fi Direct chip is enough, which will take on the role of the traffic coordinator between devices with ordinary Wi-Fi modules on board.

It should be noted that in some cases the creation of groups will be impossible, since some devices are originally created only for connections such as “one on one”. This does not contradict the specifications of the standard in which the ability to connect to several devices is an optional.

How many devices can be combined into a group or connected to one device depends on specific conditions. As a rule, this number will be slightly lower than in the case of a regular access point

It is worth adding that despite the kinship of Wi-Fi and Wi-Fi Direct, these are still slightly different technologies, which is once again confirmed by the following fact. Certified devices (from the context of the impression that the majority) will be able to connect either to Wi-Fi Direct to groups, or to ordinary Wi-Fi access points, and only some of them will be able to do both at the same time. For example, a laptop can be connected via a router to the Internet and at the same time enter a group to Wi-Fi Direct, to distribute this Internet to other group members.

Wi-Fi Direct: Au Revoir Bluetooth

Will Wi-Fi Direct be completely replaced by Bluetooth, it is difficult to say with 100% confidence now, but all the prerequisites for this are. In the new Wi-Fi derivative both with the transfer speed and the coating radius, and with data security and ease of connection, things are much better than Bluetooth.

Getting rid of excess wireless integration in mobile devices will be on the hands of both manufacturers and users: the devices will become a little more compact, easier, cheaper, and easier in production, and users instead of two intenses will have to only be monitored by switching one.

The new technology can be built into almost any devices, including those that traditionally work on Bluetooth (wireless keyboards, mice, headsets). To increase autonomy specifically for Wi-Fi Direct, new energy conservation modes were also developed.

How to display a phone screen onto the TV

Wi-Fi Direct can be supported not only by smartphones, but also by TVs. For example, my Samsung TV supports this technology, allowing you to install a mating with a phone. Thanks to Wi-Fi Direct, I can display the desktop of my device to the large screen, send a video or photo from it or even turn on the desktop mode. This is an exclusive feature of Huawei and Honor smartphones, so I’m not sure that you also have it. But try:

Wi-Fi Direct can be turned on on almost any smartphone

But the desktop mode is not on many smartphones

Honestly, I have never used this mode before, but I really liked it. In this mode, the TV displays a full.fledged desktop intense as on a computer with all icons and a lower dock with relevant information and current tasks performed on the device. And if you install a smartphone next to the TV, you can conduct video conferences on the big screen.

How to transfer a file via wi-fi direct

However, Wi-Fi Direct can also be used to quickly transfer data. As for me, it is even better than an incomprehensible Nearby Sharing. In contrast, Wi-Fi Direct works at long distances, and the data transfer rate of both technologies is comparable. True, some devices for some reason do not allow transmitting data without special applications. Therefore, I use “Wi-Fi files” for these purposes for these purposes.

On Wi-Fi Direct, data are transmitted very quickly

Of course, to transmit data on “Wi-Fi file transfer”, it is necessary that both users have this application on their devices. It acts as a link, although the actual transmission is carried out on a wireless Wi-Fi channel. The “Wi-Fi file transfer” application is quite simple, it has all the necessary elements-it allows you to immediately select the necessary files for transmission, find the receiver device and quickly send everything or accept everything.

What is Wi-Fi Direct

Wi-Fi Direct is a connection that allows you to exchange data between devices, connecting them among themselves without connecting to the nearest centralized network. One device acts as an access point, and another device is connected to it using Wi-Fi Protected Setup (WPS) and Wi-Fi Protected Access (WPA / WPA2) security protocols. The standard was developed and introduced into devices in the early 2000s.

It may seem that all this is very similar to Bluetooth, and at first glance, technology may really seem like similar, but there are several important differences between them. One of the most important is that Wi-Fi Direct can process more information at higher speeds than Bluetooth. The difference is about tenfold under the same conditions. This increase makes Wi-Fi Direct an excellent choice when you need to transfer content with a large volume of data, for example, an image with high resolution or video. And even when the Wi-Fi network does not work.

Through Wi-Fi Direct it is fashionable to transfer files from one device to another.

What is Wi-Fi Direct

One of the most significant advantages of Wi-Fi Direct is its versatility where there is no single Wi-Fi network. Several devices can contact each other and exchange important files without unnecessary intermediaries and unnecessary difficulties.

Often you can determine when the device offers Wi-Fi Direct, because when searching it pops up with its own wireless network, usually starting with the word “Direct”, followed by the name or number of the product.

What is Wi-Fi Direct and how to use it on a smartphone running Android

The list of functions of our Android smartphones is quite extensive, and some of them can easily go unnoticed. Meanwhile, they can be very, very useful. For example, on almost every smartphone there is a Wi-Fi Direct function. A couple of years ago she made a lot of noise, but today most people do not even know about her. And in vain, because this is a very useful feature of your smartphone.

First, let’s figure out what it is. Wi-Fi Direct is a certificate of association called Wi-Fi Alliance, which includes more than 600 members such as Apple, LG, Intel, Microsoft, Google, Dell and so on. Devices with Wi-Fi Direct are compatible with each other regardless of the manufacturer. First of all, these are tablets, smartphones, laptops and digital chambers. Starting with Android 4.0 ICE Cream Sandwich all Android Smartphones have this function “out of the box”.

Thanks to Wi-Fi Direct, you can create a wireless network between several devices. In addition, you can use Wi-Fi Direct in combination with, for example, Miracast to broadcast images to another device. The latest generation Wi-Fi Direct is also compatible with NFC.

In the case of Android Smartphones and tablets, you can combine gadgets into one network and quickly transfer files between them. The advantage of using Wi-Fi Direct over Bluetooth is that the Wi-Fi frequency range and the transmission rate is much higher than that of Bluetooth.

How to configure Wi-Fi Direct

Each Android Smartpho that uses Android 4.0 and above, has a Wi-Fi Direct function (with some very rare exceptions). Although the user integrations of systems may vary, setting this function is relatively simple and unified on all devices. Wi-Fi Direct does not support the transfer of files at the moment, so you will need to install a third-party application. For example, Send Anywhere.

Unlike Bluetooth, there is no special button in the fast menu for working. Wi-Fi Direct always works when you have a stable Internet connection. But this does not mean that Wi-Fi Direct is included all the time. To enable Wi-Fi Direct, follow the “Settings”-“Connection”-“Wi-Fi”-“Wi-Fi Direct”.

Important: you also need to turn on Wi-Fi Direct on all your devices, otherwise it will not work to combine them into one wireless network.

If TV is not Smart

If you are the owner of the old TV or it does not have an Internet access, then you still do not have to use wires to broadcast content. By buying Smart Box with Android, you can make from your usual panel. Smart. Such prefixes have a built-in Wi-Fi module with support for Mirakast and Wi Dai Technologies. The setting in this case is no different. the prefix is ​​connected through HDMI, on TV we turn on the signal source selected, and then everything is analogy with the usual Smart TV.

Thank you for your attention! And until new meetings on the blog! Sincerely, Kuzmin.

In conclusion

The installation of a wireless technology connection is not very different from the connection, for example, a smartphone and a headset. Its implementation will require the presence of a Wi-Fi Direct function on TV. If there is no, you can use USB adapter.

To be honest very disappointed in this technology, with very great potential it works poorly. It is not clear what the problem is, or in the data transfer protocols and software, felts in the modules. Connection does not occur to all devices, so people still use the good old Bluetooth.

Perhaps the problem lies in the variety of versions of the Android OS. The fact is that some operating systems are made exclusively for a particular phone. The difference in the software product can affect data transfer standards.

According to Weca, which invented this technology, it will soon be repaired, and on new devices it will work as a clock.
