Its onConnectionInfoAvailable callback notifies you when the state of the connection changes. In cases where multiple devices are going to be connected to a single device like a game with three or more players, or a chat app , one device is designated the "group owner".
You can designate a particular device as the network's group owner by following the steps in the Create a Group section. When this intent is received, call requestConnectionInfo.
This is an asynchronous call, so results are received by the connection info listener you provide as a parameter. Kotlin when intent.
Create a group If you want the device running your app to serve as the group owner for a network that includes legacy devices—that is, devices that don't support Wi-Fi Direct—you follow the same sequence of steps as in the Connect to a Peer section, except you create a new WifiP2pManager. ActionListener using createGroup instead of connect. The callback handling within the WifiP2pManager. ActionListener is the same, as shown in the following code snippet:. Note: If all the devices in a network support Wi-Fi Direct, you can use the connect method on each device because the method then creates the group and selects a group owner automatically.
After you create a group, you can call requestGroupInfo to retrieve details about the peers on the network, including device names and connection statuses. Content and code samples on this page are subject to the licenses described in the Content License.

This feature can make the process much faster, especially if it has to add a lot of new media at the same time think about updating old music playlists, for example. However, the IoT has become dominated by Wi-Fi networks, with older connection technologies like Zigbee and, yes, Wi-Fi Direct being quickly left behind.
We should talk a bit about that. Wi-Fi Direct has minimal security advantages compared to other options, but it has minimal security risks. It can be risky while simultaneously using a device connected to another network. If you use a Direct connection on a device while connected to another network, there are risks involved.
You must know how to ensure your Direct connection is secure. Anyone can take advantage of getting your information using Wi-Fi Direct. There are two different types of Wi-Fi Direct connections: Temporary and persistent.
A persistent connection lets you save information on your device, so it automatically connects. You can use temporary pins, too. Use newer Wi-Fi Direct connections that have more safety features, and never use them in public. Hackers are always looking for new ways to steal information. A recent bug in Linux devices lets hackers access mobile devices on Wi-Fi Direct if it has Wi-Fi capabilities enabled.
For security purposes to this functionality, many connections require the input of a PIN or require you to scan a QR code for a wi-fi protected setup. Even with these extra steps, this kind of connectivity offers a variety of advantages in a business setting.
Without Wi-Fi Direct, devices would need to share information through an access point such as a router or over the internet. Sharing sensitive data over the internet comes with security risks, as anything stored or delivered online can be intercepted by cybercriminals. Accessing a local intranet can diminish some of this risk, but it also limits information sharing to areas where a connection can be established to the internal network.
Wi-Fi Direct offers instant connectivity in any setting as long as the devices are within range of each other. This provides significant mobility in business applications. The power of Wi-Fi Direct also increases its usability. With higher data and speed capabilities, team members can easily share high-resolution video, photos, and large data files.
This is an excellent collaborative tool when working with significant information because adjustments can be made in real-time, updating on any connected device instantly. Device compatibility is rarely an issue today thanks to Wi-Fi Direct technology being available over the last decade.
