wifi-direct

问题 App crashes while sending data over a socket using wifi p2p connection I am testing a simple chat application between HTC_Desire_10 pro (running Android 6.0) and OPPO A83 (running Android 7.1.1). I have the same app running on the two devices. The app first turns wifi on, then starts discovering peers on a users click event. The user can choose the device they want to connect to from a dynamically generated peer list. The two devices are able to connect successfully. I am able to send a text

问题 I am developing demo to send and receive data through WIFI DIRECT . It works fine multiple clients are connecting to the owner and all clients can send data and also Group owner receives those all data from clients. I have used wifi direct demo of google. But the problem is, I am not getting how to send data from Group owner to all or particular client(s). I tried to do this after storing client's IP but it is not working. I am searching for this since last two days but haven't got proper

问题 In iOS 8, Apple allows us to connect to a device via Wifi direct and share wifi network credentials with it. We can do it in wifi settings page but also in an app. I'm trying to launch a scan to find wifi MFI devices. I can see those in the wifi settings but not in app. Here is how I do this: EAWiFiUnconfiguredAccessoryBrowser *_wifiBrowser = [[EAWiFiUnconfiguredAccessoryBrowser alloc] initWithDelegate:self queue:nil]; [_wifiBrowser startSearchingForUnconfiguredAccessoriesMatchingPredicate

问题 I have an Android app that needs to let multiple devices connect. One device should act as the group owner and issue instructions to all of the clients to do specific things. I suppose it's comparable to a wireless handheld game where one player is the host. I have a couple of questions so I will try to keep them concise. Even an answer to just the first would help. First, I've successfully paired a single server and single client phone using sockets. I did this using Android's Wi-Fi Direct

问题 Can I connect a WiFi Direct enabled device to any other device which doesn't have WiFi Direct feature but supports WiFi hotspot connection? Does WiFi direct uses specialized hardware to be present on both devices? Will network discovery work in such cases? 回答1: It is possible. Code taken from a talk I gave at Droidcon UK 2013. You need to call the createGroup(WifiP2pManager.Channel c, WifiP2pManager.ActionListener listener) method of the WifiP2pManager class. This will create a Wi-Fi Direct

问题 I've got a problem using wifi direct. I managed to connect 2 devices and send data from the client to the group owner, because the group owner ip is the one that everybody knows. I managed also to find out the IP of the client and pass it to the group owner but I can't send data from the group owner to the client, even if it should be simmetric. I'm using Intent and startService() to send data and AsynkTask for receive. Using only 2 devices I noticed that the client IP is always the same (192

问题 I'm a bit confused about the new Wi-Fi Direct feature in Android ICS. Is it possible to create a P2P group with multiple devices, and send multicast packets from a source peer to the other peers? Unfortunately, I don't have any devices that are Wi-Fi Direct enabled, so I can only browse the examples that I find online. In these examples, I could only find peers establishing 1-on-1 connections. So, is multicasting possible? 回答1: Is it possible to create a p2p group with multiple devices ?
