I want to develop an app, which will be running on tablets with Windows 8 (RT). One tablet with this app should be a "master" tablet and this tablet will communicate with other tablets "slave" (running same app). Master tablet should send data to slaves tablets (slave tablet display this received data) and slaves tablets will send data to master. Master collect this data and create some graph etc... I hope you understand. (resume: several same W8 RT app communication with each other)
Can tablets with W8 RT (running same app) communication WI-FI Direct? What´s possibilities are in C#?
Thx for every answer.
Windows 8 includes a capability to help you establish connections between copies of your app running on different devices. That capability is called PeerFinder.
Currently PeerFinder can find other devices using NFC (tap the two devices together) or using WiFi if both devices support Wifi Direct. After the initial handshake, both devices communicate using sockets.
The Proximity Sample shows basic use of PeerFinder: http://code.msdn.microsoft.com/windowsapps/Proximity-Sample-88129731
PixPresenter is a sample app that uses PeerFinder and exchanges images between devices: http://code.msdn.microsoft.com/windowsapps/PixPresenter-Code-sharing-39ed631f
PeerFinder.SupportedDiscoveryTypes tells you what methods are currently available for discovering other devices: http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.proximity.peerfinder.supporteddiscoverytypes
Hope that helps.
