I mean the simplest possible scenario: one of users starts the app in host mode, and others are in client mode, they can search for nearby hosts (up to 2-3 meters distance) and join selected host and then exchange data with the host. It should work cross platform.

Is this possible at all?

  • Bluetooth does not allow for cross-platform communication. http://stackoverflow.com/questions/18884705/transfer-data-between-ios-and-android-via-bluetooth Is there another option? – PawelRoman Jul 05 '16 at 11:18
