Is there anyway by which an app can be built using Wifi Direct, By which an un-targeted message packet can be sent over the network, So that anybody can pick it up and process. I mean a packet needs to be sent without any target so that everybody in range can read it and act accordingly. And the system should be such that anyone can enter and leave freely.

PS: I strictly want to use Wifi, But I am Flexible with language and Libraries.

  • @adelphus, I guess Android doesn't provide native support for Ad-Hoc's. – ksdme Aug 22 '15 at 16:37
  • if the message is short enough, you could use the normal service discovery for this. – Dr.Jukka Aug 24 '15 at 08:11
  • @ Dr.Jukka, I can't use Service Discovery, Since it takes long time to do so. – ksdme Aug 24 '15 at 14:00
