WiFiCast is an application that enables us to communicate in a way similar to the walkie-talkies using different devices connected to the same wifi network. To do that it uses multicast, a transmission data protocol that allows us to send data from an emitter to many receivers in a way that the network traffic is not dependent on the number of receivers.

WiFicast default startup mode is listening. That mode enables us to listen to what others in the network may be emitting. For us to be able to talk all we need to do is to push once the button saying “Listening”, in doing so it will change to “Speaking”.
