Here is my Scenario:
I have one Device that has app "a" installed on it.
I have one or more Devices that have app "b" installed.
I would like the devices with app "b" to be able to send a signal to app "a" to "register" the device. From app "a" i would like to be able to send messages back to some or all of the the devices. i was wondering if anyone knew any examples of this and the best way to go around doing it.
I have looked into Text Message and Bluetooth but I am looking for something along the lins of Direct connection, treating app "a" as a server. I have looked briefly into sockets and was wondering peoples opinion of the best way to do this.
Thank you in advance.
