+Wi-Fi Direct MultiChat (aka Pigeon Messenger)  is a demo Android's application that try to overcome some Wi-Fi Direct's limitations.
+At the moment, the wifi diver of commercial devices doesn't allow a device to partecipate concurrently in two Wi-Fi Direct's groups.
 This app tries to overcome this limitation, indeed, a user can communicate with a large number of nearby people without an internet connection, using point-to-point communications.
 The main goal is the simultaneous management of multiple chats, queuing messages sent when the connection is not available and send them at the same time as soon as possible.
 
 Pigeon Messenger requires Android 4.4 KitKat (API 19) or higher. This choice is related to to the fact that in previous versions, this protocol was unstable and unreliable.
 
-It's important to remember that this is a demo application, so features like the management of screen's rotation, standby device, wi-fi not available and so on, are not managed as a commercial product.

+Pigeon Messenger works with good performances.<br/>
+The main problems are the "Discovery Phase" of this protocol and the Wi-Fi Direct's implementation in Android, in fact:<br/>
 1. The discovery time is too high when the number of devices increases <br/>
 2. After a certain time, a device is no longer discoverable from others, so you need to restart the Discovery Phase on all devices <br/>
-3. Sometimes, the Wi-Fi part of Android crashes and the only way to solve this annoying problem is a complete reboot of the device (this situation is recognizable when Android can't find other network in Wi-Fi Setting's app).
+3. Sometimes, especially in KitKat, the WiFi part of Android crashes and the only way to solve this annoying problem is a complete reboot of the device (this situation is recognizable when Android can't find other network in Wi-Fi Setting's app).
 
 This shows that it's possible to extend the Wi-Fi Direct protocol in Android in some particular and limited scenarios, for example a chat.

 ## Future extensions
 - [ ] Connect more clients at the same GO without limitations
 - [ ] Group chats where the GO receives messages from a client and it sends these messages to all other clients in broadcast
 - [ ] Private chats between clients, i.e. a client uses his GO like a server to send private messages to another client, because in Wi-Fi Direct the communication between clients in a group is impossible. In this case is necessary to provide security mechanisms, like encryption, because a GO should never read private messages between its clients.
 - [ ] and so on... ;)
