+<p>
+            
+            This application allows two Android devices to carry out two-way text chat over
+            Bluetooth. It demonstrates all the fundamental Bluetooth API capabilites, such as:
+              (1) Scanning for other Bluetooth devices
+              (2) Querying the local Bluetooth adapter for paired Bluetooth devices
+              (3) Establishing RFCOMM channels/sockets
+              (4) Connecting to a remote device
+              (5) Transfering data over Bluetooth
+            
+        </p>

+              (1) Scanning for other Bluetooth devices
+              (2) Querying the local Bluetooth adapter for paired Bluetooth devices
+              (3) Establishing RFCOMM channels/sockets
+              (4) Connecting to a remote device
+              (5) Transfering data over Bluetooth
