I have made few changes to your app:-

Firstly, I shifted the code responsible for creating the Bluetooth connection to ConnectThread .

2) Added AcceptThread responsible for listening incoming connections and ConnectedThread maintaining the BTConnection, Sending the data, and receiving incoming data through input/output streams respectively. 3) Created 2 buttons to start ConnectThread and AcceptThread.

NOTE: Make sure both the devices are paired and the device that you are trying to connect to is at the top of the list(or just remove all the paired devices from both the devices and only pair the devices that you want to connect). Also, you must start the AcceptThread before ConnectThread
