So, there is a function in BluetoothSocket called isConnected:

    /**
     * Get the connection status of this socket, ie, whether there is an 
active connection with
     * remote device.
     * @return true if connected
     *         false if not connected
     */
    public boolean isConnected() {
        return mSocketState == SocketState.CONNECTED;
    }



I noticed that if my Android has a Bluetooth connection to my computer and 
I power down my computer, isConnected still returns true.  Anyone know if 
this can be fixed?  I'm not sure if there's a Bluetooth heartbeat or not.
