Reading data from bluetooth device in android

by

I use DataInputStreams instead as you can do a readFully() method which waits to read a certain number of bytes before returning. I setup the BT connection like this:

BluetoothDevice btDevice = bta.getRemoteDevice(macAddress);
BluetoothSocket btSocket = InsecureBluetooth.createRfcommSocketToServiceRecord(
                    btDevice, UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"), false);

btSocket.connect();
InputStream input = btSocket.getInputStream();
DataInputStream dinput = new DataInputStream(input);

then later on when I want to read I use readFully:

dinput.readFully(byteArray, 0, byteArray.length);
