Constructor Definition

    /// Activity = Current Activity or Target Activity, Interval = On Read Interval Time (ms),
    /// RWBufferSize = I/O Buffer Size, read = OnRead Method
    public BT(Activity activity, int Interval, int RWBufferSize, OnReadMethod read)

for example

BT  bt = new BT(MainActivity.this, 500, 1024,new BT.OnReadMethod() {
                    @Override
                    public void OnRead(byte[] data) {
                      ///Do Something
                    }
                });

Connect Method Definition

    ///device = target device for connection, _flagIO = bitflag (INPUT, OUTPUT) for Open Stream
    public synchronized void Connect(BluetoothDevice device, char _FlagIO)

for example

   //For Input
   bt.Connect(device, BT.INPUT);
   
   //For Output(
   bt.Connect(device, BT.OUTPUT);
   
   //For Input/Output
   bt.Connect(device, BT.OUTPUT | BT.INPUT);

Write Method Definition

    public synchronized void Write(byte[] data)

Other Method

getDeviceList : return Set < BluetoothDevice >

CheckWithEnableBluetooth : Activate Bluetooth

Disconnect : Disconnect Connection

OnRead Method Interface Definition

    public interface OnReadMethod
    {
        void OnRead(byte[] data);
    }

Issue

전송측과 수신측의 전송 속도가 같아야 데이터가 온전함(데이터가 누락되지 않음) -> 추후 개선 가능함
오가는 데이터가 클수록 전송과 수신측의 Interval이 길수록 안정적임. (1번의 이유 때문에) -> 개선 가능함
