如何通过Blutooth HC-06在TextView上将Ping传感器数据获取到Android Studio

Question

I have managed to set up the connection between my arduino and the App with the help of Instructables blog . The connection is set but i need the sensor output value of the ardunio to be displayed on a TextView. This is the Arduino code . How do i program my Android studio program to read the output value of the serial monitor in the Arduino?

Answer 1

Okay, in the tutorial shows how send data from the app to arduino, but not how receive data from the arduino to your app for do this, you will need:

1. Send data from arduino by HC-06.
2. Receive and decode your data in the app.
3. show decoded data in the TextView.

a litle example for do this.

In Arduino: can be the example of the arduino page you must only make sure that HC-06 is properly connected in Serial port.

In the app code you can use this code to receive data, only change the name of SocketBT instance, for the instance that you need.

 private class TareaLeer extends Thread
{
    @Override
    public void run()
    {
        while(SocketBT.isConnected())
        {
        InputStream inputStream;
        try {
            inputStream = SocketBT.getInputStream();

            byte[] buffer = new byte[256];
            if (inputStream.available() > 0) {
                inputStream.read(buffer);
                int i = 0;
                for (i = 0; i < buffer.length && buffer[i] != 0; i++) {
                }
                String strInput = new String(buffer, 0, i);
                String Recepcion = strInput;

                Log.d("Recibi",Recepcion);
                //Here you can pass the value of recepcion to any globlal variable and show in TextView

            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
    }
    Parar();
    }
}

for show it on TextView you can do this.

MyTextView.setText(Recepcion);

this is a very general explanation, for do it , you need know how android code works basically, but is a good example for start Android and Arduino Programming.
