title: Arduino Sends Junk value to Android App (App Inventor 2) via Bluetooth
body: <p>I just used an arduino code to send text data to an android application which I made in app inventor. I used Bluetooth module HC-05 for connectivity.It almost works but instead of sending few characters, it sends junk data. Here's the arduino code: </p>
  
  <pre><code>   void setup()
  {
    Serial.begin(9600);
  
  }
  void loop()
  {
    Serial.println("h");
    delay(500);
    Serial.println("s");
    delay(500);
    Serial.println("o");
    delay(500);
  }
  </code></pre>
  
  <p>And here's the App blocks and Design:

  <p>And here's the screenshot when I ran the app:

  <p>I click "Show" and I get these random junk data. And the next time I click show, I don't get any data at all. Can anybody explain how to solve this ?</p>
