title: Receiving temperature reading from arduino over bluetooth and display in android smartphone
body: <p>I have to do a project whereby I have to get a temperature reading from a temperature sensor and send it over Bluetooth to an android smartphone and display the reading. </p>
  
  <p>I'm using MIT's app inventor to make the app. So far, I can connect to the Bluetooth module hooked up to an arduino uno r3 and I can display the temperature if I press the "display" button. I want the app to update the temperature reading itself without me having to press a button to update it everytime. How do I do this? This the code I have so far. </p>
  
  <p>I've tried using the timer in app inventor to update the reading automatically, but the app inventor keeps crashing after it connects to the Bluetooth module. </p>
  
  <p>The code blocks I have so far are in this link. <a href="http://www.flickr.com/photos/92242434@N07/8382878573/in/photostream" rel="nofollow">http://www.flickr.com/photos/92242434@N07/8382878573/in/photostream</a></p>
