Pushbutton to send a command to a bluetooth controlled relay

[Muttleytm]

I want to build a very simply app that will act as a garage door pushbutton switch emulator and work with bluetooth controlled relay.  I would like the relay to momentarily close just like the hardware switch has it do.  I have the code I need to send it to do this and can do it using the terminal like software the relay provided, but, it is sort of inconvenient.

I just need the ability to open the app, connect the my bluetooth relay then just push the button to activate the relay.

I have bluetooth terminal on my device and it seems like I could just have the pushbutton launch a script to do this using bluetooth terminal, but, I've never down any sort of programming with android.

So far using the app inventor I've put a pushbutton on the screen, but, I don't see how to add an action to a click event or connect the to the device.

Any ideas?

TIA

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook   http://www.appinventor.org/book2 ... the links are at the bottom of the Web page.  The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro  and the aia files for the projects in the book are here:  http://www.appinventor.org/bookFiles  

How to do a lot of basic things with App Inventor are described here:  http://www.appinventor.org/content/howDoYou/eventHandling  .

Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the
