Modifying Bluetooth Chat

I started out trying to pull the android bluetooth chat application from the developer website....BAD IDEA. I spent quite a bit of time commenting this out, adding a toast here and a if then there. That one is built for a different sdk version than I'm using, so my recommendation would be to pull it from the examples folder in the sdk download.

Well I finally grabbed the bluetooth chat application from the sdk examples folder (when you download from google). After about 5 minutes I tried loading the default app on my phone and touchpad, it worked just fine. I then changed ONE LINE of code and my arduino can talk to my android devices with bluetooth. What line say you? This one:

In the BluetoothChatService.java
From

private static final UUID MY_UUID = UUID.fromString("fa87c0d0-afac-11de-8a39-0800200c9a66");

To

private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

That's it that's all it took. Apparently that UUID from what I've been able to gather is for the bluetooth serial interface, so that's all I needed.

Here is video proof of the application in action.

Good luck and let me know if you have any questions.
