Can I program the bluetooth module itself?

Yes, you can re-program the bluetooth module using AT commands. Here's a way to do that wwith your Sparki robot by using a custom program.

Plug in the bluetooth module as you normally would, and upload the attached program to Sparki.

After the module is plugged in and Sparki is reset, the RGB will change to yellow as it attempts to program the bluetooth, then green for a good re-program, or red for a bad re-program.
