Best Way to Clear Spark Core Flash

I just flashed my first Spark Core with one of the sample apps and am curious what’s the best way to get a Spark Core clear again without resetting it? Is there any problem with flashing the Core with empty code?

There is technically no empty code since the setup() and loop() is part of a larger code that is invisible to the user.

Of course you can flash and empty code but the core will simply go online without any functionality. :wink:

Makes sense - thank you!
