Is there a way to programmatically control the LED on the Freematics ONE? #33

I want to use the LED to show whether logging is in progress or not; and also to blink on certain events, such as errors.

However, I can't achieve that using LED_BUILTIN. It seems like the LED is wired to the serial TX?

where did you get that "LED_BUILTIN" constant?

I couldn't find it in the library files, where is it?
