Question regarding versions

1

Hi, I’m having installed PlatformIO successfully so far and was already able to run some code on an ESP-12E dev board. I was trying to access some low level SDK function, for instance system_get_sdk_version(), declared in “user_interface.h”.

I’m getting “1.5.3”. Can anybody explain to me, what this version number describes?

Regards

OK, suppose, it is really the SDK version :slight_smile:

Is there a way to upgrade to the latest SDK (2.x, I suppose NON_OS_SDK?)

Regards
