sorry, I wrote the message from within the "discussion" tab of a training and I thought my message was pointing to it.
I am referring to the Embedded Security Learning Path, MOOC Part 3 - Secure cloud connectivity with SBSFU and STSAFE-A110. Differently from the other Sections, I can't find under the "Materials" tab any file (Presentation and/or hands-on package). I guess there is no hands on for this section, so I am only interested in the slideshow.
