Hi Camilo,
I'll ask what happened to the KSDK web_hvac example/demo for FRDM-K64F.
EDITED: Please note that the TWR-K64F does have the web_hvac listed.
C:\Freescale\KSDK_1.2.0\examples\twrk64f120m\demo_apps\web_hvac
There is support in MQX_4.2.0 for the web_hvac on FRDM-K64F Freedom board as FYI.
Regards,
David
