Hi,
is the mbed-tls framework not supported by VisualGDB or the current mbed-bsp (5.4.2R2)?
I tried to implement a project I used with anoter IDE into VisualStudio 2017 with VisualGDB, but couldn’t find a option to enable the mbed-tls framework.
It would be easy to just reference the necessary folders from your bsp where the headers/sources for the tls are present, but I think it would be best to use a build-in option, if available.
