[mbed-tls] Open & Read a file with a BGMQ

Morning,

First of all, I hope you are all healthy during this difficult time.

I am working with Simplicity Studio IDE and with Mbed TLS and I am currently working on a project with a BGM13P32. I plan to write in a file some parameters that will allow a key exchange by bluetooth (Diffie Hellman Protocol). I intend to make the BGM13P32 read this file, and these data to allow a key exchange. Is it possible to do that? If yes, how?

Because I'm a total beginner

Thank you, and take care of yourself !
