Hi, everyone,

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

I am working with Simplicity Studio IDE with MbedTLS and I am currently working on a project with a BGM13P32. I plan to perform a key exchange via bluetooth with the Diffie Hellman protocol. To start my project, I need an entropy source. I read the following on the BGM13P32 documentation "The TRNG is a non-deterministic random number generator based on a full hardware solution. The TRNG is validated with NIST800-22and AIS-31 test suites as well as being suitable for FIPS 140-2 certification (for the purposes of cryptographic key generation)."

And I also read about the Random Number Generator "The Frame Controller (FRC) implements a random number generator that uses entropy gathered from noise in the RF receive chain.The data is suitable for use in cryptographic applications.Output from the random number generator can be used either directly or as a seed or entropy source for software-based random num-ber generator algorithms such as Fortuna"

Knowing this, how can we use this to create entropy and then create a sequence of random numbers? I need to implement the MbedTLS_hardware_poll() function? Do I have to add another entropy, like real timing for example

As you can see I am a bit confused actually. Can you help me out?

Thanks in advance, and take care of yourself !
