Hi. @roneld01 and @acpie360
I have implemented a random number generator from RF noise on my board. And it is working.
I can increase the size of my buffer from 16 to 32 bytes (or even 64 if needed), in order every time I need a seed there will be 32 bytes ready to be read from that buffer. A question, the values of the individual bytes of the random data can range from 0 to 255? Or do these bytes need to be characters only?
@roneld01 Thanks so much for your help until here.
Would mbedtls_hardware_poll look like this? What should happen when “len > *olen” , whats the commomly used values for len? Can it be limited to 32?
EDIT: Or maybe like this… Never write more than len bytes, and limit on 32.
Regards.
