Hi there!
The documentation defines two possible return values for sd_rand_application_vector_get : NRF_SUCCESS and NRF_ERROR_SOC_RAND_NOT_ENOUGH_VALUES. I am wondering in which cases the latter is returned. The docs themselves are not very specific unfortunately:
"No bytes were written to the buffer, because there were not enough bytes available."
So I have two questions:
- At which rate are new random bytes (roughly) generated?
- Does the chip need code control to generate new bytes? In other words could I do something like this:
int err = -1;
uint8_t randomValue;
while(err != NRF_SUCCESS){
err = sd_rand_application_vector_get(&randomNumber, 1);
}
//Do something with randomValue
or would the chip be stuck inside the loop forever?
Thanks!
Jakob
