Hi,

I have question what type of randomness I will get from that function ezspGetRandomNumber()? It is pseudo random number or truly random number (based in noise from antenna)?

How is generated seed for that function? There is possibility to get the true random number form EFR32MG1?

Thanks for information.

EFR32MG1 is a multiprotocol 2.4GHz radio from our competitor, Silicon Labs: https://www.silabs.com/documents/public/data-sheets/EFR32MG1-SF-DataSheet.pdf

Which Cypress device are you using with the WICED Studio SDK?

Hi.

I think you are on the wrong forum. This is not a Cypress Device.

Thanks for answer but I don't think that it is connected only with device. I am a little bit confused because in WICED SDK I've read in comment in SDK that function ezspGetRandomNumber() returns pseudorandom number. But the fact is that  ezspGetRandomNumber() return the value based on the noise of antenna from EFR32MG1 module (I have read comments in code). So it should be random number not pseudorandom number. But there is lack of proper documentation where I can find the acknowledge of my investigation and observation.
