SoftDevice RNG functions not working

[patjshan]

Hi All,

I am trying to use the RNG peripheral through the softdevice (i am using Version 5.0, with 14.2 SDK) with the sd_rand_... functions. I have enable d the RNG in the SDK config file and initialized it through the nrf_drv_rng_init() function (passing NULL as the argument to configure it as default) but when i run the function to generate the random value the number of bytes available keeps on being zero. I have looked at the RNG example in the SDK but that is not using the soft device functions, it is accessing the peripheral directly through the driver. Can anyone provide some insight on the sd_rand functions?

Thanks,

Patrick

Hi,

It shouldn't be necessary to call softdevice functions directly as the RNG driver works with softdevice enabled:

Not correct, use Softdevice API instead.
