Using RNG with SoftDevice disabled

[ImQ009]

I have my devices programmed in a way, that they decide whether to enable SD and transmit via BLE or to keep it disabled and start operating using Gazell. In this case I need SD to be disabled and use RNG. Can I do it?

Thanks in advance.

YES :) Softdevice disable will mark all peripherals as unprotected, you can just consider that it doesn't exist except that it takes space in flash

Yes, when you disable stack, you cannot use its API anymore. Few exceptions, the ones defined in nrf_sdm.h and everything that is below SOC_SVC_BASE_NOT_AVAILABLE enum in nrf_soc.h. The exception in these is that they are used to enable/disable softdevice and some flash operations.
