Hey Hung Bui,

I Removed that implementation , and that works as expected. I am trying to make the device to sleep mode leaving some of peripherals (SPI, RTCs ) to be turned ON. I need to turned On the softdevice on a GPIO interrupt.

Thanks

Prakash

Hi Shimmer,

I think it's a bug/limitation with our implementation. So basically we will try to disable softdevice before we enter deep sleep mode (System OFF) to be able to write to GPREGRET2 retention register that the bootloader doesn't need to check CRC.

You can remove this implementation it's not really needed in your case.

May I ask why you want to disable the softdevice ? If you want to change the advertising data, you can simply stop advertising and change.
