nrf_sdh_enable_request takes quite a long time to end (S132 6.1.1)


I'm working on nRF52832 and i'm porting the SDK15.3.0 (i was currently working with SDK14.2.0) but i'm facing something strange with the function : "ble_stack_init" 

Indeed, it is very long to end compared to the one in SDK14 and i don't know why. I know this function enables the softDevice but why it is so long. I tried to add more RAM to the softdevice but i didn't change anything. I'm using the softDevice S132 6.1.1.

This function takes around 2 or 3 seconds

Thank you in advance,

Best regards,
