Hi, My application always stops at the end of ble_stack_init() exactly at:
return sd_nvic_EnableIRQ(SWI2_IRQn);
of the function softdevice_handler_init.
My board does not have a low frequency external oscillator this is why my clock source is set to "NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION"
