Hardfault when using exemple with the nrf_calendar

[Mauricio Farina]

Hi Nordic Team,

I'm having some trouble with using the nrf_calendar with the softdevice...

I'm using the SDK V12.3.0 and softdevice s130 V2.0.1 and the exemple ble_central/ble_app_uart_c

I've added the function nrf_cal_init() rigth after the ble_stack_init(), but when I run I'm getting a hardfault inside the  nrf_cal_init().

Any ideas on how fixing it?

We need more information

Do you have any debug information? Stack trace, hardfault ID, etc. ?

What RTC instance are you using for the calendar?

[Mauricio Farina]

I'm using the RTC 0

I made a demo project that shows what happens...

RTC0 is reserved for the softdevice and cannot be used by BTLE application code.Try using RTC1.

I’ve already tried the RTC1, but the error persists

Just realized you're using a library that's not a part of any nordic SDK.
