LWM2M Carrier Library and date_time library hard fault

user106788

I'm trying to integrate my application with the LWM2M Carrier library, and experiencing a hard fault when calling date_time_update_async(). This happens even if I call the function after I receive the event LWM2M_CARRIER_EVENT_LTE_READY. Anything obvious I'm missing?

    What is the hard fault that you receive?

    When I get to work today, I’ll recreate it. The fault was not printing to the logs so I’ll have to enable it in prj.conf

    I tested with running NCS v1.7.0 lwm2m carrier sample, adding date time library.

    Gotcha, good to know it’s just an issue on my end. I’ll reproduce in a little bit and get back to you with a better log. Thanks for your help

    Sounds good. Make sure to add CONFIG_DATE_TIME=y in prj.conf and add #include <date_time.h>
