Hi,

nrf_log module doesnt work now.. I am working on it, mean while can you please check this out..

this was the output when i used int datatype

EDIT : I am getting the same result using the character array pointer as well

below is the code i used for character array

 char k[16];
        for(int i = 0; i < sizeof(nrf_cal_get_time_string(true)); i++) {
        k[i] = nrf_cal_get_time_string(true)[i];
        }
      err_code = ble_nus_data_send(&m_nus, k, &lendt, m_conn_handle);

Hi 

How do you reset the time to start with?

I will try to merge the calendar example with the ble_app_uart example to see if I can reproduce your issue. You should hear from me soon ;)

Hi, 

I don't know how to reset the time, But i did try the following function from the same library :

uint32_t year = 2020;
uint32_t month = 8;
uint32_t day = 14;
uint32_t hour = 20;
uint32_t minute = 5;
uint32_t second = 55;
nrf_cal_set_time(year, month, day, hour, minute, second);

But this gave me an error.

Thank you , I am awaiting for your reply

Hi again

I was able to merge the calendar functionality into ble_app_uart, and seem to be able to send time strings successfully. 

The critical change I had to do was to modify nrf_calendar.h to use RTC2 instead of RTC0, since RTC0 is used by the SoftDevice and RTC1 is used by the app_timer module. 

Here is the code for reference:

ble_app_uart_calendar.zip

Hi, Thanks a lot i am able to get the right output now !!

I had another question, so does this time change real time? or does it remain constant?
