RTC not working proper when BLE stack running

[Alan Ajit]

Dear Nordic,

            I am try to implement RTC(nrf calendar implementation) in BLE example(SDK 13.0). both are working independently fine but combination of works fails RTC when ble starting. can you help me to solve this issue (nrf52832 DK board are used).

Hi,

The nrf5-calendar-example is by default configured to use RTC0. RTC0 is also used by the SoftDevice, so you should change the calendar example to use RTC2 instead. This  could be done in nrf_calendar.h like this:

#define CAL_RTC                 NRF_RTC2
#define CAL_RTC_IRQn            RTC2_IRQn
#define CAL_RTC_IRQHandler      RTC2_IRQHandler
