I am using the nrf52840 with freertos and bluetooth (based on the HRM example). Application is designed to sleep for a set period of time before the RTC timer wakes the MCU. I am using sd_app_evt_wait() to put the MCU in the systemON sleep. But i see that the MCU is waking up before the expected time. how can i find out whats causing the wake up? Could the RTC1 used in the Freertos be causing the wake up?
Thanks
