Deep sleep

On the DA14580, we have been using deep sleep and a wakeup mechanism that relies on a level transition on a GPIO. This has worked very well and reliably. Recently, we wanted to incorporate an additional feature that requires a timed wakeup every 1-3 minutes. This is achieved by putting the device into deep sleep mode just prior to setting a timer using app_easy_timer. This is working generally as expected however I'm noticing that every 10 seconds the device wakes up on its own very briefly and goes back to sleep.
