No need to be rude. Looking at examples provided by st https://www.st.com/resource/en/user_manual/dm00298232-bluenrg1-bluenrg2-development-kits-stmicroelectronics.pdf '20.9 RTC examples' I can see that RTC in sleep mode is only simulated by virtual t...
In my case bluenrg-2 is host (standalone SoC Mode) and unfortunately as far as I know there is no RTC in low power mode. Hence need to use virtual timer. I wonder if this is accurate enough to track time for longer periods.
