Question

Set RTC without resetting HW timer server?

My STM32WB5MMG application interfaces with a GPS receiver. Ideally, what I would like to do is to update the RTC date/time every time I get a timepulse signal from the GPS, so that the RTC date/time is always as close as possible to GPS time. However, my application also uses ST's HW timer server, and when I update the RTC date/time, it seems as though this also resets timers in the HW timer server, so that those timers do not trigger when expected.

Is there a way to update the RTC without interfering with HW timer server timers?

Thank you!
