Advertising interval expiring and resetting chip , but losing RTC information

[dawime]

Hello, I am developing an application that requires the device to keep track of time with the RTC. I am using an app timer driven by the RTC to provide me with a 1 second increment to maintain the time. My issue comes when the advertising interval expires, and the device powers off.

What is the best way to maintain the lowest power setting, while not completely resetting the device? Or at least keeping the time information to be retained for the next wakeup? Thanks

Hi,

Is there a reason why you are resetting the chip when advertising expires? why don't you use sleep mode if there is no activity?

Look at one of our examples to see how nrf_pwr_mgmt_run(); is used.
