RTC time does not survive WDT
-
We have a solar powered project that saves time stamped data (arround 5 datasets per minute) to SD and send it via a mobile WiFi hotspot that is "driving" to the node in a weekly base to a server.
Now we discovered that a wdt reset does reset all time information and time does not survive the watchdog. So time stamping is no more possible after a WDT event.
Any change to keep the time? Or is the only solution an additional external RTC?
