Is the RTC of FX30 battery backedup?

Hello,

I am using an Fx30 with the official firmware (R13.1.2.004).
I have update the date manually and with NTP, and used “$> cm rtc set”.

But after a power off, if the GSM is not present, I do not have the date any more.
the system date is at “Sun Jan 6 00:13:00 UTC 1980”, and “cm rtc read” returns “01 Jan 1970 00:13:55”.

If the rtc is backed up by a battery, how should I do to save and retrieve the time?

Thanks, Christian.

Hi,

There is no backup battery for FX30 RTC.
The system date has to be updated at each startup using NTP or any other way.
