RTC Module - issues

RTC Module - issues was created by Avocette

Like other users of Astroberry I have become familiar with the system date and time at boot being 11 February 2016, and around 17:28. I successfully adding a GPS dongle to provide real time and geographical location information. However I felt it could be useful to add an RTC module, and fitted a DS3231 unit. After following the thread 'More RTC madness!!!!!' I still could not get the RTC unit to work properly. I subsequently swapped over the Astroberry OS microSD to the Raspian one, carried out the same file edits to install the RTC module and 'hey presto' it works, maintains the real time clock as expected, and updates the system date and time on boot.
What I find most perplexing is that on swapping back to Astroberry OS, not only is the RPi system time the usual 11 February 2016 at 17:28, but my RTC Module has been written to with this date and time! Hence, instead of the RTC Module updating the system time on boot, exactly the opposite happens! Any bright ideas about what's going wrong please?

Astroberry Server does not contain any default configuration for RTC. Anything you do is custom config for RTC over defaults for Ubuntu Mate 16.04.
Just make sure the RTC is properly detected (i2cdetect -y 1). If so add custom configuration as per any guide available on the Internet.
Sorry that the answer is not helpful too much but the system does not handle RTC by default so you need to use configuration that works for other users.

There are a few RTC modules for the Raspberry Pi. The PCF8523 is a simple and inexpensive module but not a high precision device. It may lose or gain a second or two per day. For a high-precision, temperature compensated alternative, check out the DS3231 Precision RTC . It cost a few dollars more but well worth it. It is the one I use without any issues.

The DS3231 is the one that I have. I'm just glad that I got it working

I tried using the Pi Hut method (changing to DS3231) and it worked with the Raspian OS but not with Ubuntu MATE as used in Astroberry.

I’ve now found this guide on the Ubuntu MATE community forum which I shall study. ubuntu-mate.community/t/supporting-ds323...th-network-time/5711
