On my device only manual syncing of calendar with google works.

I tried to create test event and wait for 24 hours. During that period internet connection was missing no more than 3 hours. But still after a day test event were not synced, but it got immediately synced when I triggered manual sync.

I thought to myself: Ok, fine, I am a brave one. I can make duct tape solution: peek what process performs sync and schedule it execution several times a day with timedclient-qt5.

So I strace -e trace=file,process -ff -p $(pidof jolla-settings) to find what jolla-settings launches to perform sync.... and it does not look like it calls external tool! jolla-settings just mangles sync DBs by itself.

It does not make sense to me. Is background sync implemented at all? If it is implemented than how often it should be triggered by OS? Is there a way to trigger it from script?

UPD: Guys, this is just insane. I have found solution. There is config file /etc/buteo/profiles/sync/google.Calendars.xml and in this file syncing is just disabled :-D I've changed two lines in this file

And rebooted the phone. phone (Update: most likely running systemctl --user restart msyncd.service should be enough). Now background sync works. Probably interval should be increased to bigger value to conserve power. I believe suppose interval is minutes. Anyone care to give a link to config file spec?

I can't believe I was suffering for almost a year without sync due to such simple misconfiguration.
