Calendar sync not wokring

Calendar events aren't syncing to with my Bangle.js 2 (it used to work a while back, but I didn't need them back then).

The GadgetBridge log looks promising:

15:08:10.741 [main] INFO  n.f.g.e.CalendarReceiver - event id=418 is yet unknown to device id=1

and then one of the following lines per calendar event to be synced:

15:08:10.784 [main] DEBUG n.f.g.s.DeviceCommunicationService - Service startcommand: nodomain.freeyourgadget.gadgetbridge.devices.action.add_calendarevent

But nothing appears on the Bangle.js - the android.calendar.json remains empty.

I've looked at the "device Debug log" (with "Debug" set to BOTH on the watch), but all I found related to calendar syncs was:

{"t":"force_calendar_sync","ids":[]}

I've also tried to completely remove the device from Gadgetbridge and re-connect.

What else can I do to help with troubleshooting?

Maybe you could provide a section of the Gadgetbridge log from right after it sees force_calendar_sync ?

That line shows the Bangle is reporting that it doesn't have any calendar events, but you should see {"t":"calendar" lines from Gadgetbridge as it pushes data to the Bangle, and likely after that some error from the Bangle if there was an issue.

If that's not happening it might be a Gadgetbridge config issue. When you click on the gear icon next to your device in Gadgetbridge for "Device specific settings", do you see Sync calendar events is enabled, and nothing is blacklisted?

Here's the Gadgetbridge log from just before "force_calendar_sync" to the end:

"Sync calendar events" is enabled in Gadgetbridge. I have a few calendars black-listed, but I've also tried a sync with no calendars black-listed - same result.

There are no {"t":"calendar" lines (I assume in the Bangle's "device Debug log").

Ok, thanks - you should see a UART TX line in that same log you posted if anything was being sent to the Bangle...

So it seems this is an issue with Gadgetbridge, just not getting your calendar events... And you're sure it's not just that you don't have anything? I think it only syncs 48 hours in advance or so.

If you go into Apps on your Android phone, have you given it all the relevant permissions?

Yup, Gadgetbridge has all permissions. It also lists all available calendars under the blacklist selection. And I get the following log entries if I create a new event:

19:09:08.117 [main] INFO  n.f.g.e.CalendarReceiver - event id=419 is yet unknown to device id=1
19:09:08.137 [main] DEBUG n.f.g.s.DeviceCommunicationService - Service startcommand: nodomain.freeyourgadget.gadgetbridge.devices.action.add_calendarevent

But not the UART TX lines you've mentioned.

I'm not sure if this is related, but it's strange that only one of 4 black-listed calendars is mentioned in the logs:

19:09:07.873 [main] INFO  n.f.g.u.c.CalendarManager - Loading calendars_blacklist
19:09:07.873 [main] INFO  n.f.g.u.c.CalendarManager - Loaded calendars_blacklist has 4 entries
19:09:07.899 [main] DEBUG n.f.g.u.c.CalendarManager - calendar ...@gmail.com/Holidays skipped because it's blacklisted
19:09:08.005 [main] DEBUG n.f.g.u.c.CalendarManager - Reminder Method: 1, Minutes: 60

If I remove that calendar from the blacklist, the log correctly states Loaded calendars_blacklist has 3 entries, but there are no "skipped" log lines for the other 3 calendars.

I've managed to compile the latest Gadgetbridge from source (banglejsDebug), and the calendar syncs fine with that version - all expected events show up on the Bangle, there are nowUART TX lines and everything.

Previously, I've had the latest version from F-Droid installed (0.81.0-banglejs). I didn't review the changes since then, so I can't tell exactly what could be the issue.

Anyway, maybe an update to the F-Droid version might be due.

Anyway, maybe an update to the F-Droid version might be due.

I believe it auto updates when the Gadgetbridge project tags a new stable release (which I suspect isn't very far off).

I could be wrong, but I think you can just download nightly builds from https://freeyourgadget.codeberg.page/fdroid/repo/ ?

Right - I had forgot about those.
