Integration of kdeconnect with Kaddressbook/Koranizer?

[A. F. Cano]

Hi,

I've been using Kaddressbook and Korganizer with a radicale server on my
FreedomBox (www.freedombox.org).  Address book, todo list and calendar
items were synchorized between various KDE computers and 2 android
phones.  The KDE computers still work great, but the old android phones
stopped synchronizing since a new upgrade of the FreedomBox software
disabled SSL v3.

Time to find another solution.  Installed kdeconnect on both phones and
on one of the KDE computers.  Testing with one phone and one KDE
computer, the devices pair just fine.  All the available plugins are
visible and selected, except the "inhibit screensaver" and "send
notifications"  However, I cannot get the addressbook to synchonize with
the phone.  It is currently empty on the phone, and clicking the
"Refresh" button on kdeconnect does nothing.  It seems it should.  Am I
missing some step?  I've searched on the web and found no answer.  While
SSL v3 was still working, it was a simple matter to set up DAVDroid and
it immediately downloaded the address book, calendar items and todo
lists to the phone.  Kdeconnect seems so be able to sync even more, but
there seems to be a problem, or I'm missing something obvious.

The phone is a samsung galaxy mega GTI9152 with android 4.2.2.  The
computer runs debian stable, up to date and some features of kdeconnect,
like using the phone as a mouse pad to move the computer cursor work
just fine, but not the sync of the kdepim data.

Any ideas? What can I try to debug this?

Thanks.
