Since we are talking here about "chat" / "messenger" applications, why not use something
which is really free, open, and standardized and available since years ?
(Note: WhatsApp (aka Facebook) and telegram are not free/open source.
They are commercial proprietary and do with your data as they please)

I'm talking about XMPP (formerly known as Jabber), specified in RFC 6120, which is not tied to any company.
There are lots of free xmpp servers out there https://xmpp.net/directory.php
and you can even run your own XMPP server if you like.
XMPP is like email. You have one address on any xmpp server, and you can talk with anyone regardless of
their xmpp servers they use. The messages are relayed.
Details https://en.wikipedia.org/wiki/XMPP

There is a very good and actively developed open source app for Android for it, called "conversations".
Homepage: https://conversations.im/
It is free when you install it from the open source repository f-droid: https://f-droid.org
google playstore: https://play.google.com/store/apps/deta ... versations

There are desktop clients as well, so you can seamlessly use the chat on your phone or desktop,
e.g. kadu http://www.kadu.im/w/English:Main_Page

Why am I mentioning this here ?

Because in 3.15 there is a new CTRL extension which implements the XMPP protocol and with this
you can create messages from any server, create public or private chat-rooms and you can even
send messages from some other client to your server if you like.

Does that sound interesting to you ?

wow sounds cool .. thats a good alternative for GCM (Google Cloud Messaging)

it's maybe possible to add libotr?

I'll have a look

Are there any information about the xmpp ctrl extension?

I can't find any information in the 3.15 help file.

[mkoller]

I attach here a preliminary documentation. The time for 3.15 was too short to fully test/integrate it, so the plugin is currently a technical preview,
but we welcome any feedback! https://www.winccoa.com/fileadmin/image ... s/docu.zip

[netmonitor]

Thank you for the fast answer!

I have checked your attachment, but the described functions are not available in 3.15.

Is there a library which I have to include?
I have searched the installation directory for something called XMPP, but i haven't found anything

Can you tell me, how i get started to use these functions?

[mkoller]

The functions are available with the CtrlXmpp CTRL extension.
I have the following in my 3.15 installation (from WinCC_OA_3.15-base-sles-0-1.x86_64.rpm - that should be the official release):
/opt/WinCC_OA/3.15/bin/linux-rhel-x86_64/CtrlXmpp.so

[netmonitor]

I found it, don't know, why I haven't seen it before.
Thank you!
