Dear all,

I wonder if it is possible to connect the AI2 Companion to our own
AI2 server through the internet like MIT? We are building a local
service for our town. The AI2 Compamion of the users are not in the
same Wi-Fi network with AI2 server.

You will need to run your own TURN server to support that and update the appengine/war/WEB-INF/appengine-web.xml configuration to point to the server. We provide default credentials for a server at MIT but this may result in significant latency depending on your bandwidth and location.

Regards,
Evan

Dear Evan,

I assume you by appengine-web.xml configuration, you mean
use.rendezvousserver? Because I do not find a configuration for TURN
server.

So I can put my TURN server in use.rendezvousserver? Or should I
run my Rendezvous server but not TURN server?

My apologies. I thought we had put that configuration into the appengine-web.xml file, but that isn't the case. The appropriate lines to change are:

blocklyeditor/src/replmgr.js: 83-85
components/src/com/google/appinventor/components/runtime/WebRTCNativeMgr.java: 216-218

Evan

Thank you.

However, I still cannot get it working. Should I set up my
Rendezvous server and set use.rendezvousserver, too? But I cannot find
a Rendezvous server on the internet that I can use.

A version of the rendezvous server code is in the misc folder in the sources. You'll need to set things up both in YaVersion.java and appengine-web.xml so that your instance and your companion know which server to talk to. Otherwise, they will go through the MIT servers.

1.修改 war\WEB-INF\appengine-web.xml中

<property name="use.rendezvousserver" value=""/>

为

<property name="use.rendezvousserver" value="自己电脑IP:8888"/>；

2.修改桌面版AI伴侣、手机AI伴侣的Rendezvous Server为自己电脑IP:8888

Thanks all. I finally got this working. *^_^*

The key missing component for the AI2 server to connect to the AI2
Companion App is not the TURN server, but the Rendezvous server. The
Rendezvous server is in the appinventor/misc/rendezvous folder. After
starting the Rendezvous server by the instruction in the README.md file
in the rendezvous folder, I need to modify the
war\WEB-INF\appengine-web.xml file and set the use.rendezvousserver
property to the running Rendezvous server, in order to work.

Also a pitfall: Both the AI2 server and the Rendezvous server need
to be HTTP, not HTTPS.
