Hi,
finally I got it working. But I don't know why...
There is no firewall active. From the browser on the tablet I can call the url
http://192.168.10.7:8080 (show GUI) and
http://192.168.10.7:8080/odps (gets XML).
Under "settings" in CC there are "wireless" and "Content Server". First try was to put IP-address and port number under "wireless". Now I switched to "Content Server" and put the settings in this form.
Now it is working. I don't know the difference between the settings, but anyway....
Thanks for Your support!
Best regards,
Karsten
