Hi, Need Post this HTTP/XML command: http://192.168.150.132/services/configuration.ion?action=setparams <?xml version="1.0" encoding="utf-8" ?> <configuration.ion> <setparams> <component name="displayoutput_1"> <attributes> <attribute name="selectedview">1</attribute> </attributes> </component> </setparams> </configuration.ion> I'm using library HTTP_AC500. I'm successful sending HTTP. But don't know how to send HTTP/XML. I tried without success: 'http://admin:Admin123@192.168.150.132/services/configuration.ion?action=setparams/xml/?displayoutput_1=1&selectedview=2';...
