#13 Unable to auto discover Merit Lilin IPS-1254P

[Jason Williams]

Hi,
I am trying to use the software to communicate with the above camera, however it doesn't seem to appear in the list of discovered devices ;-(. I have done a wireshark trace, and I can see ws-discovery packets coming from the device, but I am not sure whether these are valid or not. Please advise.

Hi. Thanks for the quick response, I have emailed you the traces and logs, please let me know if you need any more info.

Hi,
I analyzed logs that you sent, the first problem I found is that ws-discovery "hello" have incorrect header "To", according to the specification http://specs.xmlsoap.org/ws/2005/04/discovery/ws-discovery.pdf (page 14) it should be "urn:schemas-xmlsoap-org:ws:2005:04:discovery" instead of "http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous". Anyway we can make some workaround to fix it. Problem in ws-discovery "ProbeMatch" is much worse, here element /Envelope/Body/ProbeMatches/ProbeMatch/Scopes contains illegal char (0x01), it causes the deserialization failure, and I have some doubts about how to fix it, but I will investigate the possible ways how to fix it.

Excellent, or maybe not so ecxcellent :-(. Are you happy for me to go back to the manufacturer with your findings so that they can also address the issue at their end?

[Andrey Vrana]

Sure. You can give our findings, also if you need, You can use our sources from Sourceforge SVN.
