Hi, Kevin,

 

Thanks for the quick reply. Here is the response from the server captured by Wireshark. Seems like, as you mentioned it, it is returning a bunch of extra characters, this was tested both in a real and a simulated SIMOTION, obtaining the same results.

I do wonder if it's as simple as UaExpert deciding to stop displaying after the first null 0x00 byte it encounters, though. It certainly looks like this server is just returning a bunch of extra crap in the String value.

That's pretty strange.

 

Can you get a Wireshark capture that contains the Read request/response? You'll have to connect without encryption for the capture to be usable.

 

I'm going to be gone and without phone or internet service for a few days so I likely won't be able to look at this right away.

Hi everybody,

 

I’m having some issues when reading a variable from a SIMOTION device, it’s a String that can be correctly read using UaExpert:

 

However, when I read it using milo I get a byte array with 510 positions that contains the original value, but also some random bytes that cause the String to come with some wrong ASCII values:

 

What could be the cause of it? It happens only with the factory set values of the SIMOTION, with custom ones I have no issue at all.

 

Thank you in advance for your help and support.

 

Daniel Moreno
