Hi Kurumi,
I tried to show Compact data object (IC=62) in DLMSDirector. But only first row (list of captured objects) is displayed. I expect that values of captured objects (presented in response) will be showed on the second line, similiar as in case of profiles. What shall I do to see also the values of captured objects ?

I work as tester in IT company, and we're creating electrical things, for example modems. I want to learn a bit about protocols etc. and then I noticed here are python dlms libraries etc. But, for now, I'd want to try DLMSDirector to check some things. But, how can I connect? Our modem is not on Manufacturers list.
All I have are imei, s/n, modem's IP/PIN etc. Modem's type is SIMCOM. Would it be possible to connect to my modem using DLMSDirector any way?

Hi Mikko,

The meter seems to send me responses, after that I don't understand why the connection fails :
