Gurux.DLMS

Hello
I have successfully made a dlms server using your GuruxDLMS.c arduino code on mega2560. Fortunately, HighGMAC is presented in your recent arduino release but unfortunately, the Invocation Counter object presented in this code returns no data so I cannot connect to the MDM or GuruxDLMSDirector with automatic read option of this counter. Would you please help me fix this problem?

Sincerely Yours

Hi,

HighGMAC doesn't require invocation counter reading. Change authentication for HighGMAC and set client address to 1 and you can connect for the meter.

I tested this with settings:
-S COM3 -c 1 -a HighGMAC -P Gurux -t Verbose

BR,

Thanks dear Mikko. Yes, that works, but unfortunately I am currently working on a project which has a mdm sever which reads invocation counter and when I make general examples on PC, the invocation counter is present and working, but in arduion code example, the Invocation counter is presented but does not work and returns no data, How can I make such improvement in the arduino code to make it functioning as well as PC code examples? Is there anything missing in the arduino code in comparison with the examples?

Sincerely yours
