I found GuruxDlmsSample has missed out the parameter -n for Meter Serial number, anyone has idea how to add in the command for parameter -n ?

Hello,

I'm trying to read data from a DLMS device using your sample code and i get the error that appears in the attached image.

Could someone give me a clue on how to solve this problem?

Thanks in advance,
Carlos

I have downloaded gurux.dlms.client and uploaded to my Eclipse, however when i try to run the sampleclient.java, it seem not work very well.

Refer to the command line,
if I run GuruxDlmsSample -r SN -c 16 -s 1 -sp COM3 -i
error: Invalid reference option

Found SN should be small cap, then i change to
GuruxDlmsSample -r sn -c 16 -s 1 -sp COM3 -i
error: "For input string: "COM3".

Hi Mikko,
I am reading new type of L&T meter by setting BlockCipher ,AuthenticationKey
and Frame Counter LN. Its working in GXDLMSDirector.(Please check the
