Gurux DLMS for Java

Hi,

I ran the dlms simulator with parameters using command :
java -jar target/gurux.dlms.simulator.java-0.0.1-SNAPSHOT.jar -p -x crystal.xml -t Verbose -N 2 -X

when N = 2 i'm able to read data from DLMS client example in gurux's github repo using command :
java -jar .\target\gurux.dlms.client.example.java-0.0.1-SNAPSHOT.jar -h 10.0.8.8
-p 9654 -t Verbose -n 1

problem arises when i use N =3 or more in simulator command, after running simulator if i use the same client command, then i get invalid tag error.

Below is the error stack trace :

java.lang.IllegalArgumentException: Invalid tag.
