Dear,
We have a problem while reading the meter if the meter is using GBT. When we try to read large data(ex: profile generic buffer) the meter uses GBT and communication used to time out. On further investigation, we have found out that Gurux is using get next block of the get service rather than acknowledging the received GBT message.

Bellow is the sequence of messages:
Ger request normal(00 01 00 01 00 01 00 20 C0 01 C1 00 07 01 00 63 01 00 FF 02 01 02 02 04 06 00 00 00 01 06 00 00 00 32 12 00 01 12 00 00)

Hi,
I'm making client in java and I got exception while reading time. LN name is 0.0.1.0.0.255 and atribute 2.
Request:
000100110001000dc001c100080000010000ff0200
Response:
0001000100110012c401c100090c07e3050f030d082bff008080

We are not getting any values out of the reply when using get with list and if the response is more than one data block. We have the below code to read with list:
01private void readList(List<Entry<GXDLMSObject, Integer>> list) throws Exception {
02 if (list.size() != 0) {
03 // uses Command.GET_REQUEST with GetCommandType.WITH_LIST
04 byte[][] data = client.readList(list);
05 GXReplyData reply = new GXReplyData();
06 List<Object> values = new ArrayList<Object>(list.size());

I am using org.gurux:gurux.dlms:2.2.24 and I found that calendar_name_passive/calendar_name_active(gurux.dlms.objects.GXDLMSActivityCalendar) has not the same format than my COSEM Blue Book 12Th edition.

In the COSEM Blue Book 12th edition I have this format :

calendar_name_active ::= octet-string
calendar_name_passive ::= octet-string

In the java class GXDLMSActivityCalendar I have this format :
calendar_name_active ::= visible-string
calendar_name_passive ::= visible-string

Hey there, I'm trying to read Import Active maximum demand from my smart meter but unfortunately, it gives me the error bytes. My smart meter model is DTSD545 and company manufacturer is Holley Metering System.

First, I read the Maximum Demand from Gurux Director. I attach the screenshot. It successfully gives me the value of demand but when I try to read the maximum demand from my program it gives me an error. The following how I try to read value.

When using the function GXDLMSClient.write(GXDLMSObject, attributeIndex) to write some data to either DLMS Class id 1 or 3 fails for some data types.

Hi ,
I am new to this. while trying to connect to meter using following command
java -jar ......jar -h [IP] -p [port] -a None -c 16 -s 1

Reading GXDLMSClock 0.0.1.0.0.255 invalid.

Kindly help me out to resolve.
