Convert read data to String or JSON format

Forums
Gurux DLMS for Java

Hello,

I need to read specific Obis codes and convert their values to an JSON Object.
Server Sends Obis code and Object type like Data, Register or Profile generic.

I am reading like this:
GXDLMSRegister d = new GXDLMSRegister(obStruct.obis_code);
reader.read(d,3);
reader.read(d,2);

GXDLMSProfileGeneric d = new GXDLMSProfileGeneric(obStruct.obis_code);
reader.read(d,3);
reader.read(d,4);
reader.read(d,5);
reader.read(d,6);
reader.read(d,7);
reader.read(d,8);

CoAP transport support

Forums
Gurux DLMS for Java

Good morning Kurumi,

I would like to know if there are plans t add support for CoAP transfer protoocol in the future. It's effectively a protocol which runs ontop of UDP, provides things such as block transfer, header ptins and so forth.

Kamstrup's new e-meter's speak DLMS but only over this CoAP transfer protocol, when you connect over the Internet to them.

Parsing of push-based DLMS PDUs

Forums
Gurux DLMS for Java

Good morning Kurumi,

I wanted to know if your DLMS library for Java has the ability to parse PDUs sent in push mode. By this I mean when the meter connects to OUR server and sends a payload at a regular interval.

How would one go about this? I have been able to get a lot of stuff working in the (HES -> Meter) mode but I also require to support (potentially) the mode whereby (Meter -> HES) for push data and I have no idea where to start for such a thing.

Hi Gurux Team,

Please let me know if you any provision to ping an IPv6 from Java Gurux DLMS.
If so please share code snippet for the same.

Since we have customer requirement to get ping response from meter(GPRS) IP using Gurux DLMS instead of standalone(InetAddress) Java code.

Forums
Gurux DLMS for Java

Hi Team,

I am trying to read the voltage event from the meter using profile generic 0.0.99.98.0.255 but when I am trying to read all entries it does not give full buffer data.

To cross-verify I tried to read the meter using GXDlmsDirector but got the same result. can you please guide me on what should I do to read all the events? I had tried on two different meters on client 32 but got the same result. for your reference, I am attaching a screenshot of GXDLMSDirector
