Parsing notification body.

Hi,
I'd like to parse notification body.

I sent notification through sendPush() method on server example.
When I added some empty objects on GXDLMSPushSetup, it worked perfectlry.
It can be also translated with Gurux DLMS Translator on GXDLMSDirector.

However, when I added profile generic object (ln : 1.0.99.1.0.255), it didn't seems to be translated notification body.

It shows like this :
BlockCipher key: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
Authentication Key:D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 DA DB DC DD DE DF

<HDLC len="56" >
<TargetAddress Value="40" />
<SourceAddress Value="1" />

<FrameType Value="13" />
<PDU>
<DataNotification>



<LongInvokeIdAndPriority Value="C0000003" />

<DateTime Value="" />
<NotificationBody>
<DataValue>
<Array Qty="00" >
</Array>
</DataValue>
</NotificationBody>
</DataNotification>
</PDU>
</HDLC>

Please let me know how to parse it.

Thanks in Advance.

Hi,

It seems that there is an invalid byte in the data. Are you using malloc in GXDLMSPushSetup or is this the original example where you have added the profile generic object?

BR,
Mikko

Thanks for your kindness.

I added two objects for the notification test, at last of init() method in GXDLMSBase.java.
(using example codes on github.)

1. I added a new GXDLMSProfileGeneric object and add rows like this :

GXDLMSProfileGeneric pg = new GXDLMSProfileGeneric("1.0.99.1.0.255");
pg.addCaptureObject(new GXDLMSData("1.0.128.0.11.255"), 2, 0);
pg.addCaptureObject(new GXDLMSRegister("1.1.1.8.0.255"), 2, 0);
pg.addCaptureObject(new GXDLMSRegister("1.1.5.8.0.255"), 2, 0);
pg.addCaptureObject(new GXDLMSRegister("1.1.8.8.0.255"), 2, 0);
pg.addCaptureObject(new GXDLMSRegister("1.1.9.8.0.255"), 2, 0);
pg.addCaptureObject(new GXDLMSClock("0.0.1.0.0.255"), 2, 0);
pg.addCaptureObject(new GXDLMSData("0.0.97.97.4.255"), 2, 0);
pg.addRow(new Object[]{2992, 4351, 67, 2096, 8781, new GXDateTime("2022-05-23 12:00:00"), "000011000000000000000000"});
getItems().add(pg);

2. And I added a new GXDLMSPushSetup object like this :

GXDLMSPushSetup push = new GXDLMSPushSetup("0.2.25.9.0.255");
push.setDestination("127.0.0.1:4059");
push.getPushObjectList().add(new GXSimpleEntry<GXDLMSObject, GXDLMSCaptureObject>(push, new GXDLMSCaptureObject(2, 0)));
push.getPushObjectList().add(new GXSimpleEntry<GXDLMSObject, GXDLMSCaptureObject>(pg, new GXDLMSCaptureObject(2, 0)));
getItems().add(push);

3. Finally, I called sendPush() method using push object.

I don't know why exist invalid byte in the data.

Please let me know If I had something wrong.

Thanks in advance.
