Hi,
I am running sample client with smartmeter via HDLC. In case of LLS authentication, I am getting the below error,
Jul 14, 2022 2:38:00 PM gurux.dlms.GXDLMSSettings checkFrame
INFO: Invalid HDLC Frame: 42 Expected: 52

How to resolve this?

Regards
Pooja

When I read clock from device, that device provided datetime
According to device manufacture, there is problem in deviation data among
datetime data.
They recommended to ignore deviation data.
Without deviation data, datetime is correct.
So I want to know how to ignore deviation data to calculate date and time.
The below is response data from device which had wrong deviation data.
07E6. 06 1E 04 0D 2D 1B FF FDD2 95
2022 06 30 13 45 27
I found code convert response to date and time format in GXDLMSClient.class

hi, what datetime should i pass to method ReadRowsByRange to read just one hour?

Hi,

I sent notification through sendPush() method on server example.
It works perfectly, but it seems to be weird when Profilegeneric object included.
It couldn't be translated with Gurux DLMS Translator on GXDLMSDirector.

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.

Hello,
I have setup the Java server example in Maven on my Raspberry Pi. When i connect and associate in DLMS Director, i cannot see the example register value in it (picture included). When I add the dependency in my POM file i cannot compile it at all.
How do i show the value?
Thanks for the answer.
Best regards,

Hi Mikko,

We can change byte[] date to GXDateTime using GXDLMSClient.changeType for certain OBIS Ids like(0.0.0.1.2.255)
Ex.
GXDLMSClient.changeType((byte[]) dt, DataType.DATETIME)

But How to do reverse? If I have to change a GXDateTime Object to 12 byte size byte[].

We need this for passive relay time, 4th parameter OctetString.

Hi Mikko,

For firmware upgrade, I had followed the steps under Image Updating section of DLMS client (Thanks for steps) and that is working fine.

Now I want to support resume functionality, if any firmware block fails during the image transfer.
But, I did not see any attribute or method to resume the block transfer.

Please help me with steps for firmware resume.

Thanks in Advance.
