I have made the connection settings as below using python. I can read the objects when the auth is low and client address is 32. But i am having issue with high authentication.
Note: I have purposefully did not add passwords here.
if ser.isOpen():
print('if - 1')
settings.client.ciphering.security= Security.AUTHENTICATION_ENCRYPTION
settings.client.ciphering.invocationCounter = 1000
settings.client.useLogicalNameReferencing = True

GetRequestWithList fails in Gurux.DLMS.cpp with "segmentation fault" if some requested objects not in collection of AssociationView.
Here is the crash log:

Hello I would have a question because I can't seem to find an answer.
So the Gurux- DLMS library prints the result like this:
TX: 07:00:11 00 01 00 01 00 01 00 38 60 36 A1 09 06 07 60 85 74 05 08 01 01 8A 02 07 80 8B 07 60 85 74 05 08 02 01 AC 0A 80 08 31 32 33 34 35 36 37 38 BE 10 04 0E 01 00 00 00 06 5F 1F 04 00 00 1E 5D FF FF

Is it possible to convert datetime to hex string? I am using python. For example:

client = GXDLMSClient()
hex_str = "07E705180300000000800000"
dt = client.changeType(hex_str, DataType.DATETIME)
print(dt)

result: 05/24/23 00:00:00:000000

Now I want to convert from 05/24/23 00:00:00:000000 to 07E705180300000000800000.

Is it possible?

Hello, i am trying to read association logical name object but i get Not enough memory available error.

I am trying to do as your client example says to read one bye one, but i never leave com_readDataBlock() method and com_readDataBlock() returns out of memory error. Should I read only one data block, parse it, then again read?

I have successfully received SNRM and ARQ. When i try to read clock object receiving the wrong frame which i found it as error frame. I am trying to use as below
reader= GXDLMSReader(settings.client, settings.media, settings.trace, settings.invocationCounter)
reader.initializeConnection()
d =GXDLMSClock("0.0.1.0.0.255")
reader.read(d, 8)

the output frame for clock is
