Hello
running DLMS Translator at RPi4 and get this error:

Messages from a Kaifa, Austria, EVN, will be translated without errors (starts with 68FAFA6853FF000167DB084B464D65509AE04281F82000004...)
Please assist, thanks

Hi Norbert,
Hi Norbert,
Lenght of L-field is invalid. It's one and that is not true. So this is a meter issue.
68
01 //WRONG. L-Field, length field, number of user data octets

Hi,
Hi,
The problem is that the size of the payload is too high.
You can fix this if you modify GetWiredMBusData -method like this.
This is only ad hoc for your problem. When you set this you can decrypt your data to XML values. I did try with C#.
//L-field.
int len = buff.GetUInt8();
int len2 = buff.GetUInt8();
if (len == 1)
{
len2 = len = 257;
}
//L-field.
if (len2 != len ||

Hi,
Hi,
Try with this:
t = GXDLMSTranslator()
t.pduOnly = True
t.completePdu = True
t.comments = True
t.authenticationKey = t.blockCipherKey = GXByteBuffer.hexToBytes("B829C67DC9DF3D9A81068540AD4C13E1")
data = GXByteBuffer("METER_DATA")
pdu = GXByteBuffer()
msg = GXDLMSTranslatorMessage()
msg.interfaceType = InterfaceType.WIRED_MBUS
msg.message = data
while t.findNextFrame(msg, pdu):
print(t.messageToXml(data))

Hi Mikko
Hi Mikko
same error:

Hi Norbert,
Hi Norbert,
Are you using the same message as in the first topic?
I tested the code using this message and it worked without problems.
I believe that you haven't set the used interface type and the translator expects that this is a Wireless MBus message.
msg.interfaceType = InterfaceType.WIRED_MBUS

Mikko
Hi Mikko
Hi Mikko
I'm running this without compile errors, but no data for the message from the Sagemcom above.
A message from another meter, Kaifa from EVN too, will be converted successfully.
What is the different ?

Hi Mikko
Hi Mikko
want to come back to this topic, because I don't get it running. Yesterday I got another smartmeter, a Sagemcom T210-D, EVN. For example I get this:
<WiredMBus len="11" >
<TargetAddress Value="67" />
<SourceAddress Value="1" />
<PDU>
<Data="7860F474867E74AF" />
</PDU>
</WiredMBus>
Any idea, why this works for the Kaifa, but doesn't for the Sagemcom ?
Thanks, Norbert
Hi Norbert,
Hi Norbert,
There is an issue in Sagemcom meter and because of that, the client can't parse the message. and the first frame is skipped.

Ask if there is a firmware available where this is fixed. You can use the code I have shown above.
BR,
Mikko
Hi Mikko
Hi Mikko
All right! I'm in contact with EVN...
Maybe you have a link to the specification of the M-Bus message / frame ?
Thanks,
Norbert
Hi Norbert,
Hi Norbert,
M-Bus message is defined on DLMS standard. Problem is L-Field, length field, number of user data octets.¨
BR,
Mikko
Hi Mikko
Hi Mikko
the issue is accepted by EVN, thanks for your support.

Hi Norbert,
Hi Norbert,
Thank you for letting me know about this. I hope that this is solved fast and you can start to read your meter.
