GetRequestWithList Translator error

Hello Mikko,

there is a bug in Gurux DLMS Translator while processing GetRequestWithList

sample data exchange:

TX: 08:26:48 7E A0 39 02 23 61 76 ED 4D E6 E6 00 C0 03 C1 04 00 03 01 00 00 06 00 FF 02 00 00 03 01 00 00 06 01 FF 02 00 00 03 01 00 00 06 02 FF 02 00 00 03 01 00 00 06 03 FF 02 00 A7 4F 7E

incorrect translation:

<HDLC len="20" >
<TargetAddress Value="30" />
<!-- Logical address:1, Physical address:17 -->
<SourceAddress Value="91" />

<GetResponseWithList>

<Result Qty="04" >
<Data>

</Data>
</Result>
</GetResponseWithList>
</GetResponse>

</HDLC>

correct translation :
(after modifying
static void HandleGetResponseWithList
where in the cycle end
reply.Data.Position= reply.ReadPosition;
should be
reply.ReadPosition=reply.Data.Position ;)

Hi Andrew, I believe that…

Hi Andrew,

I believe that you are right, but this needs a little more investigation.

I'll keep you posted.

BR,
Mikko
