Hi, I am writing an application for the SPODUS protocol from the GuruxDLMSServerExample project and encountered some bug with data counter:
I have a large number of values in the generic profile line (all columns from "1.0.98.2.0.255" + 3 SPODUS values), for this reason only one row is placed in the PDU, in this case the server does not read more than one record. I tried to reduce the number of columns in a profile generic row so that 2 PDUs can fit, in this case I can read more than one record, but if the number of requested records is a multiple of the number of rows in the PDU, then the server reads the data inifinite until the end of the file (DB in my case)
I found exactly the same bugs in the original project GuruxDLMSServerExample, requesting the generic profile from the example, starting from record 999, many read attempts were made with condition:
"(*it)->GetRowBeginIndex() > (*it)->GetRowEndIndex()" and negative "count"
(condition in code https://github.com/Gurux/Gurux.DLMS.cpp/blob/671fcbf5c02c77bb7dd5113ea5…)
Hi,
Hi,
To make sure that we are talking about the same issue:
The problem is that data in one row don't fit to PDU?
How many columns do you have and what is the size of them?
This is fixed as soon as it can be repeated.

No, row of my data (68
No, row of my data (68 columns) normaly fit to PDU, but it's just one line. And in the case of one line in the PDU, the server does not try to read next line. So if PDU fit only one row, i can read only one row even if i set more, if PDU fit 2 rows, i can read number of row multiple by 2, and so on.
Also server tryes to read data to the end of file in case if rows in PDU > 2 and requested entyes multiple to rows in PDU, even when it read all the necessary lines.
In this case i deleted 2
In this case i deleted 2 columns from profile generic to fit two rows in PDU, server reads only 8 enries.
Hi,
Hi,
What is your PDU size? This works without problems in my environment.

m_MaxReceivePDUSize = 1024
m_MaxReceivePDUSize = 1024
m_MaxServerPDUSize = 1024
reply size = 136 in case 1 row to PDU
Hi, i setted m
Hi, i setted m_MaxServerPDUSize to 65535 and now i can read moar then one entry with large profile generic, but seems its not wayout.

Hi,
This can now be repeated. I'll let you know as soon as fix tests are over.
