Christofer Dutz commented on PLC4X-311:
---------------------------------------
One thing just struck me:
One of the main differences between the 0.6.0 and the 0.8.0 version, is the
support of multi-item-requests in the newer version. I think I recall that TC2
doesn't support them.
Could you please check if the problem persists if you use single-item-requests?

> Key: PLC4X-311
> URL: https://issues.apache.org/jira/browse/PLC4X-311
> Project: Apache PLC4X
> Issue Type: Bug
> Components: Driver-ADS
> Affects Versions: 0.9.0
> Reporter: Łukasz Dywicki
> Priority: Major
> Labels: regresion
> Attachments: amsads-shortanswer.pcapng
>
>
> I began testing functionality which did work with ADS driver in 0.6 release.
> Part of the test was reading address {{0xf00f/0x0}} (it is elsewhere referred
> as {{SYM_UPLOADINFO2}}) which returns up to 24 bytes of data. First 4 is
> symbol count, next 4 is symbol list length. Not sure what are remaining ones.
> I made an attempt to read less than 24 bytes. All requests which query below
> 24 bytes get response which do not contain index group and offset.
> I attach PCAP which clearly indicates issue.
