Acknowledgement of KNX group telegrams
#2
Hi
The situation described above by KNXUser is a serious design issue. I've reported it few years ago and it looks there's still no solution at all. I think his idea with limiting ACKs is great.

Today I found new strange behavior of ACKing:
I've two LMs connected to the same line. The first one has "ACK All group telegram" turned on. The second one (backup) has it turned off.
My first LM (Version: 20180822) shows 4 repeats per hour
My backup LM shows (Version: 20211014) shows 4000 repeats per hour.
If I turn "ACK All group telegram" on at the backup LM then this counter drops significantly down.
It seems to me that internal changes require ACKing too.
LM5Lp, firmware: 2018.08.22 and 2021.12.15, FlashSYS v2, ARMv7 Processor rev 5 (v7l), kernel 4.4.151 and 4.4.259
