Hi,

Please, create own thread. Data what you are sending in AARQ message is correct. Server and client addresses are also correct. Reply from meter is strange. If you read your meter again is reply same?

BR,

Yes, reply is same. I tryed alse DLMS.net example - console aplication with exactly same result

I use TCP connection with one meter on network.

I find out that when I dont close connection correctly, next time this exception is thrown. I have to open connection with another TCP client, send data to meter (7E A0 07 03 21 93 0F 01 7E), response is received OK, than I disconnect from server and Gurux is working OK again

Hi,

your attention is a very interesting. This explain data. I believe that you was reading association view before you close connection. We have to think can we improve this to GXDLMSDirector.

Thank you very much for sharing this information.

BR,

Mikko
