Dear,
We have a problem while reading the meter if the meter is using GBT. When we try to read large data(ex: profile generic buffer) the meter uses GBT and communication used to time out. On further investigation, we have found out that Gurux is using get next block of the get service rather than acknowledging the received GBT message.
Bellow is the sequence of messages:
Ger request normal(00 01 00 01 00 01 00 20 C0 01 C1 00 07 01 00 63 01 00 FF 02 01 02 02 04 06 00 00 00 01 06 00 00 00 32 12 00 01 12 00 00)

Get next block:(00 01 00 01 00 01 00 07 C0 02 C1 00 00 00 01).
I have also added the GeneralBlockTransfer and GeneralProtection to proposed conformance and the meter accepts the conformance.
Could you please let me know how can we use GBT in this scenario or is there any option to for use of GBT for all scenarios.
Thank You

Hi,
Hi,
I need to verify that you are using Java version? Have you tried with GXDLMSDirector?

Hi Miko,
Hi Miko,
We are using
Java 1.8
Gurux dlms 2.2.26
When I try reading with GXDlms director, It can read other attributes as they are small enough to fit in a single window but fails while reading attribute 2(buffer).
Thank You

Hi,
Hi,
Java Client support for GBT is now added and the new version is on GitHub.
It's tested a couple of days and we'll release a new version next week.
Streaming is not supported at the moment. Only Window size one is supported at the moment.

Mikko
Thanks for the update Mikko,
Thanks for the update Mikko, I will check out the code from GitHub and give you feedback.
We have tested and GBT works
We have tested and GBT works and also streaming works if the window size is set to more than 1.

Thanks.

May I know why would you need
May I know why would you need this. The problem i had has been solved and i no longer have the test setup. It would take me couple of hours of effort to get these logs.
