32 bit indices still not working

Hi Mikko,

I still can not read the association object of my Iskra meter with DLMS.c because it is > 64k. You introduced #if defined(GX_DLMS_BYTE_BUFFER_SIZE_32) at several locations, but there are still 16 bit indices left, causing the problem to read the association object.

Examples are:

https://github.com/Gurux/GuruxDLMS.c/blob/1561c2e3cf5799d0952facf2ecdc8…

At least these are loctaions that I found, but there are possibly more places. Would you be so kind of reviewing the 16 to 32 bit indices? Thank you very much!

Best regards, Jeroen

Hi Jeroen,

Can you read the meter with GXDLMSDirector and send the log file to me by email? We can check and verify this if we have the association view.

Hi Mikko,

That is not possible, this meter uses IEC start protocol at 115200 baud, i.e. not supported by DLMS director. I read the meter with Iskra software and the association view is about 90 kB.

Best, Jeroen

Hi,

You can use 115200 with GXDLMSDirector. Select Interface to HDLCWithModeE and then select serial port. Then press the Advanced button and update the baud rate.

Hi Mikko, I am trying to read

Hi Mikko, I am trying to read the meter using DLMS director, but I can not get passed the SNRM request. This is the logging:

Any ideas why it is not working? I have two suggestions: is it possible that the baud rate change over is not correct? I recall that from my earlier experiments it should be 19200 and Gurux switches to 115200. The other suggestion is that something is wrong in the properties I set in DLMS director, because the SNRM does not match a SNRM that is working (i.e. 7E A0 08 02 23 03 93 3E 74 7E)

Your help is very much appreciated!

Best, Jeroen

Hi Jeroen,

Try to change the client address to 1. Now it's zero.
Set maximum baud rate to 19200. GXDLMSDirector is using the highest baud-rate that meter can use.

Hi Mikko,

Hi Mikko,
The client addres is 0x91 and the server address was 0x00 indeed. I set the server address to 0x01, both the logical and the physical (so the server not the client as you suggested). This also does not lead to a connection:
