Day profile action item add error (String is not recognized as valid DateTime value)

Forums
DLMSDirector

Hello Mikko,

There is a a small bug in recent Director functionality, though I can't recognize is it a code problem or a directive trouble (#if !NET5_0_OR_GREATER || WINDOWS_UWP)

I'm working with Activity Calendar object, Passive calendar tab, Day profile tab.
While trying to add day profile action with a start time field "00:00:00", I'v got a message that string is not recongized as a valid DateTime Value.

Create gateway protocol in c

Forums
Gurux DLMS for ANSI C

Good day sir,
First of all, thank you for creating this DLMS library, it makes me able to learn and know so many things from my meter. I'm able to connect to meters using settings provided by the meter provider, and read needed values from it. Currently I'm able to read meter from EDMI, since that's what I have. I used Gurux DLMS C for that.
Now I want to learn how to create a gateway, so I can be able for example connect to multiple meter.
the connection is like this:
my windows pc -- raspberry pi -- meter 1

GXDLMS Simulator – AssociationLogicalName Not Listed

Forums
DLMSDirector

Hello everyone,

I'm working on a tool to virtualize a low-voltage TLSBT meter using the Gurux.DLMS.Net simulator. I cloned the real device using GXDLMSDirector and generated a valid XML file, which I load into my simulator using the official GXDLMSMeter.cs class.

My goal is to replicate the behavior of the real meter, where, upon connecting with ClientAddress = 1, I can see multiple GXDLMSAssociationLogicalName objects listed:

Protocol Version in AARQ Packet

Forums
Gurux DLMS for ANSI C

Could you please clarify why the bit string 100001 is used as the value for the protocol-version field in the AARQ APDU?

I have analyzed multiple AARQ exchanges across different tools and interfaces, with specific focus on how the protocol-version field is BER-encoded and interpreted.

Forums
DLMSDirector

I tried to connect E650 via RS845 port, use HDLC, low, 00000000, client address 32, serial number 95798354. After save the configuration and read from meter, it seems that DLMSDirector can read some data from meter, but maybe error make it stop. But the tree display is OK. I tried to connect and read the tree parameter, it can't work.
Can you help me fix this issue?
