Hi,

The function com_getAssociationView is supposed to read from the file if it exists, else read from meter and save to file. But it is not saving to the file even though 58 objects were read from the meter. Upon inspecting I found that CURRENT_ASSOCIATION[0] is null. Please let me know how to save to the file.

Sample code:
int ret = com_open(&con, port);

hi, when I'm reading GXDLMSLimiter object, it's MonitoredValue attribute does not bind and returns null.
I checked packets and it contains data correctly.

7E A0 1C 00 02 76 71 03 32 98 1F E6 E6 00 C0 01 C1 00 47 00 00 11 00 00 FF 02 00 9B 28 7E
7E A0 22 03 00 02 76 71 52 D8 51 E6 E7 00 C4 01 C1 00 02 03 12 00 03 09 06 01 00 16 07 00 FF 0F 02 87 51 7E

meter returns UnacceptableFrame frame when reading with List.
do you have any idea about this ?

Hi!

Can you give me some example of authorization.
- How can I add a new user.
- How can I set access to a register, cuz I tried to do like this:
RegPointer->SetAccess(2, DLMS_ACCESS_MODE_AUTHENTICATED_READ);
But it still was available even without authorization.

Hi sir.. Im running -t Verbose and getting the hex trace as follows im getting the following error.. Pls help

Hi,
I created a project in Keil compiler for STM32f103. i added all source and include libraries.
but when i start compile i have below errors:

Hello. I am developing a function in .NET for an Iskra MT880 meter. I have already initialized the communication with the meter and I would like to know how to obtain the data of load profile 1. Currently I have the code like this but it throws an error: "Capture objects not read"

I'm new to DLMS/COSEM and I can't understand it very well. I appreciate your help in solving the problem.

*** already solved ***

When using the Wrapper interface, EOP is null. In that case, if there is a timeout, the __findData method should return a -1 value.
The problem is that at the end of the method (line 232 in _GXSynchronousMediaBase) the if nSize == 0 is always true so foundPosition value is overwritten and results in an infinite loop.
I don't know how to solve it.

Thanks

Hi Mikko,

I am trying to upgrade meter firmware but am stuck with the block size issue.

Here is the simple code, which was in another topic:

tr = GXDLMSImageTransfer
imageBlockValue = # Read this from the file.
frames = tr.imageBlockTransfer(client, imageBlockValue, None)

So, the question is how to read imageBlockValue from the file. I check description details in Blue Book but it is still not clear how to do it in Python library.

It could be nice to have a Python example for the firmware upgrade.

Thank you,
Ilya

i am using the python example and getting the following

[Trace removed.]

No i have figured how to use python3 main.py -S /dev/ttyUSB0 -t Verbose -r sn -g "1.1.1.8.1.255:2" to get the value now i am not sure which object i should select to get the current meter energy reading displayed
