Hello,
I'm trying for past few days to use keyAgreement method from SecuritySetup to agree on keys on multiple meters from different vendors.

So far all my attempts resulted in error: Other reason.

Hi Team,

I am working on implementing RF communication for smart meters and need some guidance on the following:

What are the initial steps required to establish RF communication with a meter (hardware setup, protocol, initialization process)?

What are the key variables/parameters that are transmitted during RF communication (e.g., addressing, payload structure, control fields)?

Any documentation or reference would be helpful.

Thanks.

Hello everyone. Has Gurux implemented the data-notification-confirm mechanism? If it has been implemented, could you please share how it is handled in the code?

I have successfully established the Bluetooth connection and completed both the SNRM and AARQ stages. However, during the Association View phase, I'm facing an issue where the full HDLC response is not being received consistently. Despite requesting the maximum MTU size of 517, the response often gets truncated.

For example, sometimes the Association View responses complete up to the 9th continuation request, while at other times, it stops at the 3rd or 4th request, resulting in an incomplete frame and a parsing failure.

Hello,

I’m working on a Java project using the Gurux DLMS library to certify DLMS/COSEM communication with the IM300 meter from WASION.
I’ve managed to establish the physical connection to the meter (via serial/TCP), but I’m facing issues during the authentication process. Specifically, I’m encountering errors in the second step of the communication, during the AARQ request (Application Association Request), where the meter should reply with an AARE (Association Response).

Below are the authentication parameters provided by the manufacturer to assist with configuration:

Hi, I managed to create working java code (I mean, without java-related errors, underlining and highlighting), but anything I do ends with "ServiceError Initiate Error exception. Service UNSUPPORTED" error. I tried to use same settings as I used in GXDLMS Director app - I managed to make successful connection from here and read some data with lowest Access level (Public association, without auth or encryption, no keys etc.), cmd line for it looked like that:

Hi there,

I have tried the GuruxDlmsPushListenerExample.
When my smart meter mock send a message to the client I have got this on the console:
 

Getting error like this,
