Forums
Gurux.DLMS

Greetings!

I am referring https://github.com/Gurux/GuruxDLMS.c/tree/master/GuruxDLMSSimpleServerE… example. I have generated project in STM32CubeIDE from the given MX file (with extension .ioc). Now, I am unable to find a file. 'gxbytebuffer.h' for ANSI C. I have gone through all the folders this project contains and searched on GitHub.com as well.

Care to help!

Thank you.

Kind regards,

Regarding security suite v2 support in gurux.dlms.c

Forums
Gurux.DLMS

We are evaluating to use GuruX DLMS server in C in our product.
Please let us know whether gurux.dlms.c supports Security Suites v2?

In the source code, it shows support for DLMS_SECURITY_SUITE_V2.

/*
AES-GCM-256 authenticated encryption, ECDSA P-384 digital signature, ECDH P-384 key agreement, SHA-384 hash, V.44 compression and AES-256 key wrap
*/
DLMS_SECURITY_SUITE_V2 = 2

While DLMS_SECURITY_SUITE_V2 is used only in AES-GCM-256 function, need to know whether ECDH P-384 key agreement support is also available?

ciphered action request

Forums
Gurux.DLMS

I have question related to ciphered connections. Does CGXDLSClient class functions like Method or Write automatically use global versions of messages for example DLMS_COMMAND_GLO_METHOD_REQUEST instead of DLMS_COMMAND_METHOD_REQUEST and DLMS_COMMAND_GLO_SET_REQUEST instead of DLMS_COMMAND_SET_REQUEST ? Or we need to call another functions maybe some low-level ? Or is change in C++ Gurux library needed to use this messages in our application ?
