Gurux DLMS for ANSI C

Hello, I downloaded the project in the path "https://github.com/Gurux/GuruxDLMS.c/blob/master/Keil/NUCLEO-L433xx/Gur…; to my computer. I uploaded it to my own meter. I managed to connect to the meter and communicate with it using Gurux GXDLMSDirector. However, when I set the Authentication level to High and enter the password as "Gurux" as you indicated, I get the error "Access Error : Device reports Read-Write denied". I don't understand what else I need to do. Can you help me?

Hi Kurumi,

First of all, i compiled the server code in keil environment and uploaded it to my meter. i added high authentication section to the code as you mentioned before. but i get "access error: device reports read-write denied" error every time whether i enter the password correctly or incorrectly. do you have a document explaining what i need to do? or can you direct me?

Hi Kurumi,

"https://github.com/Gurux/GuruxDLMS.c/blob/9b61800b83df8b2a804e54d9d9be7…; I created a server from scratch according to the example you gave in this link and ran it. I added encryption to this code as you mentioned. I am having the following problem. When I set the authentication to none, it connects to the meter and gets the object list in the meter. However, when I set the authentication to high and enter the password, I connect to the meter, but I get the error "GetObject failed. Unacceptable frame" when reading the object list. When I debug the server code, the problem I caught appears as "DLMS_ERROR_CODE_OUTOFMEMORY". I could not overcome this problem. Can you help me? As I asked before, do you have a clearer and more precise document for creating a meter? I am running the code, but I could not find any initial settings or similar explanation.
