I am a mcu programmer. i have made an single phase meter .
It can measure rms Voltage, rms Current, active power(A+,A-,|A| with rates), reactive power, power factor, frequency and many other parameters.
i want add DLMS/COSEM to it. i like start a topic about it. and question is: where I must start?and what is the first step?
I hope we could do a complete DLMS server by GURUX library for STM32F103.
Hi,
Hi,
There is no ready example for Keil at the moment, but you can use this at the template:
https://github.com/Gurux/GuruxDLMS.c/tree/master/NordicSemiconductor/Gu…
You need only change UART read/write and you can communicate with the meter.

thank you. i will read and
thank you. i will read and check it.
Hi Mikko,
ok
Hi Mikko,
Hi Mikko,
I created a new project in Keil(mdk arm5) IDE for STM32F103C8T6 mcu. i use C language.
and then i added header files only to it(according server template for nordic mcu):
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <time.h>
#include "dlmssettings.h"
#include "date.h"
#include "variant.h"
#include "cosem.h"
#include "server.h"
#include "notify.h"
#include "gxserializer.h"
#include "gxignore.h"
and i dont have any in main() function yet.
after compile i have this error:
.\include\variant.h(189): error: #3092: anonymous unions are only supported in --gnu mode, or when enabled with #pragma anon_unions
what it say?
BR,

Hi,
Hi,
i solved it. I must activate GNU mode in Keil compiler.
and i have another problem:
and i have another problem:
../Core/Src/main.c(132): error: #20: identifier "SERIAL_NUMBER" is undefined
i see this error in :
void addLogicalDeviceName(){
char buff[17];
sprintf(buff, "GRX%.13lu", SERIAL_NUMBER);
const unsigned char ln[6] = { 0,0,42,0,0,255 };
cosem_init2((gxObject*)&ldn.base, DLMS_OBJECT_TYPE_DATA, ln);
var_addBytes(&ldn.value, (unsigned char*)buff, 16);
}
wher i can find SERIAL_NUMBER? maybe i must add here my random serial number?
Hi,
Hi,
I'm glad that you solved the first question.
Please, create a new topic if you have a new question, otherwise, it's too easy to answer the wrong question.
SERIAL_NUMBER is defined like this:
uint32_t SERIAL_NUMBER = 123456;

Mikko
thank you Mikko.
thank you Mikko.
then for new questions i must create a new topics.
ok.
Hi Mikko.
Hi Mikko.
i have new question and i created a new topic for it, but i dont get any reply for it.
then i ask my question here.
I have errors about the following functions in the kill compiler:
Undefined symbol svr_connected (referred from dlms.o).
Undefined symbol svr_disconnected (referred from dlms.o).
Undefined symbol svr_isTarget (referred from dlms.o).
1- what is problem?
2- what is usage of those functions? because they dont have any imolementation?
Is it up to the user to implement them?
Hi,
Hi,
I have answered for your question here:

Hi, user must implement these
Hi, user must implement these functions. right?
1- svr_isTarget()
2- svr_connected()
3- svr_invalidConnection()
4- svr_disconnected()
5- svr_preGet()
6- svr_postGet()
7- svr_preRead()
8- svr_preWrite()
9- svr_preAction()
10- svr_postRead()
11- svr_postWrite()
righ?
thanks
Hi,
Hi,
That is correct. You need to implement those methods.
