Hi there dear GuruX community,

I wrote a script with the python library to loop through meters which are connected via an RS485 bus to multiple electricity meters from Ensor. I was able to use the example script to read out the meter, so I went on and did some adaption to read through a bunch of meters with a loop.

First I initialize the client and the serial connection:

Hi Sir,

Could you please help us on below fail condition

Inbetween the Communication Invocation Counter is not getting incremented , and because of that comunication is failing. Below is the log where you can see

[ 167674] *ERR*(20036C38/10) CosemSecurity.cpp:536 Validate invocation counter. Source: 0; Received: 11406; Previous: 11406; Current: 11406; Result: 1;

and after that Gurux gave the same invocation Counter

[ 187945] *ERR*(20036C38/10) CosemSecurity.cpp:536 Validate invocation counter. Source: 0; Received: 11406; Previous: 11407; Current: 11407; Result: 0;

Please Check the log

Hi,
I was just wondering, how meters with SN are storing passwords and client/server addresses.

When using LN, association LN object hast multiple attributes, which can contain secret, client address and mechanism_id. So you can specify which association you want with these parameters.

Green book says, that e.g. with LLS the pasword is held by Association SN/LN object, but for SN, there is no attribute for holding this information.

So what meters with SN usually use for storing secret, client id and mechanism id?

Hi Everyone,

I am trying to use the Arduino client example, the code compiles, but readings via serial monitor prints jargons, I am on the same 9600 baudrate as set in the code. I also changed to 115200 baudrate, but still the jargons on serial. Any one facing this?

I am using the latest commit from GitHub

Hi!
I downloaded Gurux.DLMS cpp from github.
Created empty project (Qt Creator) and added all sources lib files to project. Then run building but failed.
Error: 'inet_ntop' was not declared in this scope
..\guruxlib_test\guruxlib\src\GXDLMSIp6Setup.cpp:97:13: error: 'inet_ntop' was not declared in this scope
inet_ntop(AF_INET6, &(*it), tmp, sizeof(tmp));
^~~~~~~~~
..\guruxlib_test\guruxlib\src\GXDLMSIp6Setup.cpp:97:13: note: suggested alternative: 'inet_ntoa'

Hi all,

Can anyone suggest the best way to go about using the gurux dlms and a raspberry pi with a Bluetooth based optical IR port to read a meter?

Any suggestions will be really appreciated

Hello,
I increased the MAX TX field of the UA response frame from 71bytes to 230 bytes, during SNRM frame negotiation.

However, when I request the object list, I get a response "GetObjects failed. Invalid count". See frame below,

Hi sir

can i get steps to read profile generic data in ANSI C

thanks and regards
