I am trying to read values through gurux.dlms.simulator.java according to the video on the youtube(Link: https://www.youtube.com/watch?v=4o7SG3YYaIE). However, there is an error happened. The output is showing below:

Hello everyone, I'm trying to understand the protocol of the ABNT NBR 14522 standard to read electronic meters, with the idea of using an Arduino UNO or Mega in the project. This Brazilian standard is based on IEC 65056-21. I didn't find many answers in Brazilian forums.
The meter in question has an RS-232 output, I found that it is necessary to use a module to adjust the voltage levels to those of the Arduino.

Hi,

Good morning,

I found a few links to this forum when I was searching for some information about Decoding of APDU frames and Smartmeter.

I'm fighting for 2 days now with my Sagemcom T210-d-r. I get out a APDU Frame at the application layer it seems. I also received now the Key and Auth Key from my provider. The problem is I don't get out useful data.

My question would be if someone can check my APDU and try to encrypt it if he get out some useful data.

Hello. I am working with new meter. So i tried to connect with the meter via GXDLMSDirector but got "Authentication failure" message. The manufacturer advised me to disable the invoke_id control in Director. Can you tell me is it possible to disable control of the parameter invoke_id in GXDLMSDirector?

Hi Mikko,

I want to read Instant profile data from the meter having a LoRa interface.
Due to the low power range, looks like it is not able to transfer large-size packets.

Have you ever tested a meter having a LoRa interface?

Can you please provide your input?

I donot know if it is the bug , both in c# and python when use xml to read block or action block request

is there any python xml client demo ?

i am trying to write into my meter. i want to be able to recharge my meter via obis code. how do i go about it

Dear Mikko,

could find imageUpdate function in c library. with what parameters this has to be invoked?
int imageUpdate(connection* connection, char* identification, uint16_t identificationSize, unsigned char* image, uint32_t imageSize)

connection - connection object
identification - ?
identificationSize - ?
image - assume that its binary image base pointer
imageSize - image size

what are identification and identificationSize parameters? from where to get those?
what is the purpose of those?
