DLMS/COSEM Frame

Forums
General discussion

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.

inoke_id control

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?

DLMS with LoRa communication Interface

Forums
General discussion

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?

Regards
Bhaumik

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?

Regards
Ragavan IPS
