I am using the NXP AN12837SW reference design for my smart metering project with the MKM35Z512VLL7 controller. Now I want to transfer/send my .bin file to uart terminal through serial wire(not in gsm) for firmware upgrade.
Could you please clarify the following points:
1. How to load the (.bin) file in Gurux, How to divide it into 256-byte chunks and How to add CRC/AES Encryption data for transmission?
2. What is protocol/documentation available for image transfer?
3. Can we send the firmware without OBIS code through uart?

Hi,

I am trying to receive load profile push from meter that uses GNT block transfer. Following are the received messages, in notification and also in translator i am unable to see complete PDU decrypted data. I am not sure if Director/Translator is unable to create complete PDU or if there is some issue with push message. Requesting your help on the same.

Hello,
I'm trying to use DLMSDirector to discover what is available on the meters ACE6000 and SL7000. It's my first time trying DLMS protocol.

I manage to successfully connect to the meter, and get the serial number / manufacturer name.

HDLC, logical name referencing

Client address : 1
Auth : Low
Password : ABCDEFGH
Logical server : 1
Physical server : 17 (or 0x11) - works as well with 0x3FFF
Media : Net
IP, Host, checked Use serial port throught Ethernet.

I am trying use the simulator to perform load testing on 1 Million meters with same replication as meter does, like secrets, ciphering etc., So I tried to modify crystal.xml but there is little understanding gap I want to fullfill.

Need crystal.xml using which Profile Generics read can be perfomed. I am able to create xml file with HIGH association but can you please provide me xml using which I can read all profile generics with all type of associations.

Below is the file which I have created with refence to the already created one:
[XML removed]

Hi,
I want to retrieve data from two Holley DTSD545 smart meters using a single RS-485 communication port. I can read data from the first meter, but when I try to add the second meter, it can't connect.

Good afternoon Kurumi,

I'm trying to connect to Hexing HXE115-KP with Gurux GXDLMSDirector Version 9.0.2506.2601.

The IEC62056-21 protocol handshake is executed successfully.

I have a doubt about the scalar part in the profile generic class. In the block load profile, for the voltage parameter, there is no decimal point displayed in the UI. As I have given the scalar part in the Scalar: block load profile parameter.

Hello Mikko,

Current Association - > General tab ->Update High password results to new password sent in non-ciphered way.

Is there any way to cipher password to be set?

Hello Mikko,

How should I fill in 'day of week' value in Daylight savings begin/end fields, clock object?

As written in blue book "4.1.6.1 date and time formats examples":

"2) year = 0xFFFF, month =0x FF, dayOfMonth = 0xFE, dayofWeek = 0x07: last Sunday in every year and month;"

so where should I use "7" value in that field?

Best regards, Andrew

I have made a configuration on "Register Activation" class but attribute index data 3 is not visible on GxDLMS Director. Instead of data it is showing following system Generic list as

 System.Collections.Generic.List'1[System.Collections.Generic.
KeyValue2[System.Byte[].System.Byte[]]]

 System.Collections.Generic.List'1[System.Collections.Generic.
KeyValue2[System.Byte[].System.Byte[]]] 

Tariff log of all attribute index are (rest attribute index data is visible on GxDLMSDirector screen) as 1
