we are using android library. library works with non ciphered meter whereas with ciphered meter we are not getting response for assocation request. please correct the flow if we are doing mistake. attached tx and rx log along with code snippet.
We are trying to download profilegeneric data from meter using ANSI C library. At point DLMS stack is getting struck at getCount function . Attached Tx and Rx log also the function call history.
For your information , meter is working with GuruxDLMSExplorer
Tx : 7E A0 07 03 41 93 5A 64 7E
Rx : 7E A0 20 41 03 73 3E 9D 81 80 14 05 02 02 26 06 02 00 9B 07 04 00 00 00 01 08 04 00 00 00 01 B6 DC 7E
Hope you are safe and doing good. Clarification is required regarding ANSI C library for microcontroller client side.
gxProfileGeneric prfileGen;
if we call com_readRowsByEntry(&prfileGen,....) or com_readRowsByRange(&prfileGen,....) multiple times with different parameters like(large from and to date or more rows) then for the consecutive calls memory will be deallocated and allocated newly or how is it?
How do we free prfileGen object so that memory can be used for someother purpose
Hi Mikko,
As Per Indian standard documents they saying that we can able to change Low association password through High association by using LLS_Secret Attribute.
Association LN Object has two options for SECRET change :
1. LLS secret is changed by writing attribute 7 (for, low association password change)
2. HLS secret is changed by method 2 (High association password change)
In Gurux Library and GDLMSdirector that attribute not available.
Please help me how can I Solve this.
We are using the Atmel code from the Gurux C stack and attempting to implement client-side solution for reading from a meter using Atmega2560 (Arduino Mega 2560).
However, the code is not getting compile. (Build errors).
It gives compile time errors saying that the following header files are missing:
same70q20.h: No such file or directory
sam.h: No such file or directory
Can you explain more about DLMS flow, I do not understand much about its Flow.
differentiation help me DLMS and DLMS/COSEM.
I searched a lot of documentation but couldn't see how DLMS transmits the packets (Flow)
We downloaded the latest release covering the special day table and we started the testing.
- We added today as a special day in order to be able to test :
index = 0 special day date = 1/1 dayID = 3
index = 1 special day date = 6/3/2021 dayID = 3
index = 2 special day date = 12/21/2020 dayID = 2
