i am interfacing Secure saral meter.
connections are correct as i am able to retrieve data from meter using DLMSdirector but when i am using code client.ino from GuruxDLMS.c-master.zip then it is not giving data.

When the code is uploaded, if i will remove tx rx pins (of meter) from arduino mega board still data is getting received at rx pin, and it is same string is receiving continously.
String received is:
7E A0 07 03 41 93 5A 64 7E

I am trying to fetch data from Secure Apex 100 using RS485 port. From that port, It is connected with Moxa and from Moxa I have connected with System. COM port is COM1.

I am executing command: python main.py -S COM1 -a Low -s 16640 -d India -t Verbose

But, It is showing below result,

Hi every one ,
this is my first time with dlms ..
I need to run a client python code for dlms
There is a meter connected to the pc via serial port on com6
When I write this command
Py main.py -S COM6

I'm trying to add gurux.serial.android but I got "Manifest merger failed : android:exported needs to be explicitly specified for <activity>. Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#ex… for details." in android studio.

Hi Mikko,

Can we write value on the Registers.
For SECURE METER PREMIER 300.
I want to know how we can write. Kindly Please suggest me.

Thanks & Regards

Hello,
Is it possible to connect multiple meters (DLMS + HDLC) via single serial port and access them with different server ids?

Hello,

I have installed Gurux directory in my VMware inside the mac machine. I have create a device from the Gurux directory and connected by the terminal. Now I want to connect that Simulator from my Xcode project in mac machine. But I am not able to connect that I got some error like :

Error
stream event NSStreamEvent(rawValue: 8)
The operation couldn’t be completed. Connection refused

So is this possible to connect the VMware simulator from the mac machine. Please help regarding this.

I am new to DLMS protocol. I want to learn DLMS with arduino stuffs.

I have downloaded DLMS c code and able to build and flash it to arduino mega2560 with arduino version1.8.16. I have not changed anything in source file (client.ino). Now I want to connect arduino to GXDLMSDirector, So I created a device with random meter and configured serial communication in GXDLMSDirector.

I am getting 0x00 on UART0 (9600 baud) and getting message as ""DATA SEND FAILED" on traces UART1 (115200 baud).

Hello,

I'm trying to connect to a meter using an optical head. The connection is closing after sending AARQ request. I'm relatively new to DLMS protocol but after spending 2 days on the problem I can't find a way forward. Could you please help me ?

Here are the logs :

Does the Python/Gurux supports gateway protocol (similarly as Gurux Dlms Director)?

Please could you point me to some documentation/specification which describes gateway protocol (some IEC spec, or DLMS spec.)?

BR,
Miroslav
