Hi,

I am trying to update the meter firmware using GuruxDLMS.c library. I am able to establish connection with the meter in Firmware Upgrade mode. Post this, while i am trying to read Image transfer enable status, block size and image transferred block status, meter isn't responding for the one of the TX sent by stack and stack is hanging in com_read function while returning with DLMS_ERROR_CODE_RECEIVE_FAILED error.

Request you let me know what could be the reason.

Please find below details for your analysis.

Hi Mikko, i am back working on the itron meter data reading. I created new forum post because i can't reply on the old one. 
After trying out the update, the issue on reading Itron SL7000's load profile (0.0.99.1.0.255) still persists
- if i read capture objects first (index 3), it returns error 13 : DLMS_ERROR_CODE_ACCESS_VIOLATED
- if i read without it, it returns error 258 : DLMS_ERROR_CODE_INVALID_PARAMETER, but i can see some data in the traces, and i can use GXDLMSTranslator to translate and get the data

Hi Mikko,

I have to write the following array in the meter.

<Array Qty="01">
<Array Qty="02">
<Structure Qty="02">
<OctetString Value="070000FF"/>
<OctetString Value="060000FF"/>
</Structure>
<Structure Qty="02">
<OctetString Value="080000FF"/>
<OctetString Value="090000FF"/>
</Structure>
</Array >
</Array>

Hello Mikko,

What should I do to get method call result?
For example, object target is of GXDLMSImageTransfer type.

Let's use method 3 "image verify".
As written in BlueBook "The result of the invocation of this method may be success, temporary_failure or other_reason."

Following code works ok:
reader.readDataBlock( target.imageVerify(reader.client), reply)
How should I check that result is success, temporay failure or something else?

Is it reply.error values according to green book or something else?

Hello Sir,
I am using below dependency in my Android project. But when I ran my project with minSDK version 29 its gives error so, to using those I need to maintain my minSDK version 31. Is it possible to run in 29?

releaseImplementation(libs.guruxDlmsAndroid)
implementation(libs.gurux.serial.android)
implementation "org.gurux:gurux.common.android:3.0.4"

Hi

Did you remove all releases of GXDLMSDirector?
I cant find any download

Hi everyone,

I’m trying to interface a Schneider Electric / L&T DLMS Category C3 bi-directional energy meter using its RS232 port, which is exposed using an RJ11 4-pin connector. I’m stuck at a few points and would really appreciate guidance.

1. RJ11 RS232 Pinout (4-pin) for L&T / Schneider meter

The meter manual is not clear on the RS232 pinout.
Does anyone know the exact mapping for:

Pin 1 – ?

Pin 2 – ?

Pin 3 – ? (ground?)

Pin 4 – ?

A confirmed TX, RX, GND assignment would help a lot.

2. No voltage on pins?

Hello Mikko,

there is a bug in Gurux DLMS Translator while processing GetRequestWithList
