DLMS Server in ESP32, Register object value save and load issue.

Forums

Gurux.DLMS

Hi Kurumi,

I am trying to write data in value attribute in register object and load using Serializer_Save and Serializer_Load. But I am facing issue with writing the data. Using GXDLMSDirectore when write some data and click on WRITE button, 0 is reflecting and in ESP32 server code, reference value is not reflecting the same. Its always 0.

Inconsistent Readings Conversion Between Director and Programming Library Functions

Forums

Gurux.Net

Dear Mikko,

Related to an itron (SL7000) meter's reading, it was observed a slight inaccuracy of conversion from hex to readings from programming (C#), as opposed to displaying values from Director.

Holley DTSD545S 3-phase smart meter using Lora mesh IOT-L2S-B2M and RS-485

Forums

DLMSDirector

Hi
I am trying to get data from Holley DTSD545S 3-phase smart meter using Lora mesh wireless transmitter. To get data I used RS-485 and Gurux GXDLMSDirector. Unfortunately, I can't get data and don't know how it works. Should i use other software to get data? Do you have any advice?

Gurux DLMS for Android

In exsisting Android 2.0.15 project we are not getting support for android 7 version devices were getting an exception GXSerial registerReceiver() method.
Couldn't able to modifiy that file because its read only, but we have tried to convert "gurux.serial.android-2.0.11-sources.jar" into source code after changing source code we are not able to convert it again into .jar file. Can you please support for that. Otherwise if you have any suggestion please let us know.
