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.

Need support for Android 7 version.

Forums
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.

After ProfileGeneric data parsing an incorrect float value is returned

Forums
Gurux.DLMS

The device returns the correct value 522140, but after multiplying by scaler 0.01, returned the value 5221.40000000000005.

This does not happen with all data.

Below is a screenshot showing the code of file "GXDLMSProfileGeneric" with incorrect data conversion.

Please tell me, can this be fixed?

Thanks.
