Forums
Gurux DLMS for Android

Hello Gurux Team and Community,

I'm writing to share an issue I encountered with the official Gurux.DLMS.Android example project from GitHub when running it on newer versions of Android.

The Problem
The application works perfectly on a device running Android 12 (API 31). However, when I try to run the same project on a device with Android 15 (API 35), the app is not working at all.

Connect to ISKRA meter

Forums
Gurux.Net

Hello,

I was able to connect to an ISKRA MT880 meter via GXDLMSDirector with parameters: -h 172.18.54.201 -p 4002 -c 1 -s 164 -a Low -P 12345678 -d Italy -w 1 -f 154 -t Verbose

If I try with C# code I am not able to connect. What am I missing?
Thanks
