Hi,
Am new to DLMS programming. i need to get Voltage (V1) from the meter using Gurux.DLMS.cpp.
In GitHub i can see GuruxDLMSClientExample, GuruxDLMSPushExample, GuruxDLMSServerExample so which project i should use and where to start. i know its a very basic question. plz guide me to start it.
Am from India

Gurux.DLMS.cpp where to start
Hi,
If you want to read your meter you should use GuruxDLMSClientExample. You need to set right parameters of the meter is not answering anything.

i tried following settings. but still i cant able to get any response. i can only see ShowHelp() function. GXDLMSDirector sample is working fine with this settings
