The client example

I am fairly fresh in java in general.
I imported DLMS from github to eclipse and i dont get connection in the default state.
The client responds with
showhelp() function and thats it
The Readme file on github says that i need to set device parameters and alter the code further. But I have no clue where do i put those pieces of code for it to work.

The whole repository is already imported. But a step by step guide on how to actually get a DLSM connection from that point would be very very useful.

Any help would be appreciated. Thank you.

Hi Lukáš,

If one of DLMS parameters is wrong the meter doesn't reply. Unfortunately, parameters depend on the meter and manufacturer.

Try to set TCP/P port or serial port as a parameter and let's hope that meter is using the default parameters.

You can give TCP parameters like:
-h YOUR_METER_IP_ADDRESS - p METER_PORT

and serial port like:

-P COM1

Hi,
Thank you for letting me know. I'm sorry about the slow reply but yesterday was Finland's Independence Day and it was a public holiday.

Using the below code to write

Using the below code to write time into the Meter

val item: GXDLMSAutoAnswer =
settings.client.objects.findByLN(ObjectType.AUTO_ANSWER,"0.0.1.0.0.255" )

item.listeningWindow.add(
AbstractMap.SimpleEntry<GXDateTime, GXDateTime>(
GXDateTime(-1, -1, -1, 6, -1, -1, -1),
GXDateTime(-1, -1, -1, 8, -1, -1, -1)
)
)
val mData = settings.client.write(item, 2)
for(i in 0 until mData.size){
reader?.readDLMSPacket(mData.get(i), GXReplyData())
}

I am unable to cast GXDLMSObject to GXDLMSAutoAnswer getting the below error even though I am connected to the meter
java.lang.NullPointerException: null cannot be cast to non-null type

Please help
Thanks in Advance
