Hi.

Hello,
I have a project of implementing a HHU based on embedded system, which can communicate with energy meter through optical port using Mode A or C(IEC 62056-21). Can gurux provide protocol stack for this implementation? Or how should we use gurux libraries for this project?

Thank you

Hi Mikko,

In Push notification, Is it possible that frame format can be HDLC or wrapper?

As of now, From IS15959-2 meter testing, I have seen that only the wrapper frame is received in the Push notification.

So, Can you please provide any suggestions on this.

Hi Mikko,

When I send a Invalid OBIS code from Gurux Sample client(C code ) then I ma getting segmentation fault. It happens in linux and I dont know about windows EX;

./gurux.dlms.client.bin -h localhost -p 4061 -t Info -g 0.0.49.0.0.255:1
Connecting to localhost:4061
GetAssociationView
Segmentation fault (core dumped)

This is happening when we call this(hlp_getLogicalNameToString(object->logicalName, ln)) in client and this is defined in GURUX LIBRARY.

Please let us know. I am using linux (ubuntu16.04).

Are there demo smart meters around? I mean, real smart meters, that can be accessed remotely for test purposes without having to buy, install, maintain them?

HI Mikko,

I am using the C code of gurux client which I have compiled without ant changes and trying to test with premier300 using USB converter to RJ11, RS232 but the basic communication itself not happening. Please see the below command and the meter even though it is a three phase I have connected only single Phase to the R terminal and the neutral, have not connected any load as of now.
