Can't read activity calendar

Forums
Gurux.DLMS

I am getting an segfault when trying to use activity calendar COSEM object.

Exact place where it happens:

In converters.c obj_activityCalendarToString:

when calling obj_dayProfileToString we want to append logicalName, but logicalName somehow is NULL.

Segfault occurs not always, maybe 7/10 times.

Is it known bug?

Gurux.DLMS.Python + Iskraemeco MT831

Forums
Gurux.DLMS

Good day.
We have several Iskraemeco MT831 meters connected in series to Moxa NPort 5130 via RS-485 interface. Our goal is to read the meters using Gurux.DLMS.Python but I don't understand what should I use as client address because MT831 meters do not have a regular client's address (100.1.*) but only serial number like 35765342.

I tried to use this command "python main.py -h 192.168.209.11 -p 4001 -a Low -P 12345678 -n 35765342 -t Verbose" but got an error

Parsing push messages from Iskra AM550

Forums
Gurux.DLMS

Hello,

I have an Iskra AM550 meter from electricity provider "Romande Energie" in Switzerland. I want to read data from the meter (power and energy)

It has a P1 port and I can see 1 push message every 5 sec. Serial settings are 115200-8-N-1

I tried example "Gurux.DLMS.Push.Listener.Example.python" ...and got it working !

Now I want to figure out how to extract only the useful bytes from the push message.
In my case, 1 push message seems to be 3 hdlc frames - see complete raw data at the bottom of this post.
