I have successfully received SNRM and ARQ. When i try to read clock object receiving the wrong frame which i found it as error frame. I am trying to use as below
reader= GXDLMSReader(settings.client, settings.media, settings.trace, settings.invocationCounter)
reader.initializeConnection()
d =GXDLMSClock("0.0.1.0.0.255")
reader.read(d, 8)

the output frame for clock is

TX: 12:55:37 7E A0 19 03 21 32 6F D8 E6 E6 00 C0 01 C1 00 08 00 00 01 00 00 FF 08 00 10 E7 7E 8
RX: 12:55:42 7E A0 0C 21 03 97 3E 21 10 22 08 29 D6 7E 8

Hi,

HDLC frame error doesn't tell anything. Can you read the clock object with GXDLMSDirector? I can't solve this without all the frames.

Hi, the only way I get this works is by using getAssociationView(), all data is saved in a file and get the value using obis code (voltage = 1.1.32.7.0.255).
Is there another way to get data by using obis code without using getAssociationView and a file?

Hi Reese,

Please, create a new topic if you have a new question. You can also create objects to the code if you don't want to use the file.
