Hii Mikko,

Now, i am able to communicating meter with python SDK. SO after initializeConnection is there any feature in your SDK like whatever the OBIS code if we give from command line meter should responds to that particualr OBIS code.
Because here SDK is reading all parameters. So can you please help regarding this as soon as possible.

Hello Mikko

In GXDLMSReader.py i included below piece of code that i got it from one of your forum.

def readAll(self, outputFile):
try:
read = False
self.initializeConnection()

# OBIS Clock
d = GXDLMSRegister("1.0.32.7.0.255")
self.read(d, 2)

self.getReadOut()
self.getProfileGenerics()

if outputFile:
self.client.objects.save(outputFile)

except (KeyboardInterrupt, SystemExit):
self.media = None
raise
finally:
self.close()

and in main.py i modified like below

settings.media.open()
reader.initializeConnection()
reader.readAll(settings.outputFile) -------- directly i am calling this then i am getting below logs

Hii Mikko,

I am receiving below packet
[[<gurux_dlms.GXDateTime.GXDateTime object at 0xb5ca7170>, 0.0, 0.0, 0.0, 0.0]]

can you help me how to convert this "<gurux_dlms.GXDateTime.GXDateTime>" to date and time . i need to print this as particualr date&time.

And one more thing i need in python Gurux DLMS SDK how to enable keep alive for initial connection.

Please respond for above mentioned issues as soon as possible .

Hi Mikko,
Thank you for quick response. I got below output

07 E8 0B 0B 01 0B 2E 00 00 01 4A 00 | 1.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | /99 18:30:00:000000 | 0.0 | /99 18:30:00:000000 | 75 | 0.0 | 0.0

reading with Gurux Dlms director tool getting exact time but with SDK it's 07 E8 0B 0B 01 0B 2E 00 00 01 4A 00 not a correct time .

and Give me any idea for KEEP ALIVE for initial connection
