Hi,

Your settings are different than the meter expects. Try with this:

python3 main.py -S /dev/ttymxc2:9600:8None1 -d India -t Verbose

Hi Srikanth,

Check your baud rate. The meter should reply if the baud rate is correct and your cable is connected correctly.

Hi Srikanth,

You are now using the Public Client and I believe that you need to change the client address and authentication level to see all profiles.

You can see the correct command line arguments when you select the meter in GXDLMSDirector.
