Hi,
I am trying to read the energy meter em101+ from L&T using optical cable. I could see the connection getting established in the LCD screen as well as in dlms director gui.
But when I try to read further for serial number etc I get
"ServiceError Read exception. Service Unsupported" message. Wondering what could be the problem. Any suggestions ? screen shot attached
Do I required any authentication additionally ?
One more thing,
I have tried the same using the DLMS python package in ubuntu and I could get the serial number and few additional info (but no readings yet) sharing the trace log below,

gurux_net version: 1.0.17
