Hi Krolken, I have a question, I am trying with my application and your library to read the value from an energy meter (Itron model SL7000). When trying to connect, a "Pipe Broken" error is generated. I don't understand where the problem is. I post the code. Thanks so much!

from iec62056_21.client import Iec6205621Client

client = Iec6205621Client.with_tcp_transport(address=('192.168.0.7', 4001),
                                                         device_address='17',
                                                         password='00000000')

client.connect()
client.standard_readout()
client.disconnect()

@arkjotgreen could you create an issue and also post the debug output from your program.

The compiler to stop over "client.standard_readout()", it's waiting for 20-30sec and generate this message.

Ok sorry i have testing this code with unittest, but without it, used a simple file with call function it's generate this output, always to this istruction client.standard_readout():

[Errno 32] Broken pipe
