ISk5MT174 - TimeoutError: Read in SerialTransport timed out about iec62056-21

Hi

It seems your meter is using protocol mode A instead of C, that I have focused this library on so far.

In protocol mode A there is no baudrate switching so everything is still on 300 baud and the data is returned directly after the init request is send.

But you should be able to use the public functions of the client to read the data properly.

client.send_init_request() 
identification = client.read_identification() # Read the first line as the identification
data = client.read_response()  # Reads the data response

Thanks for your information, now it is working 👍

#!/usr/bin/python3

from iec62056_21.client import Iec6205621Client
import logging

# set up logging so you get a bit nicer printout of what is happening.
logging.basicConfig(
    level=logging.DEBUG,
    format="%(asctime)s,%(msecs)d %(levelname)s: %(message)s",
    datefmt="%H:%M:%S",
)

client = Iec6205621Client.with_serial_transport(port='/dev/ttyUSB0')
client.connect()

client.send_init_request()
identification = client.read_identification() # Read the first line as the identification
data = client.read_response()  # Reads the data response

Results:
same as response = ser.readline()...

great :)

Use the .data on the AnswerResponse to get a list of all DataSets.

So data.data in your code.
