It works perfectly!  Thank you very much!

Hi everybody!

I'm working with a RS232 bricklet, connected to a weighing machine. I have to send a code to connect (S02) and ask for a measure (MSV?) to this device, but i don't receive responde with the value of the weight.

    ipcon = IPConnection() # Create IP connection
    rs232 = BrickletRS232(UID, ipcon) # Create device object
    ipcon.connect(HOST, PORT) # Connect to brickd

    rs232.write(*string_to_char_list('S02'))

    rs232.write(*string_to_char_list('MSV?'))

    time.sleep(1)

    buffer=rs232.read()

The value of buffer is always the same and the length of the message is 0, so i understand is not a valid response. I have tried adding the characters \ r \ n to the end of the string and the result is the same.

However from Brickviewer if I enter both codes in the input field (first S02, Intro and then MSV? and Intro again) I get a valid response with the correct measure.

What could be the problem?

Thank you very much and excuse my english
