Using RS232 I am looking to type a string into a terminal window and for the string to be echoed back to the terminal using micropython

Using RS232 I am looking to type a string into a terminal window and for the string to be echoed back to the terminal using micropython. However with the code shown below I get an error with the bytes being unable to convert to a string. Any help would be appreciated. Thanks

` from machine import UART, Pin, I2C
import utime

uart = UART(0, baudrate=9600, tx=Pin(0), rx=Pin(1))
uart.init(bits=8, parity=None, stop=2)
SDA = Pin(16)
SCL = Pin(17)

uart.write("Script Begin\n")

while True:
data = uart.read()

  if data is not None:
      # display input
      print('\nInput:')
      print(data)
      print(type(data))
       
      # converting
      output = data.decode('UTF-8')
       
      # display output
      print('\nOutput:')
      print(output)
      print(type(output))

  utime.sleep(3)`

And the error message you get is ... ?

The question around converting bytes/bytearray pops up every week or so, e.g. in #11588.
You might be able to find other solutions when searching for "decode" in discussions.

Traceback (most recent call last): File "<stdin>", line 42, in <module> UnicodeError:

Thats the error. I have given that solution a try but I still get the same error message

Your data is not valid UTF-8 (and you don't show us the problematic data).
You will need to use one of the workarounds mentioned in #11588.
