Does this require a specific micropython firmware version ? APPARENTLY NOT

[Philj6321]

Description

UPDATE - I've just tested it with firmware release v1.23 -0 and it works, at least the provided samples seem to.

I've tried for most of the day yesterday to get this to work with a Pico W - any examples I can find seem to use an earlier version of Micropython (Micropython v1.19.1-1008-gc046b23ea)

No matter what I do I always get this error returned. (See log output)

Reproduction steps

...

MicroPython version

v1.22.2

MicroPython board

Raspberry Pico

MicroPython Modbus version

2.3.7
