with a nearly 10 cm long breadboard cable,
and I checked it with an Ohm meter

and the patch wires ate fine?

I don't understand what you mean.

I tried it with the rshell, the same problem.

Type "help()" for more information.

No response at all.

You wrote in my summary of understanding by merging your 2 replies:

GPIO0 (Pin 1) to GPIO9 (Pin 12)
GPIO1 (Pin 2) to GPIO8 (PIN 12)

Is this a Typo too?

You wrote:
Works fine here, after connecting GPIO1 (Pin 1) to GPIO 8 (PIN 12).
GPIO0 (Pin 1) to GPIO9 (Pin 12) is required to communication the other way around.

My Question:

Why is GPIO1 AND GPIO0 assigned to PIN 1?

Hello, I'm an absolutely beginner in Micropython Programming. I don't know how I can ask for help. I have installed the latest firmware, by enabling UART support and I have taken the example from the Raspberry Pi Pico Python SDK. It doesn't work. After this I tried this code: from machine import UAR...
