Basic steps to get OPENTHREAD up and running

Has anyone got a simple example of the steps needed to get THREAD working? I have followed the application notes and cant get things working :(

I have got the STM32WB55 nucleo board running with OpenThread FTD CLI example code nicely, but would like to make the same functionality without the examples.

From Stm32CubeIDE, I select New Project -> select the same chip that is on the nucleo board. I set SEM/IPCC/Clocks/OpenThread.

The first issue is errno is not defined and adding in the C files allows it to compile.

extern int errno

The code just hangs in the main loop.

One observation on the UARTS for OpenThread, even when you pick that you dont want a CLI, it still wants a UART to be set in the GUI.

Any help would be greatly appreciated
