What is the CubeProgrammer button "Start wireless stack" actually doing and can it be automated?

[A.D.]

Could you shed some light on what the button "start wireless stack" actually does?

1) Is there some flag in flash that has to be set after flashing the wireless stack? Or is it just an option byte or something?

2) Why is this seperate button necessary? It would be easier and less likely to result in long debugging sessions if flashing the stack would automatically start it as well.

3) Can this process be automated via the CubeProgrammer to have a single to click to install and start wireless stack?

Hello @A.D. 

At the end of wireless stack installation, FUS is responsible of setting boot on wireless stack. So yes it shall start automatically.

Usually, the reason it may not start (from user perspective), is that some extra FUS_GETSTATE commands would have been sent after the end of the operation and while wireless stack already started. Which makes the wireless stack (at reception of 2 FUS_GETSTATE commands) go back to FUS. 

In this situation we will need to Start the Wireless stack manually using a separated button to go back to wireless stack.

That's why we need to have a separated button for this function.

Best Regards.
