Question

STM32WB What are the asynchronous commands CPU2 sends to CPU1?

Looking for a list of all possible commands/scenarios where CPU2 sends commands to CPU1(APP).

I saw one specific case in AN5289 command during INIT, what are all the other cases?

Any examples/ Further documentation will be great.

What do you mean by asynchronous commands?

All communication exchanges in between the 2 cores are asynchronous.

At least during a scanning phase, CPU2 can return advertising report to CPU1.

You can also have a look at programming manual PM0271.
