I am working with the stm32wb55 mcu. How can I determine programmatically from CPU1 if the correct FUS and BLE stack are programmed in flash?

Hi,

you can read stack version by :

WirelessFwInfo_t pWirelessInfo;

if(SHCI_GetWirelessFwInfo(&pWirelessInfo) == SHCI_Success){}

I think there is something for reading FUS version. If you enable CPU2 without correct stack, I think you have infinite waiting in the sequencer or error interrupt.
