Hi @Community member ,
You will find it under this path on the downloaded STM32CubeWB firmware package: STM32CubeWB/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/.
You can refer to the Release_Notes.html files for more details on how to use it.
I believe that the eLearning WB Bluetooth mesh - 4 STM32CubeWB Bluetooth LE Stack installation will be helpful for you.
A complete set of courses to start with your STM32WB based applications is available on this link.
