Appendix H STM32WB Series specificities
H.1 Compilation process
A specific project (Loader) implementing the firmware download feature (over the Ymodem
protocol) is provided in order to make easier the integration of over-the-air download
capability (Bluetooth Low Energy protocol for STM32WB Series).
Figure 53 outlines the additional step 0 in order to compile then integrate the Loader into
SBSFU during the compilation process.

H.2 Key provisioning
Before the first execution of the SBSFU example, the symmetric key used for AES
cryptographic functions must be provisioned into the Cortex
