I'm having issues with a project based on an STM32WB5MM where some devices fail to operate BLE (like advertising, for example). The project integrates SBSFU and BLE_ota. I'm reviewing the linker files and I see differences in the management of the BL...

Currently, the STM32CubeProgrammer CLI allows loading keys into the second CPU of an STM32WB using the wusrkey command. For example, we use it in combination with SBSFU. This command currently requires a path to a file containing the binary key.My re...

We have an application running on an STM32WB55M. This user application makes use of standby mode, and the device is able to exit it when the configured pin changes state.However, once the SBSFU is integrated with the BLE_ota application, the user app...

Hello,We are developing a product based on a STM32WB5MMG. We have configured the SBSFU with OTA (Asymmetric with AES encryption scheme). Everything is working great and I have only one question that came to my mind during the last commit...The CBC ke...

Hello,We are working on a device based on a STM32WB5MM. The module has configured the SBSFU, the BLE OTA and the user application.We have defined some sections in the flash memory to store device data, like the serial number or the pin code used for ...

Solved.

More info. The system wakes ups and counter program goes to the Ble_ota app region. I've reattached (debugged) the BLE_ota application on the fly and see that it is executing the run function of the sequencer, but without any Bluetooth activity. I un...

When the debugger is enabled, everything works correctly, but if I disable the debugger, the device doesn't wake up. I understand that having the debugger enabled keeps the system clock active, which is why the wakeup works. But if I want to disable ...

I see that SE_CRYPTO_AES_ReadKey uses SHCI_C2_FUS_LoadUsrKey in P-NUCLEO-WB55.Nucleo/Applications/2_Images/2_Images_SECoreBin/Src/se_crypto_bootloader.c. So, why is se_key.s edited and needed??I have checked that is needed to access the public key of...
