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 ...

We are developing a BLE device based on a STM32WB5MM. The device acts as a server and has configured the connection with bonding (and a passkey).We have a problem connecting to the device when several devices of the same type coexist in the same plac...

I have a STM32WB-based project (Stm32CubeIDE 1.15.0) using the STM32CubeWB 1.17.3 version and I'm not able to update the package version to the last one (nether 1.18 nor 1.19). There is not a prompt asking me to upgrade (the typical continue or migra...

I am using an STM32WB5MMG for a BLE application. The device acts as a server. I have configured a number of characteristics with indication permissions. How can I confirm the correct reception of the characteristics updates by the client? I mean, whe...

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...

I expect this:But I see that prebuild.bat edits se_keys.s(Using X-CUBE-SBSFU 2.6.2 and folder 2_Images from P-NUCLEO-WB55.Nucleo).

Just in case it happens to anyone else, the solution has been to indicate a different IRK and ERK for each device.I have questions about this at the production level that I will move in a separate post.
