I have the following question: Is It possible to use SBSFU on BlueNRG-M2 module? Is There a X-CUBE-SBSFU package or similar to use with this module to implement firmware security update via OTA?

[DFior.1]

I followed the webinar "Discover our STM32 security ecosystem, from theory to practice online workshop".

I had to use the module BlueNRG-M2 , is there a package or other to implement firmware update security in this module?

Thank you

Hello,

just copying the answer provided in another post by Dominique

OTA-wise there is AN4869

THe BueNRG-2 is offering OTA , and basic flash read out protection.

The BlueNRG-LP (full 5.0) available at st.com is integrating secure boot and fw authentification mecanism (valid over OTA as well). I would recommand so if you are looking for low cost BlueNRG solution but with robust security to go to BlueNRG-LP , you will collect the needed information here.

THe BlueNRG-2 might fit but here only protection is flash read out

If concern is only OTA, in the AN pointed out by Roman description is done, associated code example is Service Manager and good to know on ghithub associated OTA source code example for IOS & Androind is available (ST BLE Sensor App)

Best regards
