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?

Hello,

thank you for your interest in ST products. The SBSFU package is made for STM32 product lines and rely on certain mechanisms, eg. like RDP.

I will forward your question to our colleagues supporting BlueNRG products and ask them for qualified answer. OTA-wise there is AN4869

Best regards,

​Hello

As pointed out by Roman SBSFU is not addressing BlueNRG familiy.

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)
