How to use X-NUCLEO-BNRG2A1 as standalone module (no host MCU) ?

Good morning everyone,

I purchased the X-NUCLEO-BNRG2A1 board, and I am interested in using it as a standalone device rather than as a BLE shield for an STM32 microcontroller.
According to the board specifications and pinout, this should be possible by directly programming the BLUENRG-M2SP module via the J12 connector and an ST-Link.

However, I am a little confused about how to start developing the firmware. If I understand correctly, the reference SDK should be STSW-BLUENRG1-DK, but it does not include any projects that can be directly imported into STM32 Cube IDE.

Could someone kindly provide me with some guidance on how to functionally integrate the SDK and the reference IDE, and suggest a practical starting point for developing a simple BLE server with a couple of characteristics?

Thank you for any suggestions,

Fabio Rossi
