How to integrate BlueNRG-332 over SPI?

[Akash03]

I'm using the "STEVAL-IDB012V1" Development board with STSW-BNRGLP-DK Software.

I need to interface BlueNRG-332 with another microcontroller via SPI protocol, data flow will be:
MCU > (via SPI) > STEVAL-IDB012V1 > (via Bluetooth) > End user and vice versa.

Is there any supporting firmware in the SDK for this flow? Or should I code?

Thanks and Regards

Hello,

If your goal is to use BlueNRG-332 as network processor (meaning you flash BlueNRG with DTM SPI FW and your host micro is handling BLE application interfacing BlueNRG APIs through SPI) then you have documentation about this SPI network copressor possibility in SDK documentation.

Also few project examples based on that configuration (with STM32L4 as host) are included in SDK under BlueNRG-LP_LPS DK 1.4.0\Projects\External_Micro  .
