Hello ST Community,
I’m currently working on a project where I’m using the STM32L475RGT6 MCU to interface with the BlueNRG-M2SA Bluetooth module via SPI. The goal is to establish BLE communication between the MCU and a mobile device. However, I’ve encountered a few challenges and would appreciate guidance or reference material.
If anyone has:
- A working DTM firmware or BLE SPI reference for STM32L4 + BlueNRG-M2SA
- A minimal working .ioc + main.c + app_bluenrg_2.c
- Any tips on pin configuration, middleware integration, or BLE stack setup
