I'm using the SPBTLE-1S BlueNRG-1 module on a custom PCB with a STM32L4R9ZI MCU. The SPBTLE-1S module and the main MCU are connected trough SPI. The SPBTLE-1S module can be flashed with various firmwares provided by ST. Which one should i choose? I would like to have it compatible with the code generated by the X-CUBE-BLE1 pack on CubeMX.
