I just downloaded the BlueMicrosystem2_V2.2.0 and build with AC6 (System Workbench).
The project I trying is :
What I have noticed is following :
#endif /* STM32_NUCLEO */
My understanding in gcc, "#elif" would not be supported. Since the project is using the Defined Symbol options.
I have to change it to following in order to have the code build.
#elif defined STM32_SENSORTILE
