Hi Fabi G,
Do you mean the HEXIWEAR code download from this link?
GitHub - MikroElektronika/HEXIWEAR: HEXIWEAR firmware
The project on this package is using KDS IDE, not the MCUXpresso IDE, so if you use the MCUXpresso IDE, it will have problems.
Please refer to the HEXIWEAR - Getting started.pdf in folder : HEXIWEAR-master\HEXIWEAR-master\documentation
You will find the project is based on KDS.
Wish it helps you!
Have a great day,
Kerry
