Hi Marcos
First, I apologize for the delay in our response.
The platform Hexiwear can be supported by Kinetis Design Studio. Could you please help me check this guide Hexiwear writing first program by MIKROE.
Hexiwear is also supported by our MCUXpresso IDE and MCUXpresso SDK. If you have an interest, the links below will guide you to the downloads:
MCUXpresso SDK has basic demo source codes for Hexiwear, still, if you are looking for further support regarding the SDK and more topics, please reach out to the manufacturer of the device.
Hope this helps
