User c code upload

How can I load the customization code I wrote for the DW1000 module without the PANS library and run both? When I upload the code I wrote, PANS is deleted. API Guide says user can write additional c code and use it in module. I have uploaded the user c code according to the document many times, but this time PANS does not work on the device.

Hi @ramazan
you are allowed to write a small user code on the top of the PANS library. You need to follow the DWM1001-Firmware-User-Guide.pdf and DWM1001-API-Guide.pdf + the code examples. YOU can find it here:
