I downloaded the source code for the DWM1001 module:
DWM1001, DW10001-DEV and MDEK1001 Documents, Source Code, Android Application & Firmware Image:
However, the file referred to in the DWM1001 Firmware API Guide: examples\ex1_TWR_2Hosts\tag\tag_cfg.c is missing, but there are two new examples. Is this done on purpose? If yes, maybe the firmware API guide should be updated accordingly?
