Firmware C API UWB scanning

Hi everyone,
during testing with the DWM1001 modules a question of analyzing the connections between tags and anchors came up.
I know there is the “quality factor” available after positioning, but I would be interested in a per ranging metric. Something like RSSI, which does not seem to be supported in PANS or even DWM1000 from what I gathered in the forums up to now.
But in the “dwm.h” file there is a structure “dwm_uwb_scan_result_t” and I wanted to ask what the mode and rssi members contain exactly.
The documentation (API Guide) is not really descriptive regarding this struct and accompanying functions.

Best regards,
Thorsten Fuchs
