The reference OPEN UWB sniffer: firmware for a Qorvo DWM3000EVB driven by a host (a NUCLEO-F429ZI in the reference build; an nRF52840 with code changes) that captures IEEE 802.15.4z UWB frames and forwards them to Wireshark over a sensniff named pipe, with timestamps at the DW3000's 15.65 ps accuracy. Comes out of the SEEMOO/ETH Ghost Peak line of research. Honest limits: UWB has many PHY parameters (channel, preamble code, data rate, STS mode and length) that must be known IN ADVANCE to lock onto a link, and it forwards malformed frames too — so it is a research instrument, not a push-button capture. It does NOT break the STS or recover keys; it captures the over-the-air frames you can already decode.
